Tropical Depression 16W formed 205 nautical miles (375 km) east-southeast of Dong Tac Airport, Vietnam on the morning of 16 September. It reached tropical storm strength overnight local time and was named Vicente, a Chamorro male name. Shortly after forming, Vicente interacted with a tropical disturbance west of Luzon and made a cyclonic loop. Vicente then absorbed the disturbance before passing just south of Hainan Island. Eventually, Vicente tracked into the Vietnam coast northwest of Huế on 18 September and gradually dissipated. [1]



On 17 September, the Hong Kong Observatory issued a standby signal No.1 as the outer bands of Vicente brought showers and thunderstorms to Hong Kong. The signal was dropped the next day as the storm moved away from Hong Kong. Red flags were hoisted at numerous beaches due to the rough seas. [2]


Ahead of the storm, about 9,000 residents evacuated inland while others worked to protect the thousands of dykes along the shore. [3]


In anticipation of severe flooding in the capital city of Bangkok, about 2,000 water pumps and 1.7 million sandbags were deployed to prevent significant flooding and to minimize the flooding from nearby rivers. Large forklift trucks were sent to ten stations set up around the city to assist any large trucks which might run into trouble during the storm. An additional 130 smaller forklifts were provided to assist smaller vehicles. [4] A total of seven million sandbags were stockpiled for use around the country. [5]



Tropical Storm Vicente brought showers and thunderstorms to southern China but had little impact. Rough seas produced by the storm caused the drownings of two swimmers in Ham Tin Wan of Sai Kung. The lowest pressure recorded was 1010.4 hPa (mbar) on September 17. [2] The rough seas also led to a Chinese ship striking a reef. All 17 crew members were rescued. [1]


Vicente dropped heavy rains throughout Vietnam, notably peaking at 310 mm (12.2 in) in Sơn La, 198 mm (7.7 in) in Tam Đảo District, and 164 mm (6.4 in) in Hòa Bình. Upwards of 150 mm (5.9 in) fell within 30 hours in northern areas of the county. The rains led to increased water levels in the Thao River, which threatened to overflow and flood several villages. In Thanh Hóa Province, an estimated 1,600 homes collapsed and 9,700 dykes were damaged. Large expanses of rice fields were submerged in floodwaters. [3] In Hà Tĩnh Province, a total of 3,500 homes were submerged by floodwaters and an additional 450 residences were evacuated. [6] An additional 3,000 homes were damaged and 250 were destroyed in other areas throughout Vietnam. A landslide in Yên Bái Province killed three people and injured five others. Flooding destroyed a bridge in Duong Quy and inundated a newly built school. [7] A boy in Quỳnh Lưu District was killed when a tree, knocked down by the storm, fell on him. [8] A total of 40,000 hectares (98,842 acres) of farmland was lost due to the storm. Damages totaled to 55 billion (US$3.48 million). [3] In all, at least 20 people were killed by the storm. [1]


The remnants of Vicente dropped heavy rains over drought-stricken areas of Thailand. One reservoir, which has a maximum capacity of 8 million cubic metres (282.5 million cubic feet), contained only 312,000 cubic metres (11 million cubic feet) of water. Following the storm, the reservoir gained 288,000 cubic metres (10.1 million cubic feet) of water. At least seven homes were inundated with mud due to the rains in Soi Siang Tai.

2006 Pacific typhoon season

The 2006 Pacific typhoon season was a below-average season that produced a total of 23 named storms, 15 typhoons, and six super typhoons. The season ran throughout 2006, though most tropical cyclones typically develop between May and October. The season's first named storm, Chanchu, developed on May 9, while the season's last named storm, Trami, dissipated on December 20. Also, this season was more active, costly, and deadly than the previous season.

1999 Pacific typhoon season Typhoon season in the Pacific Ocean

The 1999 Pacific typhoon season was the last Pacific typhoon season to use English names as storm names. It was a very inactive season, featuring the lowest number of typhoons on record, five. It had no official bounds; it ran year-round in 1999, 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.

