Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track.
The 1999 Pacific typhoon season was the last Pacific typhoon season to use English names as storm names. It also featured the lowest number of typhoons on record, with only five reaching this intensity. This was mainly due to a strong La Niña which persisted from last year. The season was also below-average in named storms, with only 20 of such spawning. This season also featured multiple landfalls in Hong Kong. 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. The first named storm, Hilda, developed on January 6, while the last named storm, Gloria, dissipated on November 16.
The 1993 Pacific typhoon season was the most active season for the Philippines, seeing a total of 32 storms forming or entering their area of responsibility. Overall, it was an average season, spawning 28 tropical storms, 15 typhoons and three super typhoons. The season had no official bounds; it ran year-round in 1993, 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 1937 Great Hong Kong Typhoon was one of the deadliest typhoons in Hong Kong history, with a death toll estimated between 11,000 and 13,000. Part of the 1937 Pacific typhoon season, the tropical cyclone originated on 24 August to the south of Guam, which proceeded generally to the west-northwest. On 1 September the storm entered the South China Sea, and early the next day, the typhoon passed just south of Hong Kong before making landfall in southern China. It weakened after moving ashore, dissipating on 3 September.
Typhoon Fengshen, known in the Philippines as Typhoon Frank, was the sixth named storm and the fourth typhoon recognized by the Japan Meteorological Agency. The Joint Typhoon Warning Center recognized Fengshen as the seventh tropical depression, the sixth tropical storm, and fifth typhoon of the 2008 Pacific typhoon season.
Severe Tropical Storm Kammuri, known in the Philippines as Tropical Storm Julian, was a weak but deadly tropical storm which impacted the Philippines, China, Vietnam, and Hong Kong in August 2008. The ninth named storm of the 2008 Pacific typhoon season, Kammuri developed as a tropical depression on August 4 north of Luzon. The next day, the depression intensified into a tropical storm, resulting in the Japan Meteorological Agency naming it Kammuri. The following day, Kammuri reached its peak intensity with sustained winds of 50 kn (93 km/h) before making landfall in Guangdong province, China. This would make Kammuri weaken into a tropical storm that evening, resulting in the JTWC issuing their last advisory on the system. Kammuri would later emerge in the Gulf of Tonkin the next day, making a second landfall over Guangxi province, China. After Kammuri made landfall, the JMA issued its final advisory on Kammuri.
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 Nuri, known in the Philippines as Typhoon Karen, was the 12th named storm and the seventh typhoon that was recognised by the Japan Meteorological Agency. The Joint Typhoon Warning Center recognised it as the 13th tropical depression, the 12th tropical storm and the 8th typhoon of the 2008 Pacific typhoon season. The name Nuri was submitted to the World Meteorological Organisation's Typhoon Committee by Malaysia in 2003 after the name Rusa was retired in 2002. The name Nuri is Malay for a blue crowned parroquet, a type of parrot. The name Karen was assigned by PAGASA to a tropical depression for the second time, the other time being in 2004 to Typhoon Rananim.
Typhoon Prapiroon, known in the Philippines as Tropical Storm Henry, was a minimal typhoon which caused deadly flooding in southern China in August 2006. Prapiroon developed out of a persistent area of convection accompanied by an area of low pressure on July 25 about 120 km (75 mi) west-southwest of Yap. Two days later, both the Japan Meteorological Agency (JMA) and PAGASA classified the system as a tropical depression, with PAGASA giving it the local name 'Henry'. By July 31, the Joint Typhoon Warning Center (JTWC) classified the system as Tropical Depression 07W. A strong subtropical ridge located to the north of the depression led to a west-northwest movement for most of the storm existence.
Typhoon Wayne, known in the Philippines as Typhoon Miding, is one of the longest-lived tropical cyclones on record in the north-western Pacific Ocean. The system meandered for 21 days in August–September 1986 between the South China Sea and far western tropical North Pacific Ocean, staying within the monsoon trough and causing heavy rains across the Philippines, Taiwan, southeast China, Hainan Island, and Vietnam. Its maximum sustained winds peaked at category two strength on the Saffir–Simpson scale. Various signals were raised for Hong Kong three times due to Wayne's unusual track. A total of 490 perished, and the storm caused US$399 million in damage.
