2006 Pacific typhoon season
Encyclopedia
The 2006 Pacific typhoon season had no official bounds; it ran year-round in 2006, but most tropical cyclone
s 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 2006 Pacific hurricane season
. Tropical Storms formed in the entire West Pacific basin are assigned a name by the Japan Meteorological Agency
. Tropical depressions in this basin have the "W" suffix added to their number. 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.
ward. The Joint Typhoon Warning Center
released a Tropical Cyclone Formation Alert
on May 8, shortly before it upgraded the storm to a Tropical Depression. It became a tropical storm on May 9. The name "Chanchu" was submitted by Macau
and means pearl
. The JTWC then upgraded it to a typhoon on May 10. The storm maintained a westerly track and made two landfalls in the Philippines
, causing 32 deaths in the country and $1.9 million in damage, much of it to agriculture.
After Chanchu left the Philippines, the JMA upgraded it to a typhoon. Chanchu turned to the north in the South China Sea
and affected hundreds of Vietnam
ese fishermen. Then, it became a super typhoon, only the second ever recorded in the South China Sea, but was one for only less than a day. The only other super typhoon to form in the South China Sea in recorded history is Ryan
in 1995. Chanchu is also the most intense typhoon on Hong Kong Observatory
's record to enter the South China Sea in May. Chanchu necessitated the Strong Wind Signal no. 3
in both Hong Kong and Macau. It turned northeastward and made a final landfall along the southeastern seaboard of China on May 18 resulting in at least 25 deaths and a direct economic loss of 7 billion yuan
. Chanchu became extratropical later that day.
released a Tropical Cyclone Formation Alert
on June 25 as the system moved over the Philippines, and upgraded the system to Tropical Depression 03W the next day. The depression continued to organize as it moved away from the Philippines, and the JTWC upgraded it to Tropical Storm 03W on June 27. The Japan Meteorological Agency designated the storm as Tropical Storm Jelawat shortly after. The name Jelawat was submitted by Malaysia, and is a name for a type of carp
.
Jelawat moved generally northwestward over the South China Sea
during the next day, and weakened back to a tropical depression on June 28. The depression made landfall in southern China at 7:40 a.m. CST on June 29 and dissipated later that day.
The storm dropped heavy rainfall across southern China and Haikou
recorded a rainfall of 309.7 mm (12 inches) during the storm passage. A total of 8.6 inches (220 mm) rain fell in 16 hours in Kampung Bundu, Malaysia. The rainfall killed seven people and left one missing. The flooding from Jelawat ruined 200 square kilometres of farmland and destroyed 190 houses.
. The depression moved northwestward and was upgraded to Tropical Storm 04W by the JTWC on June 30. The JMA designated the storm Tropical Storm Ewiniar at around the same time. The name "Ewiniar" was submitted by the Federated States of Micronesia
, and refers to a traditional storm god of Chuuk
.
Ewiniar was responsible for at least 30 deaths in China, which it brushed as a typhoon. The typhoon gradually weakened as it moved over colder waters, and made landfall in South Korea on July 10 as a severe tropical storm. As Ewiniar moved across the country, it passed within 30 miles (48.3 km) of Seoul
. No tropical cyclone had come that close to Seoul in recent years. The storm brought heavy rain that triggered floods and mudslides in the southern part of the country, killing at least six people. Ewiniar became extratropical over the Sea of Japan
on the same day.
developed sufficient convection to be designated a tropical depression on July 8. The depression strengthened into a tropical storm the next day, and was designated Tropical Storm Bilis by the JMA. The word "Bilis", submitted by the Philippines
, means speed or swiftness. PAGASA operationally treated this storm as a typhoon for a short time on July 13, but it officially remained a tropical storm as it moved west-northwestward toward Taiwan
. After moving over northern Taiwan, Bilis made landfall in Fujian
, China at 12:50 p.m. CST on July 14, weakening into a tropical depression inland the next day. JMA carried the system as a tropical depression until July 17. Bilis brought very heavy rain, widespread flooding, landslides, and strong winds to the Philippines
, Taiwan and areas of mainland China, causing 672 deaths and $4.4 billion (2006 USD
) in damage.
