The
2009 Pacific typhoon season has no official
bounds; it runs year-round in 2009, but most tropical cyclones tend to form in the
northwestern Pacific
Ocean
between May and November. These dates
conventionally delimit the period of each year when most tropical
cyclones form in the northwestern Pacific Ocean.
The scope
of this article is limited to the Pacific Ocean, north of the
equator and west of the International Date Line
. Storms that form east of the date line and
north of the equator are called hurricanes; see
2009 Pacific hurricane season.
Tropical storms formed in the entire Western North Pacific basin
are assigned a name by the
Japan Meteorological Agency.
Tropical depressions formed in this basin are given a number with a
"W" suffix by the United States'
Joint Typhoon Warning Center.
In addition, the
Philippine Atmospheric, Geophysical and Astronomical Services
Administration (PAGASA) assigns names to tropical cyclones
(including tropical depressions) that enter or form in the
Philippine area of responsibility. These names, however, are not in
common use outside of the Philippines.

The
Philippine Atmospheric, Geophysical and Astronomical Services
Administration (PAGASA,) reported on January 4, that they were
expecting a total of 19
tropical
cyclones or less during the upcoming typhoon season. They then
reported on June 15 that seven to ten tropical cyclones were
predicted to move through their area of responsibility within the
next 3 months. After their January prediction of 19 cyclones was
surpassed by Tropical Depression Tino forming it was announced that
they were now expecting one or two more cyclones in their area of
responsibility, before the end of the year. In May 2009 the
Vietnamise National Centre for Hydro Meteorological forecasts
predicted that the number of tropical cyclones causing damage to
Vietnam during the season would be more than the average of six
cyclones.
On June 30, the Central Weather
Bureau of Taiwan
predicted
that 24 to 27 tropical storms would form over the Western Pacific,
with 3 or 5 tropical storms affecting Taiwan.
Since the
2000 season, the
Laboratory for Atmospheric Research at the City University
of Hong Kong has forecast the expected number of tropical
cyclones, named storms, and typhoons in a
season with forecasts released in April and June. This
season, the CityUHK is predicting an about average season. An
average season, according to the CityUHK, has 31 tropical cyclones,
27 named storms, and 17 typhoons. In its April forecast, the
CityUHK predicted 31 total tropical cyclones, 27 named storms, and
18 typhoons. It also forecast that 4 tropical cyclones would make
landfall in
Southern China, all of
which are expected to be in the early season (between May and
August). A normal season sees 5 such landfalls, of which 3 are
early and two are late (September to December). In its June
forecast, the CityUHK lowered its prediction of how many tropical
depressions would form this season to 30 whilst leaving their
predictions of how many tropical depressions would intensify
further the same as their April forecast. They also reported that
due to a developing
El Niño event that
only three systems were expected to make landfall on China between
July and December.

So far in 2009, a total of 39 tropical depressions have formed and
been monitored by any of the
National Meteorological and
Hydrological Services in the Western Pacific, which is defined
as being between 180° and 100°E. The first tropical depression of
the season formed on January 3, 2009 and was subsequently named as
Auring by PAGASA. The final warnings on Auring were issued on
January 6, as the depression dissipated after causing about $500000
(2009 USD) in damage and killing two people.
There were no systems
monitored by any of the warning agencies until early on February
12, when PAGASA reported that Tropical Depression Bising had formed
about 140 km (85 mi) to the east of Surigao City
on Mindanao
Island. Bising remained weak and was downgraded to an area
of low pressure the next day after causing minor effects on the
Phillipines. The next tropical depression of the season did not
form until early on April 30, when PAGASA reported that Tropical
Depression Crising had formed southeast of Luzon.
Storms
Tropical Depression Auring
Tropical
Depression Auring formed as a tropical disturbance late on December
30, 2008, to the southeast of Manila
in the
Philippines
. Over the next few days the disturbance
gradually developed before early on January 3, the
Philippine Atmospheric, Geophysical and Astronomical Services
Administration (PAGASA) and the
Japan Meteorological Agency
(JMA), reported that the disturbance had intensifed into the first
tropical depression of the season with PAGASA assigning the name
Auring to the depression. As the Depression was moving into a high
level of vertical
wind shear, it did not
develop any further and late on January 5 as the
baroclinic zone approached Auring, it was
downgraded to a
low pressure area
by PAGASA before the JMA followed suit the next day as it was
declared as dissipated by the JTWC.
Heavy
rain from Auring produced severe flooding in the eastern Philippines. Two people were killed and nine others were
left missing. A total of 305 homes were destroyed and another 610
were damaged. In addition, an estimated 53 hectares
(130.9 acres) of rice and 3.5 hectares (8.6 acres)
of corn were damaged. About 43,851 people were affected by the
depression and damages were estimated at
PHP 23 million
($498,318
USD).
PAGASA Tropical Depression Bising
Early on February 12, PAGASA reported that an low pressure area
located about 140 km (85 mi) to the east of Surigao City
had intensifed into a tropical depression. During that day the
depression gradually moved towards the west with its peak
windspeeds estimated at 45 km/h (30 mph) and its peak
pressure estimated at 1000 hPa (mbar). Early the next morning
after the depression had made landfall on Dinagat Island, PAGASA
released its final advisory as the depression had weakened into an
area of low pressure.
An estimated 473 passengers and several vehicles were stranded in
Liloan and Ormoc due to ferry cancellations. In Cebu, an estimated
1,600 passengers were also stranded due to the depression. Late on
February 13, the remnants of Bising brought scattered rainshowers
across Southern Luzon, Bicol Region, and Visayas, then dissipated.
The
rainfall led to mudslides on Cebu Island
which blocked the Cebu Transcentral
Highway.
PAGASA Tropical Depression Crising
Early on April 29, the JTWC reported that an area of disturbed
weather had formed about 430 km to the southwest of Manila in
the Philippines. Satellite imagery showed an elongated low level
circulation center with broken convective banding wrapping the
southern edge of the disturbance, located within an area of low
vertical wind shear. During the day the disturbance gradually
consolidated and started to intensify under the influence of an
anticyclone. As a result of this, a Tropical Cyclone Formation
Alert (TCFA) was released by the JTWC later that day. Early the
next morning PAGASA designated the disturbance as Tropical
Depression Crising, and reported that Crising had peak windspeeds
of 55 km/h (35 mph). Later that morning PAGASA put parts
of Western Luzon under public storm warning signal number one
whilst the depression was moving slowly towards the west within the
South China Sea. Later that day the JTWC cancelled the TCFA on
Crising as the low level circulation center was now poorly defined
after it had interacted with another tropical disturbance that
later became Tropical Storm 01W. However PAGASA kept issuing
advisories on Crising and then early on May 1 PAGASA cancelled all
the Public warning signals which were in place for western parts of
Luzon. Early the next day, PAGASA reported that the tropical
depression had weakened into a low pressure area and the final
advisory was issued.
Heavy rains produced by the
outer bands of
Crising caused flooding in western areas of the Philippines,
affecting an estimated 2,500 people.
The worst flooding
occurred in Lucena
City
where ten villages were isolated. Areas
along the
Bucon and
Inalmasinan Rivers were inundated and
sustained significant crop losses. Several animals reportedly
drowned in the region. Several roads were impassable due to
landslides or were washed out by floodwaters. One bridge was
destroyed in the town of Mercedes.
Typhoon Kujira (Dante)
Early on
April 26, an area of disturbed weather formed near the coastline of
Baler
, capital of
the Philippine's Aurora
province. It was formerly a tail end of cold front
that passed by Northern Luzon
.
JTWC assesed that the
area of a disturbed weather potential of becoming developing into a
significant Tropical Cyclone within 24 hours as "fair". However, on
April 28, JTWC downgraded the disturbance as dissipating because of
interaction with nearby middle Tropical Depression Crising and JMA
Tropical Depression 03.
