BEIJING - China's Ministry of Water Resources warned on Sunday that some small and medium-sized rivers in the country's southern regions could see floods exceeding alert levels due to heavy downpours over the next few days.

Some rivers in Zhejiang, Fujian, Guangdong, Hainan and Jiangxi, among other regions, could swell due to heavy rainfalls from Sunday to Wednesday, according to the ministry.

The ministry is making arrangements to prevent rainstorms and floods, calling for local water resource authorities to strengthen monitoring, forecasting and early warning.
