A total of about 12,700 people were evacuated in northeast China's Liaoning Province by Monday morning due to heavy torrential rain in the region since Sunday morning, local authorities said.

Heavy to torrential rains lashed southeastern Liaoning from 8 a.m. Sunday to 11 a.m. Monday, with downpours in some areas, while the northern and western parts of the province saw light to moderate rain and localized heavy to torrential rain in a few spots.

Red alerts for torrential rain remain in effect across multiple parts of Liaoning. As of 6 a.m. on Monday, nine cities had activated flood emergency responses, according to the provincial flood control and drought relief headquarters.

The provincial emergency management department has directed eight cities, including Dalian, Anshan and Dandong, to place 3,611 rescue and emergency response teams totaling over 127,000 personnel on standby for flood relief. Dandong alone had evacuated 8,078 people by 6 a.m. on Monday.

The Dandong meteorological observatory issued a red alert for torrential rain at 11:33 a.m. on Monday, reporting that 160 to 240 millimeters of precipitation had fallen in the urban area over the previous 11 hours.

Another 100 to 130 mm is expected in the next six to eight hours, with maximum hourly rainfall intensity reaching 70 mm and the cumulative total potentially exceeding 350 mm by the end of the event.
