Oklahoma is not done with the severe storm risk after heavy rainfall caused flooding on Saturday and several tornadoes hit the state early Sunday morning.

Tens of millions of people in the central U.S. from Texas to the Midwest will be on alert for severe weather through the start of the workweek as cleanup efforts continue in the Oklahoma City metro after tornadoes left widespread damage and injuries across the region.

On Wednesday afternoon, a tornado watch was issued for Oklahoma County and a large portion of northern and northwest Oklahoma.