A few days later, the disturbance moved
south-westward, and late on April 30, the disturbance made landfall
at Albay
. On
May 1, JTWC again upgraded the disturbance into having a potential
to form into a significant Tropical Cyclone within 24 hours to
"fair".
And later that day,
PAGASA classified the disturbance as a tropical depression,
naming it "Dante" and issued public storm warning signal number
one in the provinces of Camarines Norte
, Camarines
Sur
, Albay, Sorsogon
, Catanduanes
, Masbate, Burias Island
, and Southern Quezon. PAGASA also reported
that Dante made landfall in the vicinity of Sorsogon within the Bicol region of the Philippines.
Early on May 2, JTWC issued a
TCFA as the depression was
in an almost stationary position. Later that day, JMA classified
Dante as a full depression. Early the next morning it became a
tropical storm and was named Kujira. Kujira continued to strengthen
and was upgraded to a severe tropical storm that afternoon.When it
was over the Philippines it killed 27 people while 9 others are
missing. The JMA upgraded the system to a typhoon early on May 4.
Kujira intensified quickly, doubling in strength from a Category 2
typhoon to a Category 4-equivalent typhoon within 24 hours. On May
6, The JTWC reported that Kujira was in its beginning stages of
becoming extratropical, with the low level circulation center
almost fully exposed in association with increasing vertical wind
shear and lower sea surface temperatures in the region. Late that,
JMA downgraded Kujira to a Severe Tropical Storm as strong wind
shear weakens the system. Then early on May 7, JTWC issued its last
advisory on Kujira, already reporting it as an extratropical
system. JMA continued to issue warnings on the system while at the
same time it was downgraded to a tropical storm. Later on May 7,
Kujira weakened further, becoming a fully extratropical
cyclone.
While in the Philippine area of responsibility, Kujira caused some
625,709,464 worth of damage to crops and livestock in Albay,
Camarines Norte, Masbate and Sorsogon. It also caused some 102
million pesos worth of damage to communal irrigation systems in the
region. The NDCC update as of 6AM PST May 12 declared 28 dead, one
missing and 5 injured. Further, 383,457 persons in 609 barangays of
60 municipalities and 4 cities in 5 provinces of Region V were
affected by the storm. Damages are worth PhP 1,228,422,344 million
or PhP1.228 billion of which PhP 625,709,464 are agricultural
losses and PhP 529.525 million in infrastructural. Houses destroyed
were at 2387, of which 138 were total and 2249 partial.
Tropical Depression
Late on April 28, the JTWC reported that an area of disturbed
weather had persisted in an area of low vertical windshear to the
southeast of Yap. Deep convection was wrapping into a poorly
orgainzed but consolidating low level circulation center. However
over the next few days its low level circulation center weakened
with convection becoming very shallow and disorganised before it
was declared as a Tropical depression on May 1 by the JMA. The JTWC
then released a Tropical Cyclone Formation Alert early the next day
as the low level circulation center had become well defined and
convection increased with sea surface temperatures also becoming
favourable for development. However the alert was cancelled later
that day after the depression had peaked at 55 km/h
(35 mph), as the low level circulation center had started to
move under the upper level jet located to the north of the
depression which had caused the vertical windshear over the system
to increase. As a result of this the low level circualtion center
began to detach from the convection and was loosing its tropical
characteristics and was predicted to become a very strong
extratropical low. However the JMA continued to issue advisories on
the depression until early on May 4, when they downgraded it to an
extratropical low.
Typhoon Chan-hom (Emong)
On May 1, an area of convectional cloudiness associated with an
area of disturbed weather formed southeast of Nha Trang, Vietnam
and associated with a remnant of Tropical depression Crising to
form a new stronger area of disturbed weather system. JTWC
monitored the disturbance as "Fair" for developing due to low
vertical wind shear and an upper level anticyclone to the east of
the system. Later on the JMA designated the low pressure as a minor
tropical depression reporting the outlook track as southwestward.
The JTWC issued a
TCFA on the system once the
convection increased and became better organized although with an
exposed LLC east of its convection. Early morning of May 3, the JMA
begun issuing tropical cyclone advisories on the system forecasting
it to become a tropical storm later in the afternoon as it tracked
eastwards. On May 3, the JTWC designated the disturbance as
Tropical Depression 02W, and the JMA named the storm Chan-hom.
Later on May 4, Chan-hom strengthened into a severe tropical storm.
On May 6, the system moved into the Philippine Area of
Responsibility from the west and was named as Emong. Later that day
the JMA upgraded the severe tropical storm to a typhoon.
On May 7,
PAGASA reported that Chan-hom had made landfall at the northern tip
of Bolinao,
Pangasinan
. After traversing Pangasinan it lashed
La
Union
, Ilocos
Sur
, Benguet
, Nueva Vizcaya,
Ifugao
, Mt.
Province, Kalinga
and Isabela
. Pangasinan (which recorded 150mm of rain
from Emong) and La Union were the worst hit.
The provinces in
Central Luzon, Ilocos, Cordillera Administrative
Region and Cagayan Valley,
together with Metro
Manila
and parts of Southern Luzon, generally experienced
more than 100 mm in the 24 hour period on May 7. Rains,
however, lasted from May 6–8. NDCC updates on 6:00AM on May 13 put
dead at 50, injured at 47 and missing at 13 and damage worth 690
million pesos in agriculture, infrastructure and private property.
It further left 204,000 persons affected, damaged 23280 houses of
which 6080 are totally damaged and 17200 partially damaged in
Pangasinan and induced 11 landslide occurrences in Zambales and
Cagayan PAGASA expected the typhoon to weaken quickly, which it
did. On May 8, Chan-hom was downgraded to a Tropical Storm and
later, to a Tropical Depression. JMA issued its last warning early
on May 9, followed by the JTWC. PAGASA held on to Emong (Chan-hom)
until much later that day, when it was declared an area of low
pressure. JTWC then re-issued advisories on the restrengthening
depression on May 10. Later on May 11, Chan-hom became a
subtropical depression , therefore, JMA and PAGASA designated it a
tropical depression while JTWC declared it dissipated , PAGASA
reported Tropical Depression Chan-hom degenerated into Subtropical
Disturbance ex-Chan-hom and issued the final advisory for the
system because it had almost completely dissipated. However, JMA
did not issue the final advisory for the tropical depression until
early on May 13, when then circulation dissipated and it began
accelerate northeastward in association of the jet stream and it
was forecast to become extratropical or be absorbed by a cold
front.
Severe Tropical Storm Linfa
On
June 10, the JTWC began monitoring an area of disturbed
weather that was situated about 140 kilometres (85 mi)
southeast of Palau
.
Satellite imagery depicted an elongated low-level circulation, with
deep convection centered along the southwestern portion of the
system. Over the next couple of days, the disturbance gradually
developed with the JMA declaring the system as a tropical
depression early on June 14 whilst the JTWC issued a TCFA.
However the TCFA was later cancelled due to the convection
dissipating, whilst the JMA downgraded the depression to an area of
low pressure. Over the next two days, the system moved across Luzon
and began to regenerate. Early on June 17, a second TCFA was
released by the JTWC whilst the JMA reported that the system had
reintensifed into a tropical depression.
Later that day, the
JTWC designated the system as Tropical Depression 03W whilst the
storm was situated about 705 km (440 mi) south-southwest
of Kaohsiung,
Taiwan
.
