What to do
Do not drive into flooded roads. Turn around and find another route. The National Weather Service says most flood deaths occur in vehicles, and 6 inches of moving water can knock you down.
Stay away from streams, creeks and dry washes. The National Weather Service warns that they can become dangerous currents in a matter of minutes, even from distant rainfall. Campers and hikers should avoid streams and creeks.
Move to higher ground if water is rising near you. Never drive around barricades. The warning includes Interstate 15 between mile markers 43 and 47, so check road conditions before you travel.
Context
