Flood Facts...
Flash floods occur within a few minutes or hours of excessive rainfall or a dam failure. Flooding is a longer-term event and may last a week or more.
Most flash flooding is caused by (1) slow-moving thunderstorms, (2) thunder-storms repeatedly moving over the same area or (3) heavy rains from hurricanes and tropical storms.
Flash floods can roll boulders, tear out trees, and destroy buildings and bridges.
Densely populated areas have a high risk for flash floods. The construction of buildings, highways, driveways, and parking lots increases runoff by reducing the amount of rain absorbed by the ground.
Water can erode the roadbed creating unsafe driving conditions.
Many flash floods occur at night when flooded roads are hard to see.
2 feet of water will float your car, truck or SUV!!! 6 inches of fast-moving floodwater can knock you off your feet.
Nearly half of all flash flood fatalities are auto related. If your car stalls, leave it and seek higher ground, if you can do so safely.
Underpasses can fill rapidly with water, while the adjacent roadway remains clear. Driving into a flooded underpass can quickly put you in 5-6 feet of water.
Flood Safety Tips...
Never try to walk, swim, or drive through swift-moving floodwater. Remember, 2 feet of water will float your vehicle and 6 inches of fast moving floodwater can knock you off your feet.
If you come upon floodwaters, STOP, TURN AROUND AND GO ANOTHER WAY!!
Do not attempt to drive through a flooded road.
If your car stalls, leave it and seek higher ground, if you can do so safely.
Stay informed about the storm and possible flooding by listening to your NOAA weather radio, commercial radio, television or internet.