, it quickly strengthened to tropical storm strength the same day. On July 19, the storm was named Kaemi by the JMA. The correct name Gaemi was submitted by South Korea and is a Korean word for ant
. It strengthened into a severe tropical storm on July 20, and further deepened into a typhoon 24 hours later. Kaemi made landfall in Jinjiang
, Fujian
at 3:50 p.m. CST on July 25 as a minimal typhoon.
Heavy rainfall in Taiwan caused flooding and four minor injuries. Rain also fell heavily in the northern Philippines. The storm has also killed at least 32 people in China, while another 60 people are missing. Agricultural losses in Taiwan amounted to NT$73 million (US$2.2 million). Total damages from the storm amounted to $450 million.
as Tropical Depression Henry later on the same day that the JMA recognised it as a tropical depression on July 28. The JTWC upgraded this system to a tropical storm on the morning of August 1. Hong Kong Observatory
also did so and issued the Tropical Cyclone Signal No. 1 that same afternoon, and shortly after the JMA upgraded the system to Tropical Storm Prapiroon. The name Prapiroon was submitted by Thailand
and is the name of a Thai rain deity. The JMA upgraded the storm to a severe tropical storm on the morning of August 2. PAGASA ceased advisories on the storm shortly after as it moved out of its area of responsibility. The JTWC and the HKO upgraded Prapiroon to a typhoon at 3 a.m. UTC, while the JMA officially upgraded it to a typhoon at 12 p.m. UTC (8 p.m. HKT
). Prapiroon necessitated the first Tropical Cyclone Signal No. 8 in Macau this year. In Hong Kong, the flag raising ceremony at the Golden Bauhinia Square was cancelled due to strong wind. Prapiroon made landfall at 7:20 p.m. CST on August 3.
The strong winds due to the storm resulted in 70% of flights being cancelled, delayed or diverted in the Hong Kong International Airport
, the highest since the opening in 1999. However, the airport remained open throughout the storm passage and many flights successfully landed or took off on August 3. Inbound flights were rerouted to nearby airports and outbound flights were cancelled or postponed. On landfall in Guangdong
province, China, it forced the evacuation of some 660,000 people and caused an estimated 5.4 billion Chinese yuan worth of damage. 77 people were reported killed. It also affected Hunan
, Guangxi
and Hainan
. Prapiroon degenerated into an area of low pressure on August 6.
on August 4 and began issuing advisories. On August 5, the system had sufficiently strengthened to be named Tropical Storm Maria. The name Maria was submitted by the United States and is a common Chamorro feminine name
.
The JTWC designated this system as a tropical depression later that day before upgrading it to a tropical storm on August 6, while the JMA upgraded it to a severe tropical storm at 6 a.m. UTC. Maria turned to the north, threatening Japan's mainland. JTWC briefly upgraded Maria to a typhoon on August 7, but issued its final advisory two days later as it started to turn extratropical.
In their post season analyses, the JMA upgraded the storm to a 80 mph (130 km/h) typhoon, while the JTWC downgraded it to a 70 mph (110 km/h) tropical storm.
late on August 4 UTC. The JMA designated it as such at 12 a.m. UTC August 5. Nine hours later, the JTWC upgraded Tropical Depression 08W to a tropical storm, three hours before the JMA named it Saomai. The name is from the Vietnamese
"sao Mai", meaning "Morning Star", a reference to the planet Venus
.
The JTWC designated it a typhoon at 3 p.m. UTC August 6. The JMA upgraded Saomai to a Severe Tropical Storm at 6 p.m. UTC, and as it continued to strengthen, it was upgraded to a typhoon just 12 hours later. Saomai passed into the Area of Responsibility of PAGASA on August 8 and was named Typhoon Juan by PAGASA. On August 8, the storm underwent explosive development, and by August 9 it had become a Category 5-equivalent super typhoon.
Saomai made landfall in Zhejiang
, China on August 10 with maximum sustained winds of 115 knots (1-minute mean), stronger than Chanchu earlier this season. Saomai was responsible for at least 458 deaths, mostly in China, and $2.5 billion (2006 USD) in damage.
and bring rains to the Philippines
. Around 1800 UTC, the JTWC declared that the system had developed into a tropical depression and gave it the number 10W. JMA upgraded it to Tropical Storm Bopha on August 6. The name Bopha was submitted by Cambodia
and is a flower and girls' name. Around this time, the JTWC also upgraded the system to a tropical storm.
