In the Western Pacific basin, where the typhoon season can last until December at lower latitudes, large tropical cyclones such as Super Typhoon Yagi and Tropical Storm Trami have killed more than 1,000 people in East Asia this year.
Typhoons are more widely known as a damaging summer weather phenomenon, but autumn typhoons can be super strong, take unusual routes, and join cold air to create more extreme wind and rainstorms, China Meteorological Administration’s public weather service chief Zhu Dingzhen told state broadcaster CCTV.
Peripheral circulation from Kong-rey and cold air from China’s north will combine, bringing about up to 180mm of rain from Thursday evening into Friday, said local media.
Local media warned of extreme rainfall, with hourly precipitation possibly reaching 70mm.
Aside from Shanghai, China’s national forecaster has also issued rainstorm warnings for parts of China’s southeast and eastern provinces, including for Fujian, Zhejiang and Jiangsu.
Zhejiang issued a typhoon warning and also suspended some trains, while Fujian has raised its emergency response levels for floods and storms.
