What to do
Do not drive on flooded roads. The National Weather Service says to turn around, don't drown, because most flood deaths occur in vehicles.
Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away. Never drive around barricades.
If you are near rivers, creeks, streams or other low-lying areas, move to higher ground. Stay aware of your surroundings and check for updates until the warning ends at 11:45 AM MDT Tuesday.
