What to do

Do not drive on flooded roads. The National Weather Service says most flood deaths occur in vehicles. If you meet water on the road, turn around and find another way.

Highway 151 from Arboles to the intersection with Highway 160 near Chimney Rock is prone to rockslides and mudslides in heavy rain. Watch for rocks and debris, and use an alternate route if you can.

Stay away from creeks, streams, underpasses and low-lying roads. Move to higher ground if water starts to rise, and 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.

Context
