    Parts of east and southeast China can expect heavy rain with the threat for flooding this week. Local rainfall amounts in excess of 100 mm (4 in) are expected.

    A stalled frontal boundary over southeast China led to daily rounds of rain and thunderstorms the past several days. During this stretch of time, 25-75 mm (1-3 in) of rain was common from eastern Sichuan and Guizhou into Fujian and Zhejiang provinces.

    From Friday through Sunday, another cold front will produce a period of heavy rainfall across the eastern third of China. This front will bring another 25-75 mm (1-3 in) of rain in a short period over a more widespread region, continuing the threat for flooding.

    Shanghai will experience some of the heavy rainfall from this round of rain and thunderstorms Friday night and Saturday. Generally 25-50 mm (1-2 in) is expected across the city which could produce some localized flash flooding.

    The storms will also push all the way into Hong Kong by Sunday and Sunday night; however, the heaviest rainfall is expected to remain well to the north with little or no flood threat for the city.

    The greatest concern for flooding is the corridor from Sichuan and Guizhou through Fujian and Zhejiang, including the cities of Ganzhou, Changsha and Wenzhou, where an additional 25-75 mm (1-3 in) of rain is expected through Sunday. Local rainfall amounts over 125 mm (5 in) will be possible.

    As the storm begins to depart China, a soaking rain will affect the Korean Peninsula and Japan from Sunday through Tuesday. The slow movement of this storm system could lead to some localized flooding across these areas; however, no widespread problems are expected.
