Tropical Storms and Hurricanes Hurricanes pack a triple punch: high winds, heavy rain, and flying debris. They can cause storm surges to coastal areas, as well as create heavy rainfall which in turn causes flooding hundreds of miles inland.

When hurricanes weaken into tropical storms, they generate rainfall and flooding that can be especially damaging since the rain collects in one place.

Spring Thaw During the spring, frozen land prevents melting snow or rainfall from seeping into the ground. Each cubic foot of compacted snow contains gallons of water and once the snow melts, it can result in the overflow of streams, rivers, and lakes. Add spring storms to that and the result is often serious spring flooding.

Heavy Rains Several areas of the country are at heightened risk for flooding due to heavy rains. The Northeast is at high risk due to heavy rains produced from Nor easters. This excessive amount of rainfall can happen throughout the year, putting property at risk.

Flash Floods Flash floods are the #1 weather related killer in the U.S. since they can roll boulders, tear out trees, and destroy buildings and bridges. A flash flood is a rapid flooding of low lying areas in less than six hours, which is caused by intense rainfall from a thunderstorm or several thunderstorms. Flash floods can also occur from the collapse of a man made structure or ice dam.

New Development Construction and development can change the natural drainage and create brand new flood risks. That is because new buildings, parking lots, and roads mean less land to absorb excess precipitation from heavy rains, hurricanes, and tropical storms.
