Tornadoes barrelled across the midwestern US and portions of the country’s south-east, knocking out electricity and damaging buildings in several states.
The storms killed at least two people.
Meteorologists said a cold front moving east collided with warm, unstable air to produce severe thunderstorms and funnel clouds across Kentucky, Indiana, Illinois and Tennessee.
In Madisonville, Kentucky, roofs of homes were caved in, walls were blown out and entire buildings were blown off foundations.
Police cruisers and fire trucks lined the streets, setting up checkpoints.
In Tennessee, Henry County’s emergency officials scrambled for shelter when their offices took a direct hit from a tornado.
Downed power lines and trees made many roads in the outlying areas of the county impassable.
Jason Puma, a meteorologist with the National Weather Service in Indianapolis, said some of the storms had winds in excess of 100 mph.