Tropical Storm Kammuri (2002) Pacific severe tropical storm in 2002

Severe Tropical Storm Kammuri, known in the Philippines as Tropical Storm Lagalag, killed hundreds of people in the wake of a deadly flood season in China. The system developed from a large monsoonal system that persisted toward the end of July 2002 near the Philippines. On August 2, a tropical depression formed off the northwest coast of Luzon and moved west-northwestward. Late on August 3, it intensified into Tropical Storm Kammuri off the coast of Hong Kong. A weakening ridge turned the storm northward toward the coast of China. The storm made landfall with late on August 4, after reaching peak winds of 100 km/h (65 mph). The system dissipated over the mountainous coastline of eastern China and merged with a cold front on August 7.

Typhoon Kent (1995)

Super Typhoon Kent, known in the Philippines as Typhoon Gening, was a powerful Category 4 equivalent typhoon that formed in late August during the 1995 Pacific typhoon season.

Typhoon Pabuk (2007)

Typhoon Pabuk, known in the Philippines as Tropical Storm Chedeng, was a minimal typhoon that formed on August 5, 2007. The system made landfall on Taiwan on August 7, and on August 9 Pabuk passed to the south of Hong Kong.

Typhoon Hagupit (2008) Pacific typhoon in 2008

Typhoon Hagupit, known in the Philippines as Typhoon Nina, was a powerful cyclone that caused widespread destruction along its path in September 2008. The 21st depression, 14 tropical storm and 10th typhoon of the 2008 Pacific typhoon season, Hagupit developed from a tropical wave located a couple hundred miles east of the Marshall Islands on September 14th. Moving generally north-west westwards towards the Philippines, the depression gradually intensified into a tropical storm the following day, and then into became a typhoon on September 22 off the northern coast of Luzon. Located within an environment conducive for strengthening, Hagupit rapidly strengthened to attain 10-min sustained winds of 165 km/h and 1-min sustained winds of 230 km/h. After making landfall in Guangdong province in China at peak intensity on September 23, Hagupit rapidly weakened over rugged terrain and dissipated on the 25th.

Typhoon Tingting Pacific typhoon in 2004

Typhoon Tingting was a destructive tropical cyclone that produced record-breaking rains in Guam. The eighth named storm of the 2004 Pacific typhoon season, Tingting originated from a tropical depression over the open waters of the western Pacific Ocean. The storm gradually intensified as it traveled northwest, becoming a typhoon on June 28 and reaching its peak the following day while passing through the Mariana Islands. After maintaining typhoon intensity for three days, a combination of dry air and cooler sea surface temperatures caused the storm to weaken as it traveled northward. On July 1, the storm passed by the Bonin Islands, off the coast of Japan, before moving out to sea. By July 4, Tinting had transitioned into an extratropical cyclone. The remnants were last reported by the Japan Meteorological Agency, the Regional Specialized Meteorological Center for the western Pacific basin, near the International Date Line on July 13.

Typhoon Conson (2004) Pacific typhoon in 2004

Typhoon Conson, known in the Philippines as Typhoon Frank, was the first of the record ten typhoons to impact Japan during the 2004 Pacific typhoon season. Developing out of a tropical depression near the northern Philippines in early June, Conson slowly traveled towards the north. Gradually strengthening, the storm reached typhoon status late on June 7 according to the Joint Typhoon Warning Center and several hours later according to the Japan Meteorological Agency. After turning towards the northeast, the typhoon brushed Taiwan and reached its peak intensity with winds of 150 km/h on June 9. After reaching its peak, Conson gradually weakened, passing through Okinawa before being downgraded to a tropical storm the next day. On June 11, the storm made landfall as a minimal tropical storm in the Kōchi Prefecture just before becoming extratropical. The extratropical remnants continued towards the northeast and were last mentioned on June 14 crossing the International Date Line.

Tropical Storm Soudelor (2009) Pacific tropical storm in 2009

Tropical Storm Soudelor, known in the Philippines as Tropical Depression Gorio, was a weak tropical cyclone that produced deadly flooding in the Philippines, China and Vietnam in July 2009. Forming out of an area of low pressure on July 9, Soudelor failed to maintain deep convection around its center for the duration of its existence. On July 10, the depression brushed the northern Philippines and intensified into a tropical storm on July 11. Later that day, the storm crossed the Leizhou Peninsula. The last public advisory from the JMA was issued the following day after Soudelor made landfall in southern China.

