What typhoon struck China in 2012 approached within 800 km of Hong Kong and posed a threat of deteriorating conditions in Hong Kong?
Typhoon Vicente Typhoon Vicente, known in the Philippines as Tropical Depression Ferdie, was regarded as the most powerful storm to strike southern China in recent years, as it made landfall as a powerful category 4 equivalent-typhoon. Vicente was also a powerful tropical cyclone that struck Macau and nearly impacted Hong Kong, as well as Guangdong and Guangxi provinces in China. Vicente, the eighth named storm and third typhoon in the 2012 Pacific typhoon season, 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.
Typhoon Janis (1992) Typhoon Janis, known in the Philippines as Typhoon Gloring, was an early-season typhoon that struck Japan during August 1992. An area of disturbed weather formed near Pohnpei in late-July 1992, and after an increase in thunderstorm activity, and on August 3, a tropical depression developed. After tracking near Guam, Janis tracked generally westward, and on August 5, the storm was believed to have attained typhoon intensity. After intensifying at a brisk pace, Janis attained peak intensity on August 6 near Okinawa. Thereafter, the typhoon began to weaken and accelerate as it recurved towards Kyushu, where it made landfall on the next day. Land interaction took its toll on the typhoon as it tracked northeast, paralleling the western coast of Honshu. On August 9, Janis transitioned into an extratropical low over Hokkaido.