The JTWC recognised its existence as a tropical depression at 9 a.m. UTC the same day before upgrading it to a tropical storm at 3 p.m. UTC. The JMA then upgraded it to a severe tropical storm as it slowly churned westwards at 12 a.m. UTC August 7 before downgrading it 18 hours later. Bopha unexpectedly restrengthened into a severe tropical storm at 3 a.m. UTC August 8, before weakening back to a tropical storm at 12 p.m. UTC.
Bopha later made landfall on Taiwan
at about 2 a.m. local time on August 9. At this time, the JTWC reported that Bopha attained winds of 100 km/h (65 mph). Tropical Storm Bopha then weakened into a tropical depression before degenerating into a remnant low on August 10.
The outer bands
of Tropical Storm Bopha produced heavy rains over northern Luzon
, triggering flooding that destroyed 1,200 homes and killed seven people. Two of the fatalities occurred after a home was destroyed by a landslide in Kalinga Province
. The landslide damaged 20 other homes, a church and a school.
As Severe Tropical Storm Bopha approached the island on August 8, the meteorological agency in Taiwan issued land and sea warnings for most of the region. Residents were warned about the possibility of torrential rains, flooding and mudslides. Although the storm was forecast to directly impact the island, all businesses remained open and schools were not closed. In Hong Kong
, the Hong Kong Observatory
issued Standby Signal number one as Bopha came within 800 km (497.1 mi) of the city on August 9. This signal was later discontinued on August 11.
Between August 9 and 10, the remnants of Bopha produced moderate rainfall around Hong Kong, peaking at 45.6 mm (1.8 in). Wind gusts up to 110 km/h (70 mph) were also produced by the storm throughout the city. A storm surge
of 0.48 m (1.6 ft) was recorded in Tai Po Kau on August 8.
on August 12. Early on August 13, as it moved to the north-northwest, the JTWC upgraded it to a tropical storm. The JMA named it Wukong later that day. Wukong
was submitted by People's Republic of China, and it is the name of a character in a Chinese epic. Wukong absorbed Tropical Storm Sonamu shortly before landfall in Japan. Wukong then stalled over Kyūshū
, before starting to jog to the north-northwest. It was downgraded to a tropical depression on August 20.
In post-operational analysis by the JMA, Wukong was upgraded to a severe tropical storm.
, and was named Katring by PAGASA and Sonamu by JMA. The name Sonamu was submitted by DPR Korea
and signifies a pine tree
. Sonamu began interacting with nearby Tropical Storm Wukong on August 15, with the outflow from the stronger Wukong producing unfavourable shear over the cyclone. The JMA declared the system a tropical depression and stopped issuing advisories on August 16. The JTWC followed shortly after.
and entered the Japan Meteorological Agency
's Area of Responsibility at around 6 a.m. UTC, keeping its name while being reclassified as Typhoon Ioke. Ioke had earlier affected Johnston Atoll
. On August 31 the center of the typhoon passed very close to Wake Island
; 200 people were evacuated from there in advance of its approach. Typhoon Ioke then passed just to the northeast of Minami Torishima
, which had been evacuated ahead of the storm, but as a weakened Category 3-equivalent typhoon. Ioke then turned to the northeast, weakening as it started undergoing extratropical transition. The JMA released its final advisory on September 7. The extratropical
remnants of Ioke moved into the Bering Sea
where it caused severe beach erosion
along the western Alaskan coastline.
. Shanshan quickly strengthened and was upgraded into a severe tropical storm on September 11 and a typhoon later that day. Shanshan weakened slightly on September 14, but quickly restrengthened and reached Category 4 status on the JTWC's scale. Shanshan passed through the Yaeyama Islands
in the early morning hours of September 16. The JTWC reported that Shanshan was becoming extratropical
early on September 17, as the typhoon weakened to a tropical storm. The JTWC issued its final advisory on Shanshan later that day, and the JMA issued its last advisory on September 19, after Shanshan completed extratropical transition.
As Shanshan neared Taiwan
, the Central Weather Bureau
and local officials warned of flooding and high winds. However, as Shanshan turned towards Japan, all warnings were cancelled. South Korean forecasters also issued warnings ahead of an expected landfall, but this did not materialise. Ships were diverted as ports were closed as a precaution, while some other boats were forced to remain docked. In Japan, more than 90,000 people were evacuated from Yamaguchi Prefecture
.
