At least 43 people are now known to have died during Christmas storms in the US.
Flash floods hit Missouri and Illinois, there've been blizzards in New Mexico, and tornadoes have struck Texas, where 11 people were killed in the Dallas area.
One twister over the weekend recorded winds of up to 200 miles per hour.
The Governors of Missouri and New Mexico have declared a state of emergency.
Nearly 1,500 flights were cancelled due to the weather, about half of which were in Dallas.
