Up to 10 tornadoes have ripped across the southern United States.
Witnesses say one monster twister in Clarksdale, Mississippi stayed on the ground for 10 minutes, barrelling across farmland.
It flipped a truck and damaged homes.
It's been reported at least two people are missing in the storms so far and at least six have been killed across the states, including a seven-year-old boy who died when the car he was riding in was picked up and thrown by the storm.
A storm warning is in place in 10 southern states with more twisters forecast for Christmas Day.