Over 200 people were injured by Shanshan and 11 people were killed, mostly in Kyūshū
, although two deaths were reported in South Korea. A tornado spawned by the typhoon caused a train derailment in Nobeoka, Miyazaki
, Japan which caused no fatalities. Peak gusts on Iriomote
reached 155 mph (248 km/h). Flights and trains were delayed, while electricity was cut to about 3000 homes in Korea. A ship also sank off Ulleungdo
.
identified an area of disturbed weather northeast of Chuuk
on September 13. The disturbance drifted to the north over the next few days, gradually increasing in organization. The JTWC issued a Tropical Cyclone Formation Alert
on the disturbance on September 16, and both the JTWC and JMA declared the system a tropical depression early on September 17. The JMA upgraded it to Tropical Storm Yagi later that morning as it moved erratically through the open Pacific Ocean, and the JTWC soon followed suit. The name Yagi was submitted by Japan and means Capricornus
(goat). Yagi was upgraded to a severe tropical storm by the JMA on September 18, and the JTWC designated it a typhoon later that day. The JMA officially upgraded Yagi to typhoon status early on September 19. Yagi was upgraded briefly to a super typhoon by the JTWC from September 21 to September 22. On September 23, the JTWC reported that Yagi was becoming extratropical
as it continued to weaken, and issued its final warning the next day. The JMA downgraded Yagi to a severe tropical storm on September 24. It was the third tropical cyclone in the NW Pacific Basin that attained Category 5 status in 2006. It started to recurve near Chichi-jima
, and never affected major land areas. It became extratropical
near the western Aleutians on September 25.
(PAGASA) named an active low pressure area within its area of responsibility Tropical Depression Milenyo. After issuing a Tropical Cyclone Formation Alert
earlier, the Joint Typhoon Warning Center
issued its first warning on Tropical Depression 18W. On September 26 the Japan Meteorological Agency
named this system Xangsane. The name Xangsane was submitted by Laos
and means elephant
. Later that day, the JMA upgraded Xangsane to a severe tropical storm. A bout of rapid intensification followed, and all three agencies, the JMA, JTWC and PAGASA all upgraded the storm to a typhoon late on September 26 or early September 27. Xangsane made landfall on Samar Island
as a severe tropical storm.
The typhoon dropped heavy rainfall in the Philippines
. To avoid the storm, transit authorities kept seacraft at several ports in the archipelago, leaving over 3,500 passengers stranded. Xangsane also prompted Philippine officials to close all schools, financial markets, and government offices in and around Manila
. The typhoon killed over 200 people in the country, and produced strong winds and rainfall, downing power lines and causing mudflow
s. The strong winds caused moderate crop damage totaling to $7.2 million (2006 USD).
Xangsane made landfall as a typhoon near Hue
early on October 1. The JTWC stopped issuing advisories soon after, and the JMA downgraded it to a severe tropical storm. Xangsane killed 71 in Vietnam
.
developed into Tropical Depression 19W. The JMA had already been monitoring the storm. It was named Neneng by PAGASA, and later that evening was upgraded to a tropical storm by the Philippine authorities. The JMA and JTWC both designated the storm a tropical storm the next day, and it was named Bebinca by the JMA. Bebinca is a type of Macanese
milk pudding
.
The JTWC downgraded it to a tropical depression briefly between October 4 and October 5 as wind shear took its toll. Its low-level circulation then became exposed with dry air entering the system, and both the JMA and JTWC declared the storm as a dissipating tropical depression on October 6. It soon became entrained within the circulation of a storm-force extratropical low
, which swept across the Honshū
coastal waters and led to 33 people dead or missing. It was upgraded to a severe tropical storm in post analysis.
in high sea-surface temperatures gained enough convection and was designated Tropical Storm Rumbia by the JMA, although the JTWC had not even carried it as a tropical depression. Rumbia is a type of palm tree that yields sago
. Later that day, the JTWC issued a Tropical Cyclone Formation Alert
, and began warnings on Tropical Depression 20W the next day. Rumbia slowly began to intensify while moving to the northwest, but on October 6 its low-level circulation became fully exposed, and the JTWC issued a final warning. The JMA followed suit soon after. The remnants of Rumbia were later no longer distinct from the extratropical low associated with Bebinca.
