What to do

Stay off flooded roads. Turn around, don't drown. Most flood deaths occur in vehicles, and the National Weather Service says just 6 inches of moving water can knock you down.

Move to higher ground if water is rising around you. Never drive around barricades or into flooded roads. Just 1 foot of moving water can sweep a vehicle away.

Avoid underpasses, streets and low-lying areas with poor drainage. The warning lists these as places where flash flooding can occur. Keep checking National Weather Service updates until the warning ends at 9:00 PM CDT.