Following further development of the depression, the JTWC upgraded
it to a tropical storm late on June 17. The JMA then followed
suit early the next morning assigning the name
Linfa to
the storm. Throughout the rest of the day limited poleward outflow
prevented linfa from intensifying. During June 19, Linfa
intensified further and became a severe tropical storm with an eye
feature starting to appear on microwave imagery. After interacting
with a nearby upper-level low, outflow significantly improved later
that day, fueling further strengthening, before the next day the
JTWC upgraded Linfa to a
typhoon as it
reached its peak windspeeds of 140 km/h (85 mph)
110 km/h (70 mph
10-minute winds). Later
that day convection near the center of the circulation to decrease
with the eye no longer visible. Upper-level wind shear rapidly
increased, preventing re-intensification of the cyclone. Linfa then
began to interact with land and was downgraded to a tropical storm
by the JTWC on June 21 and then during that afternoon the
storm made landfall on the southern Chinese provence of Fujian.
Deep convection then rapidly dissipated with both the JMA and the
JTWC downgrading Linfa to a Tropical depression by early on July
22, as the storm moved away from the Chinese coastline. The system
later dissipated just offshore with a circulation was no longer
evident on satellite imagery.
A total of seven people were killed by Linfa, whilst (2009 US)$110
million worth of damage was done by Linfa, as it affected China,
Taiwan, Hong Kong and the Philippines. A 498-tonne oil tanker was
run aground in southern Taiwan by large swells of up to 5.6 m
(18 ft). In Taiwan two people were hit by fallen trees, whilst
power cuts were reported in
Chiangchun as
well as other parts of China and Taiwan. A total loss of
NT$400 million (US$12.1 million) was
suffered by the agricultural sector in Taiwan whilst in mainland
China, Linfa produced torrential rainfall which led to severe
flooding. Following a landslide, one person was killed. Flood
waters destroyed 100 homes and inundated 10,000 others as well as
an estimated 32,000 hectares of farmland in Fujian Province.
In
Meizhou
, Guongdong Province, flash flooding resulted in
five additional fatalities after 413.7 mm 19.22 in of
rain fell within a nine-hour span. A total of 362 homes were
destroyed in the town and infrastructure was severely damaged.
Additionally, an estimated 20 million people were affected by
the storm.
Tropical Storm Nangka (Feria)
On June
16, an area of disturbed weather formed about 170 km
(120 miles) to the northeast of Palau Island
. In the next few days, the disturbance
showed improvement but, its LLCC was undefined. Early on June 20,
the disturbance suddenly strengthened and its LLCC began to
consolidate as well as significant banding all over the system. The
disturbance was also located under low vertical wind shear. Early
on June 22,
JTWC issued
an advisory that the potential of the formation of a significant
tropical cyclone within 24 hours was upgraded to "Fair" because of
its well-defined LLCC and was located in a favorable area. Around
0600 UTC that same day, the
JMA classified the disturbance
as a minor Tropical Depression, while the JTWC released a
TCFA on the disturbance.
This was
because convection had begun to organize and upper-level analysis
showed a cyclonic center on the east, just west of Guam
and a
cyclonic flow around its consolidating low level circulation
Centre. After 4 hours, JTWC issued its first warning and
named it as Tropical Depression 04W. Early on June 23,
PAGASA issued its first warning on the Tropical Depression and
assigned its local named "Feria".
In the afternoon, Nangka made its first
landfall over Hernani, Eastern Samar
at 5:00 pm PST (0900 UTC). and made its second
landfall in Masbate around 10:00PM PST ( 1400 UTC). On June
24, Nangka rapidly slowed down while moving over Mindoro. The storm
then made its third landfall at Calapan City, Mindoro at 12 am PST/
0430 UTC. After crossing Mindoro for 8 hours, PAGASA downgraded
Nangka into a Tropical Depression, while both the JMA and JTWC
still classified Nangka as a tropical storm on that day. Early on
June 25, Nangka move into the South China Sea, with PAGASA issuing
their final warning. In the evening of that same day, both JMA and
JTWC downgraded Nangka into a tropical depression due to its low
level circulation center is started to deteriorate.
By midday of June 26,
it made its forth landfall in the Guangzhou
province in China, passing through the northern
part of Hong
Kong
. In the afternoon of that day, both JMA and
JTWC issued their final warning on Nangka. Its remnants completely
dissipated by June 27.
In Eastern Samar, more than 800 people were stranded after ferry
service was canceled. High winds downed a large tree, destroying
the roof of one home and damaging three cars. Unusually strong
severe thunderstorms developed over parts of the Philippines along
the
outer bands of Nangka. In San Pascual,
Bauan and Batangas City, large hail fell during a strong storm.
Residents reported that they have never seen hail before. In
Barangay, 4 in Bauan town, a rare tornado struck, downing several
trees, damaging homes and signs. Heavy rains produced by the storm
also flooded numerous regions, some reporting waist-deep water.
Later reports confirmed the tornado destroyed 23 homes. In Cebu,
one person was killed and seven were left missing. At least 500
people were also left homeless due to the storm. In Cavite,7000 was
stranded on the port due to Nangka's winds and heavy rains. about 4
feet is the water wave in Cavite.
In Albay, more than
300 ship passengers were also stranded at the Albay port, Tabaco,
Albay. In Navotas
and Malabon
, the Navotas — Malabon river produced a 3 foot
high tide in the area.
As of 24 June, Nangka (Feria) has caused 6 deaths and left 11
people missing. Property damage from the storm is estimated at PHP
2.8 million (US$54,000).
Tropical Storm Soudelor (Gorio)
Late on
July 7, the JTWC reported that an area of disturbed weather had
formed about 900 km (560 mi) to the northwest of Yap
.
Deep convection was embedded in a broad, weak, poorly defined
circulation that was starting to be enhanced by a
Tropical Upper Tropospheric
Trough (TUTT) cell to the east of the system. Over the next
couple of days, gradual development took place before a TCFA was
released by the JTWC early on July 9 as PAGASA designated the
system as Tropical Depression Gorio. Later that day both the JMA
and the JTWC reported that the depression had formed and started to
issue warnings on the depression, with the JTWC designating it as
05W. On July 10, PAGASA issued their final advisory on
Tropical Depression Gorio as it moved out of their area of
responsibility. Hampered by an unfavorable upper-level environment,
the depression barely intensified into a tropical storm early on
July 11. Upon becoming a tropical storm, the JMA named the
system
Soudelor reporting peak winds of 65 km/h,
(40 mph).
Later that day the JTWC reported that
Soudelor had weakened into a depression; however they re-upgraded
it to a tropical storm as it moved closer to Hainan
Province
.
Shortly
before landfall in Leizhou Peninsula
, China, the JTWC downgraded the storm to a tropical
depression, then as Soudelor moved back over water and into the
Gulf of
Tonkin
, the JTWC issued their final advisory on the
depression, however the JMA continued to monitor the storm until it
had made landfall near Fangchenggang
, China several hours later.
As a tropical depression, Soudelor brushed northern Luzon in the
Philippines, producing upwards of 330 mm (13 in) of
rainfall which resulted in flash flooding and landslides in at
least ten villages.
In China torrential rains in Hainan
caused
significant flooding that killed 15 hikers and left several others
missing. Numerous roads were also cut off or destroyed by
landslides and 30 villages were inundated with flood waters. The
remnants of Soudelor produced widespread torrential rains in
Northern Vietnam on July 13. Rainfall totals peaked at in the
region.
Heavy rainfall, amounting to , was also
recorded in Hanoi
. The
capital city experienced flash flooding, inundating numerous
streets and buildings. Two men were killed by lightning strikes
associated with the storm. Officials reported that at least 13
large trees had been downed by high winds. Flood waters in the
hardest-hit areas reached a depth of . One person was killed after
being swept away. A
tornado also touched
down during the storm, destroying the roofs of three homes.
Thousands of hectares of croplands were inundated by flood waters.
Following the storm, 1,000 tonnes of rice was allocated for victims
of the floods.
Tropical Depression Huaning
On July 10, the JTWC reported that an area of disturbed weather had
persisted about 1065 km (660 mi) to the east of Manila.