, and is a traditional title for Pohnpei
chiefs. Soulik continued to intensify through October 10, and the JMA upgraded it to a severe tropical storm. Agrihan
was put under a tropical storm watch, which was later upgraded to a warning. In 18 hours on October 11, 8 inches (205 mm) of rain was reported on Pagan Island
. After days of gradual strengthening, it became a typhoon on October 12, stalling over Iwo Jima
. Soulik reached Category 2 status on the Saffir-Simpson Hurricane Scale
on October 13 before gradually weakening and moving northeastward rapidly as it became extratropical
.
on October 24. The disturbance moved west-northwestward over the next two days and gradually became better organized, and the Joint Typhoon Warning Center
issued a Tropical Cyclone Formation Alert
on the system on October 26. The system was designated Tropical Depression 22W by the JTWC later that day. The system continued to strengthen, and the JTWC upgraded it to a tropical storm on October 27. The Japan Meteorological Agency
later followed suit and designated the system Tropical Storm Cimaron. The name Cimaron was submitted by the Philippines
, and is a type of wild ox
. The system quickly intensified, and was upgraded to a severe tropical storm by the JMA later that day. The system continued its quick intensification and was upgraded to a typhoon by both the JTWC and JMA on October 28. Further intensification occurred overnight, and the typhoon had rapidly deepened
65 hPa
in 24 hours, from 985 hPa to 920 hPa, causing the JTWC to upgrade it to a 140-kt super typhoon at 9 a.m. UTC on October 29. It made landfall at about 12:30 p.m. UTC the same day on Northern Luzon
. There, especially in Isabela Province
, it lashed winds as much as 195 km/h and gusts as much as 230 km/h. Actually, all or parts of four provinces (Isabela, Quirino, Cagayan
and Aurora
) are declared under Signal #4 as the typhoon struck the island.
Cimaron then re-intensified after crossing the island, but not to its original strength, and was expected to curve towards Hainan, instead of moving towards Vietnam
as previously forecast. On November 1, the JTWC upgraded the typhoon back into a Category 3-equivalent storm, and forecast that it would make a direct impact on Hong Kong. However, prediction models showed conflicting forecasts, and Cimaron remained quasi-stationary and weakened to a severe tropical storm on November 2. Dry air entrainment caused further weakening, with the JTWC dropping it to a minimal tropical storm at 3 p.m. UTC the next day. It weakened further, upwelling itself. The JTWC issued its final warning at 3 p.m. UTC on November 4. The JMA continued advisories on Cimaron until 12 a.m. UTC on November 6, when it was downgraded to a weak tropical depression.
The typhoon killed at least 19 people, many of whom drowned, and left 15 missing in the northern Philippines. It also killed a woman and her child after both are hit by a sheet of galvanized iron in Dilasag, Aurora Province, serving as the first human casualties. Further casualties happened as the typhoon passed through Luzon. Despite these, however, classes in Metro Manila
were still not suspended. It also caused at least US$9 million in damage. 90% of the houses were damaged in a coastal town near where Cimaron made landfall. In the aftermath of the storm's passage across the Philippines, the Swedish International Development Cooperation Agency
contributed 2.5 million Swedish krona
(US$350,000) to aid efforts.
on October 31, and moved west-northwestward over the next week without any increase in organization due to an unfavorable environment, until November 6, when it encountered more favorable conditions, and the Japan Meteorological Agency
declared it a tropical depression on November 8. The Joint Typhoon Warning Center
issued a Tropical Cyclone Formation Alert
on the system later that day, and PAGASA
named the system Tropical Depression Queenie shortly after. The JTWC classified it as Tropical Depression 23W early on November 9. According to the JTWC, lack of equatorial outflow prevented rapid intensification of the system. Later that day at 12 p.m. UTC, the JMA upgraded it to a tropical storm named it Chebi. The name Jebi, the correct spelling means swallow
in Korean. The JTWC and PAGASA both followed suit later that day. Early on November 10, the JMA upgraded Chebi to a severe tropical storm as it continued to move west towards the Philippines
, following a similar track as Typhoon Cimaron earlier in the season.
Just hours later, the JMA upgraded Chebi from severe tropical storm with 10-minute sustained winds of 55 knots to a typhoon with winds of 95 knots, with a pressure decrease of 40 hPa
over three hours. The JTWC followed suit, upping Chebi from a tropical storm with 1-minute sustained winds of 55 knots to a Category 4-equivalent
typhoon at 9 a.m. UTC. PAGASA raised Public Storm Warning Signal #4 for three provinces in Luzon
, making Chebi the second storm (Typhoon Cimaron served as the first one that year.) in as many weeks to force a Signal #4. After rapidly deepening
, Chebi weakened as it approached the Philippines. It made its first landfall near Casiguran, Aurora
early on November 11, crossed the Lingayen Gulf
and its second landfall on Barangay
Lucap, Alaminos City
about 8 hours later.
