Torrential rains from Thursday to Sunday may leave more than a dozen rivers in southern China swollen above their flood warning levels, according to the Ministry of Water Resources.

Moderate to heavy rains are expected to fall in some parts of South and Southwest China during the period, as well as some areas in the region south of the lower reaches of the Yangtze River, the ministry said in a news release on Thursday.

The ministry has asked flood control authorities in these areas to roll out precautionary measures, the release said. In particular, they have been asked to take action to cope with floods in medium and small-sized rivers and mountain torrents

The rainfall may result in deluges in at least five natural water body systems, including the Yangtze and Pearl rivers and the Dongting and Poyang lakes.
