What to do
Do not drive on flooded roads. Turn around and find another route. Most flood deaths occur in vehicles.
Stay away from creeks, streams, washes and underpasses named in the warning. The National Weather Service says just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Move to higher ground if water is rising near you. Never drive around barricades. Stay aware of your surroundings until the warning ends at 1:45 PM MST.
