Southern China is experiencing its strongest rainfall event this year, from Tuesday to Thursday, according to the National Meteorological Center.

The center extended a yellow alert, the second in the four-tier weather warning system, for heavy rain on Wednesday. It has forecast torrential downpours across the southern regions.

From 8 am Wednesday to 8 am Thursday, parts of Jiangxi, Fujian, Guangdong provinces, Guangxi Zhuang autonomous region and Taiwan could see rainfall between 100 and 200 millimeters.

The affected areas are also forecast to experience short-term heavy precipitation, with maximum hourly rainfall of 30-50 mm and possible thunderstorms.

Rainfall in southern China is expected to weaken on Thursday. Central and eastern Xizang autonomous region and western Yunnan province will experience moderate to heavy rain, with localized torrential rain also anticipated, the center said.

Precipitation will be frequent in Yunnan and southeastern Xizang over the next five days.

Xu Jun, a chief forecaster at the center, said since southern China has already endured multiple rounds of strong rainfall since May, the latest downpour could raise risks of flooding and secondary disasters.

In contrast to the deluge in the South, North China can expect ample sunshine. Forecasts indicate that over the next 10 days, regions including North China will see rising temperatures.