The convection was consolidating with a good mid level circulation
and was located under a anticyclone and had started to show some
outflow into a trough to the northeast of the system. Early the
next day the JMA reported that the disturbance had become a minor
tropical depression. The depression then gradually developed during
the rest of July 11, with PAGASA naming the depression as Huaning
early on July 12 whilst the JTWC issued a Tropical Cyclone
Formation Alert on the depression. Early the next day PAGASA
upgraded Huaning into tropical storm whilst the JTWC designated the
depression as Tropical Depression 06W.
Later that morning
Huaning made its first landfall over Chungyang, Taiwan. On
the next day, both JMA and JTWC issued their final warning on
Huaning.
Typhoon Molave (Isang)
Late on
July 10, an area of disturbed weather persisted about 280 km
(175 miles), to the southeast of Yap.
Convection was wrapping into a poorly organized and drawn out low
level circulation center and was under minimal wind shear. It
gradually developed further throughout the next day with convection
continuing to consolidate over a low level circulation center.
However early on July 12, the JTWC reported that the disturbance
had dissipated, as outflow was being hampered by the outflow of
Huaning. However late on July 13, the JTWC reported that the
disturbance had rapidly redeveloped and released a TCFA on the
disturbance. Early the next day both PAGASA and the JMA designated
the disturbance as a Tropical Depression with PAGASA assigning the
local name of Isang to the depression. The Depression continued to
develop and was designated as Tropical Depression 07W by the JTWC
early on July 15, whilst PAGASA upgraded Isang to a Tropical storm
later that day. On July 17, JMA upgraded Molave as a Severe
Tropical Storm and Typhoon by PAGASA.
On morning of July
18, HKO
upgraded Molave as a Typhoon. Later that day,
Molave quickly moved into the South China Sea
. On July 19, at 1700 UTC or 1am HKT, Molave
made its first landfall. On the afternoon, as Molave move through
China, both JMA and JTWC issued their final warning as Molave
weakened into a Tropical depression. Molave killed at least four
people.
Tropical Storm Goni (Jolina)
Late on
July 25, the JTWC reported that an area of convection had formed in
a monsoon trough about 815 km (515 mi) to the northeast
of Guam. Deep
convection was flaring around the low level circulation center. An
upper level anticyclone and a tropical upper tropospheric trough
was providing outflow. Over the next few days the disturbance
gradually developed before the disturbance was declared as
dissipated early on July 28 as the low level circulation center was
not well defined and higher vertical wind shear affecting the
system. However the disturbance regenerated early on July 30 whilst
located about 630 km (390 mi), the disturbance's low
level circualtion center was elongated with indications of multiple
circulation centers. Later that day PAGASA reported that the
disturbance had developed into a tropical depression and assigned
its local name of Jolina. Jolina then intensifed further early the
next day and was reported to have become a tropical storm by
PAGASA, with the JMA designating it as a depression later that day.
Early on August 1 the JTWC issued a Tropical Cyclone Formation
Alert as deep convection had increased and was starting to
consolidate around a circulation center. However later that morning
Jolina made a landfall near to Casiguran, in the Philippine
province of Aurora before emerging out in to the South China sea
later that day. Early the next day the JTWC reissued their TCFA
whilst PAGASA issued their final warning on Jolina as it moved out
of their area of responsibility heading towards a landfall on
China. The JTWC then designated the depression as 08W later that
day as infrared imagery had shown deep convection was wrapping into
the low level circulation center. During August 3, the JMA reported
that the tropical depression had intensified into a tropical storm
and assigned the Goni to the cyclone. At 1700 UTC of August 4, Goni
made its second landfall over Macau. Early on the next day, JTWC
issued their final warning on Goni. On August 7, The Joint Typhoon
Warning noted that remnant of Goni re-entered into the Gulf of
Tonkin and had a poor chance of regenerating. Later in the day,
Joint Typhoon Warning Center reissued advisories on the system
upgrading it to a tropical storm near Hainan Island.
In the Philippines Goni (Jolina) death toll is 8 with 5 more
missing.
Goni (Jolina) affected 38,589 families or
160,038 people in 119 villages in 25 towns and five cities in
Ilocos
Sur, Batangas
, Cagayan
, Nueva
Ecija
, Rizal
, Mindoro
Occidental
, Palawan
, Iloilo
, Negros
Occidental
, Lanao del
Sur
, and Sultan Kudarat
town in Maguindanao
.Five people died in China when Goni passed
through. In Hainan province about 92,000 people had been evacuated
by the authories. 575 houses got destroyed and 2,311 damaged. The
storm also inundated than 68,000 hectars cropland.
Typhoon Morakot (Kiko)
Early on August 2, the JMA reported that the season's eleventh
tropical depression had formed within a monsoon trough about
1000 km (620 miles) east of the Philippines. The
depression remained weak, however, and later that day the JMA
downgraded it to an area of convection. Still later that day, the
JMA reported that the tropical depression had regenerated and that
deep convection was flaring on the western side of a partially
exposed low level circulation center. On August 3, PAGASA named the
depression Kiko as it moved through their area of responsibility,
after which (the same day) the JMA named the storm Morakot,
upgrading it to a Tropical Storm. The JTWC followed suit,
designating Morakot as 09W. The next day Morakot recurved,
reentering PAGASA's area of responsibility.
In the
Philippines, ten villages (Paudpod, San Juan, Batonloc, Carael,
Tampo, Paco, San Miguel, Bining, Bangan, and Capayawan) have been
submerged in 4-foot to 5-foot deep floods after the Pinatubo Dike
overflowed. Joint military and police rescue teams rescued 3
Koreans and 9 Canadian nationals. About 30,000 families were
affected by Morakot; eleven people are confirmed dead.
Three French
tourists
and two Filipino guides were killed in a flashflood caused by a
landslide. Thousands are trapped on rooftops or in trees
awaiting helicopter rescue attempts and thousands have lost their
homes. At least two have died from flooding. Landslides have
claimed the lives of two children and five miners are still missing
after a landslide destroyed their huts. Schools have suspended
their classes in the hardest hit area, and highways have been
closed due to landslides.
In Taiwan, where schools were closed ahead of the typhoon, Morakot
caused landslides, severe floods, blew down trees and billboards,
and stripped roofs from buildings. In a positive impact, Morakot
brought much-needed rain to Taiwan, ending a months-long drought,
and replenished reservoirs enough to warrant an end to water
rationing. On that island, two people were killed with four
missing. Almost the entire southern Taiwan (Chiayi, Tainan,
Kaohsuing, and Pingtung) are flooded by record-breaking heavy rain.
It is estimated that rainfall in Pingtung county may reach as much
as 2,500 millimeters, breaking all rainfall records of any single
place in Taiwan induced by a single typhoon.
South east China has evacuated 20,000 residents. A fishing boat has
capsized and search and rescue efforts have begun for nine missing
fishermen. A total of 34000 watercraft sought refuge ahead of the
storm.
Tropical Storm Etau
On August
6, an area of convectional cloudiness associated with monsoon
through was located about (620 miles) 1000 km southwest
of Iwo
To
, Japan. Satellite imagery shows an TUTT was
located to the northeast of the system. and the system is also
located under high vertical wind shear and favorable environment.
Late of August 7, JTWC upgraded the system and issued a TCFA
because of LLCC is partially exposed. while JMA also upgraded the
system as a minor tropical depression. On the next day, both JMA
and JTWC classifies the minor tropical depression as a full
depression. On August 8, JMA upgraded the system as a tropical
storm and assigned the name Etau.
In post-storm analysis, the JMA downgraded Etau to a tropical
storm, with peak winds of 75 km/h (45 mph).