Encountering dry air entrainment and increased vertical wind shear
in the South China Sea
, Chebi began to gradually weaken to a severe tropical storm on November 12. It continued to weaken, turning northwards towards Hainan
, and was downgraded to a tropical storm the next day. On November 14, the JMA issued its last advisory on the dissipating tropical depression. The JTWC issued its final warning later that same day as Chebi dissipated under the strong shear.
All told, the typhoon caused further casualties as well as damage caused by the earlier Typhoon Cimaron. After passing through Luzon, it left 1 dead and 10 injured. In Aurora Province
, it caused floods, cutting the province's road system, as well as zero visibility, further isolating it from relief efforts.
on November 24. Wind shear
near the disturbance soon decreased, allowing the depression to organize a little. It was designated a tropical depression by Japan Meteorological Agency
on November 25, and later that day the Joint Typhoon Warning Center
started issuing warnings on the system as it moved west-northwest towards Yap
. The depression strengthened because it was in an area of high sea-surface temperatures, and there were distinct cloud features of anticyclonic
outflow, according to the JMA. It was upgraded to a tropical storm on the afternoon of November 26 and named Durian. The name Durian refers to a fruit, "Durio zibethinus
", and was submitted to the naming list by Thailand
.
Moving west to west-northwestward, Durian intensified slowly. It became a severe tropical storm on November 27, and the next day it was named Reming by PAGASA
when it entered the Philippine Area of Responsibility. Later on November 28, both the JMA and JTWC upgraded it to a typhoon as it continued to track towards the Philippines
. A quick bout of intensification occurred on November 29, causing the JMA to upgrade the storm to 100 knots in wind intensity, and the JTWC to give it a Dvorak classification
of 6.5 (127 kt) in a satellite
fix. In 6 hours, Durian intensified from 90 kt 1-minute sustained winds to 125 kt winds. The JTWC then forecast a direct hit over Metro Manila
later that day when it upgraded the storm to a super typhoon. PAGASA raised Public Storm Warning Signal 4, its highest warning level, over Catanduanes
, Albay
, Camarines Norte
and Camarines Sur
. It was the third time in 2006, and the third time in a row, that PAGASA raised Signal #4. Durian began to weaken slightly as it approached land, undergoing an eyewall replacement cycle
, but quickly regained peak strength.
PAGASA claimed that the storm made landfall on the morning of November 30 over southern Catanduanes
, although the JMA and JTWC did not recognize this landfall. Durian then made another landfall after crossing the Lagonoy Gulf
in northeastern Albay
. After weakening due to interaction with land, Durian was downgraded back to a typhoon by the JTWC. The storm continued to move west, making landfalls on the Bondoc Peninsula
in Quezon
, on Marinduque
and finally on Oriental Mindoro
before exiting to the South China Sea
.
Encountering dry air entrainment and vertical wind shear
, Durian weakened slightly at first, but slowly began to reorganise and restrengthen as it neared Vietnam
. Durian began to turn slightly southwest towards Nha Trang
and Ho Chi Minh City
on December 3. Eventually, Durian began to weaken again, and by December 4, the JMA downgraded it to a severe tropical storm. The storm maintained intensity as it skirted the Vietnamese coast moving southwest. After a brief second stint at typhoon strength, Durian finally made landfall in Ben Tre Province
on December 5. The system rapidly weakened over land, and the JMA downgraded it to a tropical storm. The JMA and JTWC issued their final advisories later that day as Durian emerged into the Gulf of Thailand
as a weak tropical depression. The remnants of Durian then crossed the coast of southern Thailand
as it moved into the Bay of Bengal
.