Tropical Storm Mujigae (2009)

2017 Pacific typhoon season Period of formation of tropical cyclones in the Western Pacific Ocean in 2017

The 2017 Pacific typhoon season was a below-average season in terms of accumulated cyclone energy and the number of typhoons and super typhoons, and the first since the 1977 season to not produce a Category 5-equivalent typhoon on the Saffir–Simpson scale. The season produced a total of 27 named storms, 11 typhoons, and only two super typhoons, making it an average season in terms of storm numbers. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25, while the season's last named storm, Tembin, dissipated on December 26. This season also featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.

Tropical Storm Zita

Severe Tropical Storm Zita, known in the Philippines as Tropical Storm Luming, was a short-lived tropical cyclone that killed seven people throughout southern China in August 1997. Originating from a tropical disturbance over the South China Sea on August 19, Zita tracked westward as it quickly strengthened within a region of light wind shear, attaining winds of 140 km/h (85 mph) as it made landfall along the Leizhou Peninsula early on August 22. Maintaining this intensity, the storm made a second landfall in northern Vietnam later that day before rapidly weakening over land. The remnants of Zita were last noted over extreme northwestern Vietnam on August 24.

Typhoon Brian (1989) Pacific typhoon in 1989

Typhoon Brian was the first in a series of tropical cyclones to impact southern China and northern Vietnam in October 1989. Originating from an area of low pressure associated with a monsoon trough in late-September, Brian quickly organized into a tropical storm over the South China Sea on September 30. Tracking along a general west-southwest to westerly course, the storm attained typhoon status on October 1 before making landfall along the southern coast of Hainan Island the following day. Slight weakening occurred during Brian's brief passage of Hainan Island before the system entered the Gulf of Tonkin. The storm ultimately struck Vietnam on October 3 before dissipating the next day over Laos.

Typhoon Vicente

Typhoon Vicente, known in the Philippines as Tropical Depression Ferdie, was the strongest tropical cyclone to strike the Chinese province of Guangdong since Hagupit in 2008, and was regarded as the strongest storm to affect Hong Kong and Macau in more than ten years. The eighth named storm and third typhoon in the 2012 Pacific typhoon season, Vicente began life as a tropical depression on July 18, 2012 north east of the Philippines. Vicente soon steadily moved into the South China Sea, and began to intensify above warm sea waters, and began explosive intensification early on July 23, and started to charge toward the Guangdong region prompting the Hong Kong Observatory (HKO) to issue the Hurricane Signal, No. 10, the first since York in 1999. The Macao Meteorological and Geophysical Bureau also hoisted the Signal No. 9 for the first time since York and after the transfer of sovereignty over Macau. Late on the same day, Vicente made landfall over Taishan in Guangdong, China.

Tropical Storm Vongfong (2002) Pacific tropical storm in 2002

Tropical Storm Vongfong affected China after a deadly flood season. The 14th named storm of the 2002 Pacific typhoon season, Vongfong developed as a tropical depression on August 10. Initially it was disorganized due to hostile conditions, and it failed to intensify significantly before crossing the Philippine island of Luzon. There, flooding forced 3,500 people to evacuate their homes. In the Philippines, the storm killed 35 people and caused $3.3 million in damage.

Tropical Storm Toraji (2007) Pacific tropical storm in 2007

Tropical Storm Toraji was a short-lived and minimal tropical cyclone that brought inundating rainfall to areas of Southeast Asia in July 2007. The name Toraji was contributed to the western Pacific typhoon naming list by North Korea and stands for a broad bell flower. The third named storm of the annual typhoon season, Toraji developed from an area of disturbed weather within the South China Sea on July 4. As a result of its northwesterly track, the tropical depression moved over Hainan shortly after tropical cyclogenesis. Upon its emergence into the Gulf of Tonkin on July 5, Toraji quickly intensified into a tropical storm with winds of 65 km/h (40 mph); this would be the tropical cyclone's peak intensity for its entire duration. However, the JMA indicated that tropical storm intensity had been reached a day earlier. On the evening of July 5, Toraji made its final landfall on Dongxing, Guangxi before rapidly deteriorating inland and degenerating into a remnant low-pressure area by the following day.