Tropical Depression Maka
On August 13, the remnants of
Tropical Storm
Maka crossed the international dateline and moved into the
Western Pacific; where it was immediately designated as a tropical
depression by the JMA. Later that day the JTWC reported that the
depression was located about 1425 km (885 miles) to the
southeast of Wake Island, with deep convection developing over the
northern quadrant of a stretched out, low level circulation center
which was in an area of low to moderate vertical wind shear and had
a good outflow into an upper level trough. During the next day, the
JTWC issued a Tropical Cyclone Formation Alert on the depression as
the low level circulation center had developed further. Later that
day, the JTWC re-upgraded the disturbance to Tropical Depression
01C (Maka). Late the next day the JTWC upgraded the depression to a
tropical storm however, the JMA still classified the storm as a
depression.
Typhoon Vamco
On August 13, the JTWC reported that an area of deep convection had
persisted in an area of low vertical wind shear about 415 km
(260 mi), to the north of Kwajalein Atoll. A low level
circulation center was developing with the deep convection starting
to wrap into it whilst a tropical upper tropspheric trough was
providing a good outflow for the center. Over the next couple of
days the convection started to consolidate before early on August
16 a TCFA was issued by the JTWC as convective bands had started to
wrap into the low level circulation center. It was then declared as
a Tropical depression later that day by the JMA however the JTWC
did not follow suit until early the next day when they designated
the depression as 11W with convective bands wrapping into a well
defined low level circulation center. Both the JTWC and the JMA
upgraded it to a tropical storm later that day, with the JMA
assigning the name Vamco to the storm.
During August 18, the JMA reported that Vamco had intensified into
a severe tropical storm and was moving towards the northwest slowly
before early the next day along with the JTWC reporting that it had
intensifed into a weak typhoon. During that day Vamco kept
intensifying due to being in favorable conditions with the JMA
reporting that the typhoon had reached its peak wind speeds early
on August 20 of 165 km/h, (105 mph)
10-min
Sustained, however the JTWC reported that it had continued
to intensify during August 20, and reached its 1 minute peak wind
speeds of 215 km/h, (130 mph) early on August 21 which
made it a category four typhoon on the Saffir–Simpson Hurricane
Scale. Vamco stayed at its peak wind speeds until early on August
22 when both the JMA and the JTWC reported that it had started to
weaken, however due to the typhoon being in favorable conditions,
Vamco was able to maintain its typhoon status until early on August
25, when the JTWC downgraded Vamco to an extra tropical low, and
issued their final advisory. The JMA continued to monitor it as a
severe tropical storm until early the next day when they downgraded
it to an extratropical low as it approached the international
dateline.
Vamco then crossed the International
Dateline and was monitored as an extratropical low until late on
August 28 when it dissipated to the south of Alaska
.
Tropical Depression
Early on
August 20, the JMA reported that a tropical depression of the
season had formed about 720 km (450 mi), to the southeast
of Okinawa
, Japan
.
The JTWC reported later that day that the depression had a broad
low level circulation center, with some weak convection over it and
was in a good environment to develop with fair sea surface
temperatures and low vertical wind shear. However early the next
day the JMA issued their final advisory on the depression as it was
downgraded to an low pressure area before the system dissipated
early on August 22.
Tropical Depression
Early on August 25, the JTWC reported that an area of convection
had persisted about 1000 km (630 mi) to the southeast of
Okinawa, Japan. The convection was moving over a broad and ill
defined low level circulation center, it was also located in an
area of low vertical wind shear. An upper level trough was
approaching the system from the northwest and was hindering
outflow, bringing cooler and drier air to the disturbance. Later
that day the JMA then reported that the disturbance had developed
into a tropical depression, before early the next morning the JTWC
reported that the depression had dissipated. However the JMA
continued to issue advisories on the depression, until later that
day when the JMA issued their final warning on the
depression.
Severe Tropical Storm Krovanh
On August
27, JMA reported that an area of convectional cloudiness associated
with monsoon through formed about 720 km (450 mi), to the
southeast of Iwo
To, Japan. Satellite imagery shows that
convective bands is starting to wrap into the Low Level Circulation
Centre (LLCC) and the system is located in moderate vertical
windshear and favorable area. Early of August 28, the system is
showing a good development LLCC then the JMA upgraded the system
into a minor tropical depression. While JTWC issued a Tropical
Cyclone Formation Alert (TCFA) on the system then after several
hours, they upgraded it into a tropical depression. In the evening
of that day, the depression rapidly intensified into a tropical
storm due to hot water temperatures and associated with Tropical
Upper Tropospheric Trough (TUTT) that located in the northeast of
the tropical storm, whilst JMA assigned the name Krovanh. While
JTWC also upgraded the depression into a tropical storm. Early of
August 30, JMA upgraded Krovanh into a severe tropical storm. On
the next day, Krovanh weakened into a tropical storm due to its
interaction with the frontal system and the eye was quickly become
visible. On September 1, both JMA and JTWC issued their final
warning on Krovanh. The remnants of the storm was absorbed by a
frontal system and dissipated later that day.
Tropical Depression 02C
Late on August 29, the JMA started to issue warnings on Tropical
Depression 02C as it was expected to cross the International
Dateline and move into the Western Pacific within 24 hours and
intensify into a Tropical Storm. Early the next day the depression
crossed the dateline into an area of strong vertical windshear.
Thus the tropical depression began to weaken with the low level
circulation center becoming fully exposed and sheared as a result
the JTWC issued their final advisory later that day. However the
JMA continued to issue advisories on the depression until early on
September 2, they downgraded the depression to an area of low
pressure and issued their final advisory.
Severe Tropical Storm Dujuan (Labuyo)
On August
28, an area of convectional cloudiness associated with monsoon
trough formed about (620 miles) 1000 km southwest of Okinawa, Japan. Satellite imagery revealed that a
partial Low Level Circulation Centre was exposed with an
anticyclone was providing good outflow that located to the
northwest of the system. Early of September 1, the system showed a
more defined LLCC and moving through warm waters, whilst JMA
upgraded the system to a tropical depression. On September 2, the
depression entered in the Philippine area of responsibility and
PAGASA assigned it a local name
Labuyo. On the next day,
PAGASA upgraded Labuyo into a tropical storm while JTWC issued a
TCFA. Later that day, JTWC designated it is tropical depression
13W. Early next day, JMA upgraded the depression intensified into a
tropical storm and assigned it a international name
Dujuan, while JTWC then also upgraded Dujuan as a tropical
storm. On September 5, JMA upgraded Dujuan into a severe tropical
storm. Later that day, PAGASA issued their final warning on Labuyo
as the storm moved out on their area of responsibility. Early of
September 8, JTWC downgraded Dujuan into a tropical depression.
After several hours of that same day, JTWC amended a issue that
Dujuan was intensified again into a tropical storm.
Tropical Depression
Early on September 1, the JTWC reported that an area of
convectional cloudiness had persisted in an area of low pressure
vertical windshear about 500 km (305 mi) to the northwest
of Manila in the Philippines. The system had a fully exposed low
level circulation center with small pockets of convection confined
to the western edge of the cyclone. During the next couple of days
the disturbance developed further with deep convection
consolidating near the low level circulation center before being
designated as a tropical depression by the JMA and had a
Tropical Cyclone Formation
Alert issued by the JTWC early on September 3. Later the next
day, it made a direct hit on Đà Nẵng, Quảng Nam and Quảng Ngãi,
Vietnam and after several hours. Later that day, JTWC had cancelled
TCFA.
It
had re-emerged back into the South China Sea and remained nearly stationary.
At least six people have been killed and five others were injured
by the depression throughout Vietnam. Rainfall from the storm
exceeded , triggering widespread flash flooding. Sixty-one tons of
fish were swept away during the floods and 8,700 hectares of rice
were destroyed.
