The 2006 Pacific typhoon season has no official bounds; it runs year-round in 2006, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.[1] 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. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This will result in the same storm having two names.

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)

 
DurationUnknown – Unknown
Peak intensityWinds not specified;
Main article: Typhoon Chanchu (2006)

An area of disturbed weather formed around May 5 and moved westward. 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[2] and $1.9 million in damage, much of it to agriculture.[3] 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 Vietnamese 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.[4] Chanchu is also the most intense typhoon on Hong Kong Observatory's record to enter the South China Sea in May. 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 Chinese yuan. Chanchu became extratropical later that day.

Tropical Storm Jelawat (Domeng)

 
DurationUnknown – Unknown
Peak intensityWinds not specified;

An area of disturbed weather that began as a part of a monsoon trough[citation needed]
formed around June 23 east of the Philippines, and moved slowly over the islands. The Joint Typhoon Warning Center 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 0740 LST June 29[5] and dissipated later that day.

The storm dropped heavy rainfall across southern China and Haikou recorded a rainfall of 309.7mm (12 inches) during the storm passage.[6] A total of 8.6 inches (220 mm) rain fell in 16 hours in Kampung Bundu, Malaysia.[7] The rainfall killed seven people and left one missing. The flooding from Jelawat ruined 20,000 hectares of farmland and destroyed 190 houses.[8]

Typhoon Ewiniar (Ester)

 
DurationUnknown – Unknown
Peak intensityWinds not specified;

On June 29, a persistent tropical disturbance was classified as a tropical depression by the JTWC while east of Palau. 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 moved west-northwestward over the next two days, bringing heavy rain and localized flooding to the Yap Islands.[9] After clearing Yap, the storm turned northwestward and began strengthening rapidly, becoming a typhoon on July 3 and reaching its peak intensity of 130 knots (150 mph, 240 km/h) on July 4. Ewiniar turned northward and paralleled the east coast of China, brushing some coastal cities (including Shanghai) with its outer rain bands and prompting evacuations.[10] Ewiniar was responsible for at least 30 deaths in China. 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 accross the country, it came to just 50km from Seoul.[11] No tropical cyclone had come that close to Seoul in recent years. The passage of the storm brought heavy rain that triggered floods and mudslides in the southern part of the country, killing at least six people.[10] Ewiniar became extratropical over the Sea of Japan the next day.

Severe Tropical Storm Bilis (Florita)

Template:HurricaneActive

A tropical disturbance northeast of Yap 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 Phillippines, means speedy or swift in motion.

Current storm information

As of 1500 UTC July 13, Severe Tropical Storm Bilis was located about 15 nautical miles (30 km) northwest of Taipei, Taiwan, moving west-northwest at 11 knots. According to the JTWC, it had sustained winds of 55 knots (105 km/h, 1-minute average). The official RSMC, the RSMC Tokyo, placed the storm near 25.5ºN 121.3ºE and moving west-northwest at 8 knots. It was packing sustained winds of 55 knots (105 km/h, 10-minute average).

Other storms

These systems were not officially named as tropical storms by the JMA, although the JMA might have monitored them as tropical depressions. They were, however, designated as tropical cyclones by the Philippines (PAGASA), China (CMA), and/or the Joint Typhoon Warning Center (JTWC).

PAGASA Tropical Depression Agaton

 
DurationUnknown – Unknown
Peak intensityWinds not specified;

On January 21, a tropical depression formed about 230 km east-northeast of Hinatuan, Surigao del Sur within the Philippine area of responsibility, and was named Agaton by PAGASA for Philippine warnings. The depression weakened into a low pressure system on January 24 after landfall.

The system entered into South China Sea and became better organized. Therefore, China declared the formation of a tropical depression on January 25 (source in Chinese) and forecast that it would become a tropical storm. However, the depression failed to develop.

JTWC Tropical Storm 01W (Basyang)

 
DurationUnknown – Unknown
Peak intensityWinds not specified;

On March 4, a tropical depression formed out of a wave close to the equator southeast of Palau. The JTWC upgraded it to Tropical Storm 01W at 3 p.m. UTC the same day. The JTWC downgraded it back to a depression on March 5 due to shear, and it never regained tropical storm strength before dissipating on March 7.

In the six years since current naming conventions were introduced, this was the 12th time the JTWC and the JMA had disagreed over the naming of a tropical storm, after one storm in the 2000 Pacific typhoon season, three storms in the 2001 Pacific typhoon season, two storms each in the 2002, 2003 and 2004 Pacific typhoon seasons and one in 2005.

CMA Tropical Depression 03

 
DurationUnknown – Unknown
Peak intensityWinds not specified;

On July 3, China Meteorological Administration identified a tropical depression about 200 km south of Sanya, Hainan.[12] The depression moved northwest and made landfall at 7:10pm in Hainan on the same day.[13] On the next morning, it entered Gulf of Tonkin and strengthened slightly. Eventually, the depression made its second landfall near Guangxi/Vietnam border around noon and rapidly weakened over land.[14]
