Meanwhile, in Changshun county, more than 3,000 residents from about 1,000 households in villages downstream of the Bancong reservoir were safely relocated after a power outage affected reservoir operations and led to overflow.

At 6 pm on Sunday, China's Ministry of Water Resources and the China Meteorological Administration jointly issued a top-level red alert for mountain torrents, warning of a high risk of flash floods in parts of southeastern Guizhou from 8 pm Sunday to 8 pm Monday.

In response, local authorities in Qiandongnan Miao and Dong autonomous prefecture strengthened monitoring of 27 rivers and mobilized thousands of officials and flood-control personnel.
