A powerful storm system brought tornadoes, rainfall and hail to the central United States on Monday evening, in what is forecast to be a multi-day severe weather event.
Damage to houses, trees and power lines has been reported from Texas to Kentucky with duststorms causing cars to pile up on highways and hail the size of golfballs lashing several regions.
The powerful storms will continue on Tuesday and could extend into Wednesday, forecasters say.
After lashing parts of Texas, Illinois and Oklahoma, the weather system will extend from the northern parts of Indiana and Ohio and western Pennsylvania and move southward.
The risk for tornadoes extends from southeast Indiana across Ohio and over portions of Kentucky, West Virginia and Pennsylvania, the Storm Prediction Centre forecasts.
More than 50 million Americans from Dallas to Cincinnati were under warnings for severe weather on Monday.
Tornado warnings had been in effect for parts of Missouri, Oklahoma and Texas, which expired on Monday night.