Tropical Storm Mujigae (Maring)
On
September 6, an area of convection cloudiness associated with the
monsoon through was formed about 305 km (200 mi) to the
northwest of Manila,
Philippines. Satellite imagery shows that a mid — level
convection consolidating in over a developing Low Level Circulation
Centre (LLCC). In additionally, there is a westerly wind burst that
located three to five degrees of the system and located in moderate
vertical wind shear. Late of September 8, the system is moving
northwest and also in hot water temperatures, whilst the JMA
upgraded the system into a tropical depression. Also, on the
evening, PAGASA declared the system as a tropical depression and
assigned its local name,
Maring. While JTWC issued a
Tropical Cyclone Formation Alert (TCFA). Early of the next day,
JTWC upgraded the system into a tropical depression due to its LLCC
is partially exposed. In the evening, as the depression is moving
northwestward, PAGASA issued its final advisory as Maring moves out
in their area of responsibility.
Typhoon Koppu (Nando)
On
September 9, an area of convectional cloudiness associated with the
monsoon trough formed 370 km (250 mi) to the northwest of
Palau. Satellite imagery showed that a
consolidating Low Level Circulation Centre (LLCC) with convection
had started to develop and was wrapping toward the center. On
September 11, the LLCC started to show improvement and was under
moderate vertical shear with good westward outflow, but the JMA
still upgraded the system to a minor tropical depression. Early of
September 12, PAGASA upgraded the system in their responsibility
and assigned its local name,
Nando.
At 1500 UTC, PAGASA
reported that the depression made its landfall over northern
Palanan,
Isabela
of the Philippines. However both JMA and JTWC reported that the
depression didn't made its landfall but only crossed the Luzon
straight. Early of the next day, JTWC upgraded the system
into a tropical depression. Early of September 13, both JMA JTWC
upgraded the system as a tropical storm and assigned its
international name,
Koppu. In the afternoon, JMA reported
that Koppu intensified into a severe tropical storm. On the 14th,
the JMA reported that Koppu had intensified to a minimal typhoon,
but the JTWC still kept Koppu as a tropical storm for the next few
hours but later acknowledging the intensification and upgraded
Koppu to a minimal typhoon. But the JTWC issued their final
advisory early on September 15, as Koppu was moving over land, and
was expected to dissipate quickly.
In Luzon, a 48 hour rainfall was experienced.
In Visayas
and Mindanao, a 24 hour rainfall was also experienced due to
Nando's enhancing southwest monsoon. About 10 provinces were
raised in signal warning no.1 from September 12 – September 13.
Nando had
triggered landslides resulting road closures and evacuations of
some residents in Kalinga province
. The storm then caused major flood in Luoding, People's
Republic of China
.
Typhoon Choi-wan
Typhoon Choi-wan formed as weak tropical disturbance early on
September 11, 2009, about 1100 kilometers (700 mi) to the east
of Guam. During that day the disturbance rapidly developed and was
designated as a tropical depression early the next day by both the
JMA and the JTWC before intensifying further and being named as
Tropical Storm Choi-wan on September 12. During September 13,
Choi-wan's rapid intensification slowed down barely intensifying
into a severe tropical storm, before early the next day it was
upgraded to a typhoon and rapidly intensified during the day to
become a Category 4-equivalent typhoon. Choi-wan then intensified
further during September 15, as it moved through the Northern
Marina Islands with the Japan Meteorological Agency reporting peak
10 minute sustained wind speeds of 195 km/h (120 mph),
whilst the Joint Typhoon Warning Center reported 1-minute peak wind
speeds of 260 km/h (160 mph) which made it a category
5-equivalent typhoon.
With the help of excellent poleward outflow and high ocean heat
content, Choi-wan remained at its peak intensity until early on
September 17 when deep convection started to erode in the
northwestern quadrant as the
tropical upper tropospheric
trough cell to the northwest was no longer providing good
outflow. Choi-wan was then downgraded to a typhoon by the JTWC as
it started to undergo an eyewall replacement cycle, with the JTWC
reporting a secondary peak intensity of 150 km/h,
(90 mph), during the next day. During September 19, Choi-wan
rapidly weakened, as it moved into an unfavorable environment with
higher amounts of vertical wind shear, causing the storm's deep
convection to erode. As a result of this and dry latitude air
wrapping into the low level circulation center, the JTWC decided to
downgrade Choi-wan to an extratropical system and released their
final advisory early the next day, before the JMA followed suit
later that day.
Despite the intensity of Choi-wan when it passed over the Northern
Marina Islands, there was no casualties reported.
It was determined
afterwards by the US Navy that the whole
island of Alamagan
was uninhabitable, with all but one of the
structures, a facility for laboratory and research, completely
destroyed and most of the islands' trees downed. As a result
it was determined that all of the residents of Alamagan and Agrihan
needed to be completely evacuated to Saipan.
Tropical Depression
Early on September 23, the JMA reported that a Tropical Depression
had formed about 1145 km (710 miles) to the southeast of
Tokyo, Japan. During that day the depression moved towards the
northwest before the JTWC reported early the next morning that the
depression was a vertically stacked upper level low with a closed
circulation which was transitioning into a tropical system with a
warm core. However as the system lacked any central convection and
upper level conditions deteriorated as a longwave trough passed by
the system it was reported as dissipated early on September 25 by
the JTWC, however the JMA continued to monitor the system until
early the next day before issuing their final advisory on the
depression.
Typhoon Ketsana (Ondoy)
On
September 22, an area of convectional cloudiness associated with
the monsoon trough had formed about 720 km (450 mi), to
the east of Manila,
Philippines. Satellite imagery showed deep convection
starting to consolidate about an LLCC. In the afternoon of the next
day, the system started showing good outflow in LLCC and was moving
through moderate vertical shear whilst the JMA upgraded the system
to a tropical depression. On the evening of the same day, the JMA
reported that the depression weakened into an area of low pressure.
In the afternoon of September 24, the JMA reported that the system
was organizing again and was upgraded to a tropical depression
again, while the PAGASA also upgraded the system to a tropical
depression and assigned it the local name
Ondoy. On the
same day, the JTWC also issued a TCFA on the system. Early the next
day, the JTWC upgraded the system to a tropical depression again.
In the evening, the PAGASA reported that Ondoy intensified into a
tropical storm. Early on September 26, the JTWC upgraded the
depression to a tropical storm as well. At the same time, JMA also
upgraded it as a tropical storm and assigned it the international
designated name
Ketsana.
In the Philippines, the whole archipelago experienced a torrential
rain starting on September 23. more than 30 areas in Luzon,
including Metro Manila, were placed under storm alerts as tropical
storm "Ondoy" accelerated further and moved closer to Central
Luzon. On Bicol region, ferry passengers were suspended during
September 25 through the next day due to high waves and heavy rains
that were brought by Ketsana into the region affecting about 2000
people. In the Manila International Airport, 13 flights were
cancelled due to Ketsana making landfall. Some universities in
Manila suspended their classes due to severe flooding in some areas
and heavy rainfall.
In addition, the PAGASA also advised residents living in low-lying
areas and near mountain slopes in areas affected by the Southwest
Monsoon and those under signals #1 and #2 (see below) are alerted
against possible flashfloods and landslides. Also, PAGASA has
alerted the National Disaster Coordinating Council (NDCC) for
possible flashfloods and landslides in the affected areas,
particularly in Laguna, Quezon, Zambales, Pampanga and Bataan
provinces. Philippine Coast Guard commandant Admiral Wilfredo
Tamayo also reminded owners of seacraft of a guideline barring
travel for seacraft weighing 1,000 tons or less.
A total of 25
province
and Metro Manila were placed under
state of calamity, with Metro Manila
experiencing a record amount of rainfall in 42 years, with rain
falling between 8:00 a.m. and 2:00 p.m. of September 26 pegged at
341mm, over the record established in June 1967 at 334mm.