The storm killed at least 720 in the Philippines
. The most damage occurred in Albay Province where the storm created mudslides of volcanic ash and boulders off Mayon Volcano
. The Padang barangay
of Legazpi City
was severely affected with a large portion of the town covered in mud up to houses' roofs. At least 81 people have died and 16 people are missing in Vietnam
from the storm.
southeast of Chuuk
. Although convection decreased in the next few hours, on December 5 the JTWC once again noted flaring deep convection, and late on December 6 a Tropical Cyclone Formation Alert
was issued. On the morning of December 7, both the JTWC and Japan Meteorological Agency
-RSMC Tokyo reported that a tropical depression had formed. Soon after, the depression entered the area of responsibility of PAGASA
, who named it Seniang. The depression strengthened throughout the day, and the JMA upgraded it to Tropical Storm Utor later that day. The name Utor was submitted by the United States on behalf of the Marshall Islands
, and is a Marshallese
word for squall line
.Signal no.3 has been raised in the provinces of Cebu
,Leyte,Samar Provinces
On December 8, the JMA upgraded Utor to a severe tropical storm. It intensified further and was upgraded to a typhoon by the JMA on the morning of December 9, with PAGASA
and JTWC doing the same. The storm made landfall shortly after noon local time the same day. After crossing the Philippines
, Utor took a track similar to Typhoon Chebi in November, first moving northwest then threatening to take aim at Hong Kong. It restrengthened to an 85-kt typhoon, before it slowed as it tracked in a weak steering environment within a weakness in the subtropical ridge
. It then weakened as wind shear increased and dry air entrainment occurred. The JMA downgraded it to a severe tropical storm on December 13, and to a tropical storm the same day. The next day the JTWC downgraded the storm to a tropical storm and issued its last advisory.
The 2006 ASEAN
and East Asia Summit
, originally scheduled to start December 10, was put back a month due to the storm. Typhoon Utor killed at least 78 people and left 49 others missing in the Philippines. Damages from the typhoon were estimated at $1.9 million (2006 USD).
Typhoon Utor was blamed for heavy rains of up to 350 mm within 24 hours in southern Peninsular Malaysia
, specifically Johor
, Negeri Sembilan
, Melaka and Pahang
, causing massive floods within the southern region on December 18, 2006, which was considered as the worst in the Malaysian southern region history. However, there were also reports a few days earlier that adverse weather was not to be blamed on the typhoon. The worst-affected areas were Segamat
and Kota Tinggi
, where both towns were totally inaccessible by land after all main roads leading to those towns were all flooded. Until December 24, 2006, the floods had claimed 8 lives.
started issuing public bulletins on a tropical depression southwest of Guam
. The Joint Typhoon Warning Center
initiated warnings on Tropical Depression 26W the next day, despite having not issued a Tropical Cyclone Formation Alert
. The system was upgraded to a tropical storm by the JMA and named Trami, which is a kind of rose
tree. This name was submitted by Vietnam
. The storm moved west-northwest rapidly towards the Philippines
, but struggled against wind shear and an approaching cold front. Entering the PAGASA Area of Responsibility on December 18 as it maintained minimal tropical storm intensity, it was named Tomas. The JTWC issued its final warning later that day, having never upgraded the storm to tropical storm strength, citing no indication of a significant low-level circulation centre. On December 19, the JMA downgraded the storm to a tropical depression and issued its last public bulletin as the storm dissipated over water.
in the southern Philippines. As it traveled in an erratic northwestward direction, it slowly became better organized. On January 23, the JMA assessed the storm to have attained winds of 55 km/h (35 mph 10-minute winds). Around the same time, PAGASA began issuing advisories on the system and gave it the local name Agaton. The depression weakened as it crossed over northern Samar Island
and southern Luzon
. Traveling towards the west, the system failed to strengthen and dissipated on January 27 while located over the South China Sea
, about halfway between Vietnam
and Borneo
.

followed later that afternoon. The depression necessitated Tropical Cyclone Signal No.1 in Hong Kong and Macau
, which means that the centre of a tropical cyclone is within 800 km (497.1 mi) of the respective Special Administrative Regions, and may later affect them. The depression made landfall at Guangdong at 5:55 a.m. CST on August 25 and dissipated later that morning.
