Flood - Flash

What is Flash Flooding?

As the name indicates, flash floods can develop quickly, sometimes in just a few minutes and without any visible signs of rain. Flash floods often have a dangerous wall of roaring water that carries rocks, mud, and other debris and can sweep away most things in their paths.

Flash floods are the number one weather-related killer in the U.S. because they can roll boulders, tear out trees, and destroy buildings and bridges quickly. A flash flood is a sudden, rapid flooding of low-lying areas typically caused by intense rainfall. Flash floods can also occur from the collapse of a man-made structure or ice dam. Rapidly rising water can reach heights of 30 feet or more.

How Can It Affect YOU?

Flash flooding is particularly dangerous because people attempt to drive through rushing water or down a flooded road.

Six inches of water will reach the bottom of most passenger cars, causing loss of control and possible stalling. It only takes two feet of water to lift a car or SUV and once a vehicle becomes buoyant, the water can easily push it sideways or roll it over, trapping those inside and washing them downstream. Drivers should remember this simple saying: "Turn Around - Don't Drown," and practice safe driving during flood events.

Flash flooding causes more than $2 billion in property damage each year in the U.S.
