What to do
Do not drive into flooded roads. The National Weather Service says to turn around, don't drown, because most flood deaths occur in vehicles. Never drive around barricades.
If you are in the warned area, move to higher ground and stay away from creeks, streams, underpasses and low-lying roads. Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
The National Weather Service says 1 to 1.5 inches of additional rain is possible, so conditions may keep changing. Check for updates until the warning ends or is cancelled.
