Southeastern China, Vietnam Face Weekend Heavy Rain

Heavy rain and thunderstorms will take aim at southeastern China and northern Vietnam this weekend, heightening concerns for flash flooding.

The soaking will commence Saturday night local time around the Chinese provinces of southern Sichuan, Guizhou and Hunan.

The heavy rain will then spread eastward to the coast on Sunday, south of Shanghai, as drenching thunderstorms erupt across the provinces of Yunnan, Guangxi and Guangdong and northern Vietnam.

However, the majority of these thunderstorms will take until Sunday night to spread to Hong Kong and the Vietnamese capital of Hanoi.

The main band of rain will also reach Taiwan Sunday night but will be preceded by periods of rain earlier in the weekend.

Rain amounts will be on the order of 25 to 75 mm (1 to 3 inches) this weekend throughout southeastern China, northern Vietnam and Taiwan. Such totals could lead to flash flooding, as well as mudslides in the higher terrain.

The impending soaking to Hong Kong comes just a little more than a month after torrential thunderstorms and hail slammed the city at the end of March.

Since then, April featured more typical rainfall amounts and above-normal warmth for Hong Kong.

Near-term flooding concerns across Asia will not just be confined to the vicinity of southeastern China.

AccuWeather.com meteorologist Eric Wanenchak has put Bangladesh and northeastern India on alert for flash flooding through this weekend. A total of 75 to 125 mm (3 to 5 inches) of rain expected from rounds of drenching showers and thunderstorms.