Tropical Depression 18W
The JTWC
reported on September 24 that an area of convection had persisted
about 725 km (450 mi) to the northeast of Pohnpei
. Deep convection had started to conslidate
and wrap around the low level circulation centre. By
September 26, the system had developed strong outflow and was
intensifying with the JMA reporting later that day that it had
become a Tropical Depression however the JTWC did not follow suit
until early the next day when they assigned the designation of 18W
to the depression. During the next couple of days very little
intensification took place as convection barely deepened around the
low-level circulation center and in fact weakened due to the
precursor system to Typhoon Parma was developing to the southeast
of 18W. However early on September 29, the JTWC upgraded the
depression to a tropical storm with peak windspeeds of 65 km/h
(40 mph) whilst the JMA reported peak windspeeds of
55 km/h (35 mph). As 18W approached Guam, the system
became severely disrupted after interaction with what were to
become Typhoons Melor and Parma. As it passed near the island, the
storm rapidly dissipated, first weakening to a depression and then
as it lost its low-level circulation centre it was no longer
considered a tropical cyclone and thus the final warnings from the
JTWC and the JMA were issued.
Despite a state of emergency being declared by the Governor of Guam
before the depression affected Guam on September 29, it had very
little imapct on Guam. With only increased winds and moderate
rainfall reported. All flights in and out of Guam were cancelled
until the storm had passed. Five ships and a submarine from the
United States Navy moved out to
sea to avoid the storm; however, one submarine was unable to leave
and remained at port during the storm.
Typhoon Parma (Pepeng)
Early on
September 25, an area of convectional cloudiness associated with
the monsoon through formed 410 km (280 mi) to the
southeast of Palau.
Satellite imagery showed a consolidating Low Level Circulation
Centre. On September 27, the system began improving and showing a
partial LLCC due to favorable conditions and was also located under
moderate vertical wind shear, whilst the JMA upgraded the system
into a tropical depression. On the evening of that day, the JTWC
issued a Tropical Cyclone Formation Alert. On the next day, JMA
reported that the depression had intensified into a tropical storm,
submitting its international designated name,
Parma. Also,
on the same day, JTWC upgraded it to a tropical depression. On the
next day, JTWC again upgraded the depression into a tropical storm.
And, by early September 30, due to the storm moving through warm
water temperatures, the JTWC and JMA upgraded it to a Category 1
typhoon. Satellite imagery also began showing that an eye wall
structure had formed. Intensification continued into in the morning
of the next day, reaching Category 3 status. Then, after four
hours, Parma rapidly strengthened to a Category 4 super typhoon,
reaching its peak strength. Different weather bureaus forecasted
that Parma would intensify into a Category 5 super typhoon,
however, it weakened in the afternoon of October 1 as the eye of
Parma began to degrade due to its movement into unfavorable
conditions.
Parma continued to slightly weaken while
moving through the area of Cagayan, then by midday of October 3, it was downgraded
into a Category 3-equivalent typhoon. Before it made
landfall over northern Cagayan at 3:00 pm PST(07:00 UTC), it
weakened into a Category 2 typhoon. Parma crossed northern Luzon
over 12 hours, during which the typhoon weakened into a category 1
equivalent typhoon.
PAGASA reported that the typhoon was moving
almost stationary in their area of responsibility due to
interaction with Typhoon Melor and a ridge of high pressure area
over mainland China
. At
the same time, JTWC downgraded Parma into a tropical storm while
the JMA downgraded it into a severe tropical storm. Early the next
day, satellite imagery revealed that Parma had an eye center but no
convectional cloudiness due to high pressure. Intensification was
unlikely because of unfavorable environment conditions and
interaction with Typhoon Melor. On October 7, Parma weakens into a
tropical depression while it is crossing the northern Luzon and
moving out into the Philippine area of responsibility, then PAGASA
issued their final warning on Parma. On the next day, both JMA and
JTWC reported that Parma re intensified into a tropical storm while
it is on south China sea. Intensification is almost difficult due
to moderate vertical wind shear.
Then by late of October 12, it made its
fourth landfall over Hainan Island in
China. Then, In early of October 14, Parma was downgraded by
JMA to a tropical depression due lack of convection.
Then by the afternoon
of that day, it made its fifth landfall over the coastline of
Vietnam
. In the evening, JMA reported that Parma
weakens into an area of low pressure, becoming the agency issues
their final advisory. However, JTWC still considered Parma as a
tropical storm.
On October 6, at 11:00 pm PST (15:00 UTC), Parma made its second
landfall over Ilocos Norte. In the afternoon of the next day,
PAGASA reported that Parma weakened into a tropical depression near
the Isabela area, while both JMA and JTWC still classified Parma as
a tropical storm. In the morning of October 8, it emerged back into
waters near Isabela.
After four hours, Parma made its third
landfall in Cagayan. The next day, Parma crossed Northern Luzon
for the second time.
Then by the afternoon of that day, Parma
exited La
Union and emerged back into the South China Sea.
At the same time, JTWC upgraded it into a tropical storm. On
October 10, the JTWC downgraded it back to a tropical depression
and once more upgraded it into a tropical storm.
On October 12 it made
landfall on the island of Hainan.
Typhoon Melor (Quedan)
On
September 28, an area of convectional cloudiness formed 370 km
(250 mi) to the northeast of Pohnpei. Satellite imagery showed a Low Level
Circulation Centre had begun to form. On the evening of September
28, due to a TUTT that was providing good outflow for the system
and low level vertical wind shear with a favorable environment, the
JTWC issued a Tropical Cyclone Formation Alert. Early on September
29, both JMA and JTWC upgraded the system into a tropical
depression. Early on September 30, JMA reported that the depression
had intensified into a tropical storm and assigned its
international designated name,
Melor. At the same time
JTWC also classified the depression as a tropical storm. Early on
October 1, Melor intensified further from a severe tropical storm
into a typhoon. Intensification continued, and by the afternoon of
the same day the JTWC reported that Melor had intensified into a
Category 1-equivalent typhoon.
In just four hours, it intensified rapidly
to a Category 3-equivalent typhoon, and continued to track towards
northeast Luzon.
Early on October 2, it strengthened to a Category 4-equivalent
typhoon. After levelling out in intensity, it strengthened again on
October 3. Early October 4, JTWC reported that Melor had
intensified to a Category-5 equivalent super typhoon, with JMA
reporting a central pressure of 910 hPa and winds of 205 km/h.
On October 5, PAGASA allocated the name Quedan to the typhoon as
the storm moved into Philippine's area of responsibility. By the
midday of October 8, Melor made landfall on Japan. After landfall,
JMA downgraded Melor into a severe tropical storm, while the JTWC
downgraded it into an extratropical storm. Late on October 9, the
remains of Typhoon Melor were absorbed by a newly formed
low-pressure system. Damage is currently estimated at about $1.5
billion (2009 USD).
Tropical Storm Nepartak
On
October 6, an area of convectional cloudiness associated with the
monsoon trough formed 500 km (305 mi) to the southwest of
Saipan
.
Satellite imagery showed a consolidating Low Level Circulation
Center with formative convective banding and deep convection over
the northern semi-circle. During in the morning of October 8, the
system started to move northwest and it's LLCC rapidly became well
defined due to favorable conditions. The JMA then upgraded it to a
tropical depression, and the JTWC issued a TCFA on the system, as
it had started to become better defined. Then in the evening of
that day, it was upgraded into a tropical depression by the JTWC.
On October 9, the JMA upgraded it to a tropical storm and assigned
its international name
Nepartak. After the JMA upgraded it
to a tropical storm, it slowly intensified to a peak intensity of
50 mph (85 km/h), but dissipated on October 14, because
the polar jet stream had torn apart the storm.
