What to do
Do not drive into flooded roads. The National Weather Service says most flood deaths occur in vehicles. Turn around and find another route, and never drive around barricades.
Use extra caution at night, when flood dangers are harder to see. Underpasses, small creeks and low-lying areas can flood quickly.
If water is rising where you are, move to higher ground. National Weather Service guidance notes that just 6 inches of moving water can knock you down, and 1 foot can sweep a vehicle away.
The warning lists Washington, Clifton, Linn, Greenleaf, Barnes, Palmer and Vining. Stay alert to updates until the warning ends at 5:00 AM CDT.
