At least 22 people have died from flash flooding and Tornado damage that swept across multiple states in the the Midwestern and southern parts of the US over the weekend, officials have said.
Nearly half of the reported deaths, which included children and elderly people, were in Tennessee, and three were in Missouri.
Three people died in Kentucky while Indiana, Mississippi, Georgia and Arkansas have also reported deaths from the storm.
The fierce weather has caused rivers to swell and the National Weather Service warned that dozens of locations would reach "major flood stage" even as the rain slows down.
As many as nine million Americans were under a flood watch on Monday, US media reported.
