China's national meteorological authority says the middle and lower reaches of the Yangtze River will experience less heavy rain. Central and eastern provinces of Hubei, Hunan and Jiangxi will see a decline in rainfall.

But the Sichuan Basin in the southwest will see more downpours. Three continuous days of rainfall is expected, with total precipitation of 100 to 300 millimeters.

Neighboring Yunnan province will also see rainstorms today. Experts warn that as rainfall moves to upper reaches of the Yangtze River, flood control will become more challenging.
