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.
The quantitative precipitation forecast is the expected amount of melted precipitation accumulated over a specified time period over a specified area. A QPF will be created when precipitation amounts reaching a minimum threshold are expected during the forecast's valid period. Valid periods of precipitation forecasts are normally synoptic hours such as 0000,0600,1200 and 1800 GMT. Terrain is considered in QPFs by use of topography or based upon climatological precipitation patterns from observations with fine detail. Starting in the mid-to-late 1990s,QPFs were used within hydrologic forecast models to simulate impact to rivers throughout the United States. Forecast models show significant sensitivity to humidity levels within the planetary boundary layer,or in the lowest levels of the atmosphere,which decreases with height. QPF can be generated on a quantitative,forecasting amounts,or a qualitative,forecasting the probability of a specific amount,basis. Radar imagery forecasting techniques show higher skill than model forecasts within 6 to 7 hours of the time of the radar image. The forecasts can be verified through use of rain gauge measurements,weather radar estimates,or a combination of both. Various skill scores can be determined to measure the value of the rainfall forecast.
The 2008 South China floods began on 26 May 2008. Four rounds of torrential rains with landslides and flooding lasted for 20 days and affected fifteen provinces in Eastern and Southern China.
Typhoon Fengshen,known in the Philippines as Typhoon Frank,was the sixth named storm and the fourth typhoon recognised by the Japan Meteorological Agency.

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,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.
Li's field is a tongue-in-cheek 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 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 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.

A series of major landslides occurred in Hong Kong in June 1972. Several apartment complexes and houses were wiped out,and at least 156 people lost their lives. The landslides had been caused by waterlogged soils in the area,a result of Typhoon Rose bringing unusually heavy rainfall in August 1971 as well as heavy rainstorms hitting Hong Kong on the days preceding the landslides.
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.
The June 2008 Hong Kong Rainstorm was a rainstorm in Hong Kong on 7 June 2008 that caused flooding and landslides. It resulted in 2 deaths and 16 injuries. The Hong Kong Observatory recorded 145.5mm of precipitation at its headquarters between 08:00 to 09:00,setting the highest one-hour precipitation record. A total of 307.1mm of precipitation was recorded during that day.
Typhoon Sarika,known in the Philippines as Typhoon Karen,was a powerful tropical cyclone which affected the Philippines,South China,and Vietnam in mid-October 2016. The twenty-first named storm and the tenth typhoon of the annual Pacific typhoon season,Sarika developed from a tropical disturbance east of the Philippines on October 13. The system steadily strengthened as it traveled westwards,becoming a tropical storm later that day and then a typhoon on October 15. Rapid intensification commenced as Sarika turned to the west-northwest towards Luzon,reaching its peak intensity just before making landfall in Aurora early on October 16. Sarika weakened significantly as it crossed land,emerging over the South China Sea as a minimal typhoon,then weakening further to a severe tropical storm on October 17. Sarika maintained its strength for the rest of the day and made landfall in Hainan province in China on October 18. Turning to the northwest,Sarika weakened quickly as it emerged into the Gulf of Tonkin,before moving onshore once again in Guangxi province on October 19. The system dissipated shortly after.
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.
Tropical Storm Pakhar,known in the Philippines as Tropical Storm Jolina,was a strong tropical storm that impacted South China during late August 2017. This storm followed Typhoon Hato which affected the area a few days prior. Pakhar was the fourteenth named storm of the Pacific typhoon season. Pakhar developed from a tropical depression to the east of Luzon during August 24,and intensified into a tropical storm later that day. Pakhar made landfall over in Aurora on August 25. Pakhar gradually intensified and peaked as a severe tropical storm by August 27,making landfall over Taishan,Jiangmen in Southern China.
Tropical Storm Ewiniar was a tropical cyclone in early June 2018 that brought prolonged heavy rains to Vietnam and South China,causing damaging floods and landslides. The fourth named storm of the 2018 Pacific typhoon season,Ewiniar developed as a tropical depression just east of Vietnam on June 2. The system moved generally northwards over the South China Sea,before intensifying into a tropical storm near the Qiongzhou Strait on June 5. Ewiniar proceeded to stall over the region as steering currents collapsed,making landfall over the Leizhou Peninsula and later over northern Hainan. Ewiniar accelerated to the northeast on June 7 and moved back over open sea,allowing it to strengthen slightly and reach peak intensity with maximum sustained winds of 75 km/h (45 mph) and a central pressure of 998 hPa. The storm made landfall in eastern Guangdong shortly thereafter and weakened into a tropical depression on June 8. The system ultimately dissipated east of Taiwan on June 11.
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.
