What to do
Stay off flooded roads. Turn around, don't drown. Most flood deaths occur in vehicles, and at least one road in Marysville has been closed by water that makes it impassable.
Move to higher ground if water is rising near you. Never drive around barricades or into flooded roads. Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Stay alert through the warning. The National Weather Service says 1 to 2 more inches of rain are possible in the warned area, and the warning runs until 2:45 AM CDT.