Tropical Storm Koni Pacific tropical storm in 2003

Severe Tropical Storm Koni, known in the Philippines as Tropical Storm Gilas, caused moderate damage to areas of China and Vietnam in July 2003. The eighth tropical storm in the western Pacific that year, Koni originated from a disturbance situated within the monsoon trough well east of the Philippines on July 15. Tracking westward, intensification was slow and the system remained a tropical depression as it moved across the central Philippines on July 17. Upon moving into the South China Sea, however, conditions allowed for quicker strengthening, and as such the cyclone reached tropical storm status on July 18 before reaching its peak intensity with maximum sustained winds of 110 km/h (70 mph) and a minimum barometric pressure of 975 mbar, making it a severe tropical storm. However, atmospheric conditions began to deteriorate as Koni made landfall on Hainan on July 21, weakening the system. The tropical storm continued to weaken as it moved over the Gulf of Tonkin prior to a final landfall near Hanoi, Vietnam the following day. Tracking inland, the combination of land interaction and wind shear caused Koni to dissipate over Laos on July 23.

Typhoon Krovanh (2003) Category 2 Pacific typhoon in 2003

Typhoon Krovanh, known in the Philippines as Typhoon Niña, was a moderate tropical cyclone that caused a swath of damage stretching from the Philippines to Vietnam in August 2003. The fifteenth named storm and sixth typhoon in the western Pacific that year, Krovanh originated from a tropical disturbance within the monsoon trough on August 13. Despite rather favorable conditions, the initial tropical depression did not intensify significantly and degenerated into a remnant low on August 18. However, these remnants were able to reorganize and the system was reclassified as a tropical cyclone a day later. Intensification was rather rapid upon the storm's reformation – the depression reached tropical storm status on August 20 and then typhoon intensity two days later. Shortly after, Krovanh made landfall on Luzon at peak intensity with winds of 120 km/h (75 mph). The typhoon emerged into the South China Sea as a much weaker tropical storm, though it was able to restrengthen over warm waters. Once again at typhoon intensity, Krovanh clipped Haiyan before moving over the Leizhou Peninsula on its way to a final landfall near Cẩm Phả, Vietnam on August 25. Quick weakening due to land interaction occurred as Krovanh moved across northern Vietnam, where the storm met its demise the following day.

Typhoon Hato Category 3 typhoon in August 2017

Typhoon Hato, known in the Philippines as Severe Tropical Storm Isang, was a strong tropical cyclone that struck South China in August 2017. Developing as the thirteenth named storm and the fourth typhoon of the Pacific typhoon season, Hato formed as a tropical depression over the east of Luzon on 19 August. The system further developed and became a tropical storm the next day. On 21 August, Hato emerged over the northern portion of the South China Sea and reached typhoon intensity. Rapid intensification ensued on 23 August, and Hato became a Category 3-equivalent typhoon before making landfall over Jinwan, Zhuhai. The storm further weakened over land and dissipated on 24 August.

Typhoon Maggie Pacific typhoon in 1999

Typhoon Maggie, known in the Philippines as Typhoon Etang, was a large and powerful typhoon that affected the Philippines and southeast Asia. The sixth tropical cyclone and second typhoon of the 1999 Pacific typhoon season, Maggie developed from a monsoon trough over the Philippine Sea on June 1. Quickly intensifying to tropical storm strength the following day, Maggie followed a northward course as it continued to intensify, reaching typhoon strength at 18:00 UTC as it turned northwestward. Maggie rapidly intensified to reach its peak intensity as a Category 3 equivalent typhoon on June 5 as it passed through the Luzon Strait. The typhoon brushed Taiwan on June 6 and began to weaken, making landfall near Hong Kong as a minimal typhoon on June 7. Afterward, Maggie weakened to a tropical storm as it briefly moved offshore. The storm moved back onshore the following day and quickly weakened, degenerating into a remnant area of low pressure on June 8.
