Texas:
Four people suffered minor injuries as tornadoes spun through parts of North Texas, overturning vehicles and damaging a school complex.
A school district advisory says classes were cancelled on Monday in Rice, a town of about 950 located 45 miles (72 kilometres) south of Dallas.
Navarro County Chief Deputy Mike Cox said Rice Elementary School and five homes were damaged during a tornado late on Sunday afternoon.
Cox said a truck travelling on Interstate 45 overturned, striking a car, leaving four people with non-life threatening injuries.
Cox also says some freight train cars were derailed.
A local resident filmed a home video of the tornado crossing a highway in front of the truck he was driving.
Eric Meyers described the twister as the most powerful thing he had ever seen in his life.
"I never want to see it again," he said.