The JTWC designated the system as a Tropical Depression at 9 p.m. UTC August 24, but only issued two warnings on the system.
identified a tropical depression about 360 kilometres east-northeast of Xisha on September 12 and issued Standby Signal No.1
accordingly. The tropical depression also necessitated the issuance of the Standby Signal No. 1 in Macau at 2 p.m. UTC on the same day. The JTWC designated it as a tropical depression, 15W, at 9 p.m. UTC September 12. The JMA had earlier already identified it as a tropical depression. As it strengthened and edged closer to the coastal areas of Guangdong
, the Strong Wind Signal No. 3 was issued both in Hong Kong and Macau on September 13. It made landfall in western Guangdong
around 11:30 p.m. CST that night and dissipated inland.
on September 22. The system was organized enough to be classified as Tropical Depression 17W by the JTWC the next day. The JTWC briefly upgraded it to a tropical storm on September 24. It weakened under heavy vertical wind shear and the JTWC issued its final advisory on Tropical Depression 17W before landfall in Vietnam
. The storm passed just south of Hainan and brought heavy rain to the area. The maximum rainfall recorded was 143 mm. CMA kept it as a tropical storm until it made landfall in Vietnam in the morning of September 25. In the six years since current naming conventions were introduced, this was the 13th time the JTWC recognised a tropical storm not named by the JMA. This was also the 3rd time that CMA recognised a tropical storm not named by the JMA, after one storm in the 2000 Pacific typhoon season, zero in 2001, 2002 and 2003, one in 2004.
In the post-season analysis supplied by the JTWC, it was determined that 17W never reached tropical storm intensity, thus it was downgraded to a tropical depression.
was designated Tropical Depression Ompong by PAGASA. The depression slowly moved westward toward the Philippines
, but wind shear from Typhoon Soulik prevented any intensification. The depression degenerated into an area of low pressure early the next day.
. Names are selected from the following sequential list, 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 names on the list are identical to that used in the 2005 season with the exception of Pongsona, Maemi, Sudal, Rananim, Yanyan and Tingting which were replaced by Noul, Mujigae, Mirinae, Fanapi, Dolphin and Lionrock respectively. The first storm of the season was named Chanchu, and the last storm was named Trami.
One storm, Hurricane Ioke
, entered the Western North Pacific from the Central North Pacific, retaining its name assigned by the Central Pacific Hurricane Center
. It was given the international typhoon number 0612 by the JMA.
(PAGASA) uses its own naming scheme for tropical cyclones within its area of responsibility. Lists are recycled every four years. On the 2006 list, the name "Gloria" was replaced by "Glenda". .
in December 2006, it was decided that five names - Chanchu
, Bilis, Saomai
, Xangsane
and Durian
would be retired, with replacement names due to be submitted at the 40th annual meeting of the committee. The names Sanba, Maliksi, Son Tinh, Leepi and Mangkhut were chosen respectively. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) announced that the names Milenyo and Reming would be retired due to extensive damage and loss of life. The names Mario and Ruby were chosen to replaced Milenyo and Reming respectively.

Storms
In storm information below, windspeed advisories differ from the Joint Typhoon Warning Center to the Japan Meteorological Agency as the JTWC uses the U.S. criteria of 1-minute mean to designate maximum sustained winds, while the JMA uses the 10-minute mean wind criteria to designate tropical cyclone maximum sustained winds. This difference generally means that JTWC maximum winds will appear to be higher than the maximum winds described by the JMA for the same cyclone.Typhoon Chanchu (Caloy)

, which means that the centre of a tropical cyclone is within 800 km (497.1 mi) of the respective Special Administrative Regions, and may later affect them. The depression made landfall at Guangdong at 5:55 a.m. CST on August 25 and dissipated later that morning.
The JTWC designated the system as a Tropical Depression at 9 p.m. UTC August 24, but only issued two warnings on the system.

on September 22. The system was organized enough to be classified as Tropical Depression 17W by the JTWC the next day. The JTWC briefly upgraded it to a tropical storm on September 24. It weakened under heavy vertical wind shear and the JTWC issued its final advisory on Tropical Depression 17W before landfall in Vietnam

. The storm passed just south of Hainan and brought heavy rain to the area. The maximum rainfall recorded was 143 mm. CMA kept it as a tropical storm until it made landfall in Vietnam in the morning of September 25. In the six years since current naming conventions were introduced, this was the 13th time the JTWC recognised a tropical storm not named by the JMA. This was also the 3rd time that CMA recognised a tropical storm not named by the JMA, after one storm in the 2000 Pacific typhoon season, zero in 2001, 2002 and 2003, one in 2004.
In the post-season analysis supplied by the JTWC, it was determined that 17W never reached tropical storm intensity, thus it was downgraded to a tropical depression.
