Typhoon Rammasun

There is a major typhoon (hurricane) in the Western Pacific, Rammusan, which has already caused flooding and damage in the Phillipenes, where it killed 12 people, heading for southern China, and expected to affect northern Vietnam later on. From Accuweather:

Warm ocean waters combined with light wind shear will allow the storm to remain well organized through Friday as it approaches Hainan Island. Rammasun will likely bring widespread winds of 100 mph to northern Hainan Island on Friday afternoon and Friday night with higher gusts. Widespread wind damage is expected across northern Hainan, as well as the Leizhou Peninsula to the north.

UPDATE Friday AM: The typhoon is battering the coast in Hainan and Guangdong provinces in southern China China, and the Chinese have classified this as a "red alert" typhoon, the highest category for them.
