Heavy rain has begun in regions that are facing a multiday life-threatening flash flood event, largely in the South and Midwest. Several rounds of heavy rain from a stalled frontal system could cause extremely hazardous flooding for cities like Little Rock, Memphis, St. Louis, Louisville, Indianapolis and Cincinnati. Be prepared for flood conditions and have reliable ways to receive alerts in case of emergency. If you live in a flood-prone area or near a creek or river, monitor the situation in case water levels rise. Stay off of roads and never drive into flood waters.