Typhoon Lupit (Ramil)
Early on October 13, the JTWC reported that an area of convection
had persisted about 380 nm to the northwest of Kwajalein. The
convection was disorganised but was starting to consolidate around
a broad low level circulation center within a favourable
environment to develop further with good vertical windshear and
favourable sea surface temperatures. The disturbance rapidly
developed throughout that day with a Tropical Cyclone Formation
Alert issued later that day by the JTWC before advisories were
initiated early the next day by the JMA and the JTWC who designated
it as Tropical Depression 22W before the JTWC reported that the
depression had intensified into a weak tropical storm. On October
15, JMA upgraded it to a Tropical Storm with the name
Lupit. On the afternoon of next day, JTWC reported that
Lupit strengthened into a Category 1 typhoon. That evening, PAGASA
started issuing warnings on Lupit as it entered into their area of
responsibility and assigned its local name,
Ramil. At the
same time JMA also upgraded Lupit into a typhoon. Intensification
continued due to favorable conditions and hot water conditions,
then by October 17, it rapidly intensified into a Category
3-equivalent typhoon. In the morning of the next day, it
strengthened into a Category 4 typhoon, then strengthened further
to Super Typhoon classification. On October 20, Lupit weakened to a
minimal typhoon. By the 24th, dry air entrainment and an
unfavorable environment had weakened Lupit further to a strong
tropical storm, and caused the storm to change track from its
westward drift to accelerate northeastward. Later that day, JTWC
and PAGASA issued their final warning as Lupit was beginning
extratropical transition. However, the JMA continued to issue
warnings on Lupit until early on October 27.
Tropical Depression
Late on October 15, the JTWC reported that an area of convection
had persisted about 780 km (485 mi) to the southeast of
Hue, Vietnam. Convection was forming and wrapping into the low
level circulation center and was moving into a favourable
environment to develop with low vertical windshear and warm sea
surface temperatures. It was then designated as a Tropical
Depression by the JMA early the next morning as the low level
circulation center was becoming exposed due to the high amounts of
vertical windshear. A Tropical Cyclone Formation Alert was issued
early on October 17 by the JTWC as the vertical windshear
decreased, despite the low level circulation center being fully
exposed. The Depression remained weak with the tropical cyclone
formation alert being cancelled during October 19 before the
depression dissipated on October 20.
Typhoon Mirinae (Santi)
JMA upgraded a Tropical Depression to Tropical Storm Mirinae on
October 27, and it rapidly strengthened
to a Typhoon, to a peak of 105-110 mph. It did not strengthen much
further, due to wind shear and its fast movement of the typhoon.
PAGASA allocated the name Santi to the system the next day, as the
storm had entered their area of responsibility. Then Mirinae
crossed the Philippines, causing it to rapidly deorganize and was
downgraded from a Category 2 Typhoon, to a tropical storm in one
advisory. It then crossed into the South China Sea, and slowly, but
steadily strengthened until it was very close to Vietnam. Where it
rapidly intensified to a Typhoon again. It made landfall and
rapidly weakened.
Tropical Depression Tino
Late on October 31, the JTWC reported that an area of convection
had started to develop over a well defined low level circulation
center in an area of moderate vertical windshear about 1220 km
(760 mi), to the east of Manila, Philippines. By the next
morning, the JMA reported that it had become a weak tropical
depression before later that day, the JTWC issued a TCFA on the
depression as the low level circulation center's organization had
improved. By the 2nd, the depression had entered PAGASA's area of
responsibility, and they soon assigned its local name of
Tino and Tropical Depression 24W by JTWC. The depression's
potential organization was short lived, and by November 3, the
system's center had become fully exposed, and it degenerated to a
remnant low later that day.
Tropical Depression 25W
Early on November 3, the JTWC reported that an area of convection
had persisted in a moonsoon trough about 440 nm to the
southeast of Pohnpei. The convection was poorly organised and was
located in a moonsoon trough amidst a weak and elongated circlation
with weak mid level turning. However environmental conditions were
not favourable for the disturbance to develop as it was located in
an area of moderate vertical windshear. Over the next few days the
disturbances gradually developed a low level circulation center and
as a result was designated as a tropical depression early on
November 7 by both the JMA and the JTWC.
Tropical Depression Urduja
On
November 23, PAGASA announced that a low pressure area east of
Mindanao had developed into a Tropical Depression and had
been named "Urduja". The same day JTWC designated the
tropical depression as 27W. Early Of November 25, the depression
has weakened into an area of low pressure. The remants of Urduja
were absorbed into Typhoon Nida during November 25 and 26.In
Eastern Visayas, 1, 519 passengers were stranded, 719 in Western
Visayas, 399 in Bicol and 185 in Southern Luzon due to Urduja.
[733897] In all, four people were killed by
Urduja, three due to a landslide and one from electrocution.
Typhoon Nida
Early on November 21 the JTWC reported that an area of convection
had persisted within a monsoon trough about 880 km,
(545 mi) to the southeast of Guam. At this time the system was
moving around the subtropical ridge of pressure, with an
anticyclone over the cyclone helping the convection to consolidate
over a broad and elongated low level circulation center which was
located in an area of minimal vertical wind shear. Later that
morning a Tropical Cyclone Formation Alert was released as deep
convection increased in organization with multiple bands of
convection starting to wrap into the developing low level
circulation center. The system was then declared as a tropical
depression by the JMA later that day before the JTWC followed suit
early the next day, who assigned the designation of 26W to the
depression. On November 23, the JTWC upgraded the system to a
tropical storm, and JMA followed suit allocating the name Nida.
Later the next day, JTWC reported that Nida rapidly intensified
into a the equivalent of a category 1 typhoon. The next day JMA
upgraded Nida to a Severe Tropical Storm Intensification was
anticipated until in the afternoon of November 25, then JTWC
reported that Nida intensified from category 2 to a category 4
super typhoon equivalent. While JMA also upgraded it to typhoon
status. At the same time an eye wall structure had formed. During
the evening of November 25, Nida further intensified into an
extremely intense Category 5 equivalent super typhoon, according to
the JTWC, attaining winds of 295 km/h (185 mph) as it
moved north west past Guam. Nida became the first storm of this
intensity in the basin since
Typhoon Chaba in
2004, and the first anywhere in the world since
Hurricane Wilma in 2005. Additionally, the
JMA reported that the barometric pressure had decreased to
905 mbar, ranking Nida as the strongest storm to form during
2009 worldwide, only slightly eclipsing
Hurricane Rick's intensity. Later,
Nida was downgraded to a category 4 equivalent, due to an eyewall
replacement cycle, but shortly regained strength, and on November
28, Nida re-intensified to a Category 5 typhoon. It later stalled
and remained stationary for some time while gradually weakening
into a Category 1 typhoon by November 30.In addition, Nida now
ranks among the strongest storms ever to develop in the month of
November.
Tropical Depression
On November 22, the JTWC reported that an area of deep convection
had persisted about 530 km (330 mi) to the northeast of
Singapore. Deep convection was flaring over a loosely defined low
level circulation centre. Levels of vertical wind shear were
unfavourable for development. Early the next day, as the low level
circulation centre was improving very quickly in an area of
vertical wind shear, a Tropical Cyclone Formation Alert was
released by the JTWC, before early on November 24; the JMA reported
that the disturbance had become a tropical depression. However the
JTWC reported early the next day the convection had become
disorganised as the environment around the depression became less
favourable, with increasing vertical wind shear. The JMA then
downgraded the depression to a low pressure area early on November
26 before it dissipated later that day.
Storm Names
Western North Pacific tropical cyclones are named by the RSMC
Tokyo-Typhoon Center of the
Japan Meteorological Agency.
Names are selected from the following lists, there is no annual
list.
Names were contributed by 13 members of the
ESCAP/WMO Typhoon
Committee, except for Singapore
. The 13 nations or territories, along with
the Federated States of
Micronesia
, each submitted 10 names, which are used in
alphabetical order by the English name of the country. The
first storm and typhoon of the season was named Kujira. Storms were
named Molave and Mirinae for the first time, Molave having replaced
Imbudo in 2003 and Mirinae replacing
Sudal from 2004. Also, the name
Goni was corrected from
Koni.
