Parts of the Midwest and South faced the possibility of torrential rains and life-threatening flash floods Friday, while many communities were still reeling from tornadoes that destroyed whole neighborhoods and killed at least seven people.
Forecasters warned of catastrophic weather on the way, with round after round of heavy rains expected in the central U.S. through Saturday. Satellite imagery showed thunderstorms lined up like freight trains to take the same tracks over communities in Arkansas, Tennessee and Kentucky, according to the national Weather Prediction Center in Maryland.