Typhoon Angela, known in the Philippines as Typhoon Rubing, was an intense tropical cyclone that formed in late September 1989. The storm developed from a tropical disturbance in the monsoon trough and moved generally westward throughout its duration. The storm ultimately peaked in intensity as a super typhoon and struck northern Luzon in the Philippines. After weakening and traversing the South China Sea, Angela bypassed Hainan to the south and struck Vietnam before dissipating. The storm caused severe damage and 119 fatalities in the Philippines. Thousands of houses were damaged, and hundreds of thousands of residents were impacted by the typhoon. Monetary damage is placed at $8 million.
Li's field is a satirical conspiracy theory in Hong Kong over the existence of a force field that repels tropical cyclones from the city.
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 of the 2012 Pacific typhoon season, Vicente began as a tropical depression on July 18, 2012 northeast 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 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.
Typhoon Sally, known in the Philippines as Typhoon Maring, was an intense tropical cyclone that caused widespread damage across southeastern Asia, particularly in China, in September 1996. Forming well east of the Philippines on 5 September, Sally quickly intensified as it tracked westward within favorable conditions. The system reached tropical storm intensity several hours after tropical cyclogenesis was completed, and strengthened further into typhoon intensity the following day. On 7 September, Sally reached super typhoon status shortly before attaining its peak intensity with maximum sustained winds of 260 km/h (160 mph) and a barometric pressure of 940 mbar. Quickly moving across the South China Sea, Sally substantially weakened but remained a strong typhoon before making its first landfall on the Leizhou Peninsula on 9 September. The tropical cyclone's trek brought it briefly over the Gulf of Tonkin before making a final landfall near the border of China and Vietnam. The typhoon rapidly deteriorated inland and dissipated later that day.
Typhoon Usagi, known in the Philippines as Super Typhoon Odette, was a tropical cyclone which affected Taiwan, the Philippines, China, and Hong Kong in September 2013. Usagi, which refers to the constellation Lepus in Japanese, was the fourth typhoon and the nineteenth tropical storm in the basin. Developing into a tropical storm east of the Philippines late on September 16, Usagi began explosive intensification on September 19 and ultimately became a violent and large typhoon. Afterwards, the system weakened slowly, crossed the Bashi Channel on September 21, and made landfall over Guangdong, China on September 22.
Typhoon Dot was a strong tropical cyclone that made landfalls on Luzon and near Hong Kong in October 1964. It was the fifth typhoon to impact Hong Kong during the active 1964 Pacific typhoon season, and prompted the issuance of the No. 10 typhoon signal from the Royal Observatory in Hong Kong—the highest warning possible. The storm's precursor disturbance formed west of Pohnpei on October 3 and tracked towards the west, becoming a tropical storm by October 6. Gradually strengthening, Dot moved towards the west-northwest, northwest, and then curved west, leading to a landfall at typhoon intensity on Luzon on October 9. A freighter with 32 crewmembers went missing west of the island after passing through the typhoon and was never recovered.
Typhoon Hato, known in the Philippines as Severe Tropical Storm Isang, was a strong tropical cyclone that struck South China in August 2017. 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 Mangkhut, known in the Philippines as Super Typhoon Ompong, was a powerful and catastrophic Category 5 tropical cyclone that caused extensive damage in Guam, the Philippines, and South China in September 2018. It was the strongest typhoon to strike Luzon since Megi in 2010, and the strongest to make landfall anywhere in the Philippines since Meranti in 2016. Mangkhut was also the strongest typhoon to affect Hong Kong since Ellen in 1983.
Severe Tropical Storm Higos, known in the Philippines as Tropical Depression Helen, was a tropical storm that affected China and Vietnam around the same area as Nuri two months prior. Higos formed from a tropical disturbance north of Luzon, the Philippines, on August 16. The storm tracked northeast and quickly intensified, becoming a tropical storm on August 17. The storm made landfall in Zhuhai, Guangdong at peak intensity on August 19, and quickly weakened soon after. Higos killed 7 people and caused 45 billion đồng in damages in Vietnam. Higos also caused more than US$140 million in damages, but no fatalities in China.
