Flash flooding can occur after a hurricane has passed. Avoid driving on coastal and low-lying roads. Storm surge and hurricane-caused flooding are erratic and may occur with little or no warning. Do not try to stay with your car under these conditions. Never attempt to drive through water on a road.
Water can be deeper than it appears, and water levels can rise very quickly.
Most cars will float dangerously for at least a short while. A car can be buoyed by floodwaters and then swept downstream during a flood. Wade through floodwaters only if the water is not flowing rapidly and only in water no higher than the knees. If a car stalls in floodwater, get out quickly and move to higher ground. The floodwaters may still be rising and the car could be swept away at any moment.
