What to do
Do not drive on flooded roads. Low water crossings become dangerous in heavy rain, and the National Weather Service says not to attempt to cross flooded roads. Find an alternate route.
If you are near a creek, wash or low-lying area, move to higher ground. Never drive around barricades. Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Expect some dirt roads to turn muddy and impassable. Paved roads and underpasses could flood too. If you are in a campground or recreation area named in the warning, stay aware of your surroundings and be ready to leave low ground.
