In the United States, floods are the most common severe weather emergency. 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.

Several factors contribute to flash flooding. Most flash flooding is caused by slow-moving thunderstorms, thunderstorms repeatedly moving over the same area, or heavy rains from hurricanes and tropical storms. Flash floods occur within a few minutes or hours of excessive rainfall, a dam or levee failure, or a sudden release of water held by an ice jam. Topography, soil conditions, and ground cover also play an important role.

Rapidly rising water can reach heights of 30 feet or more. Flash flood-producing rains can also trigger catastrophic mud slides. You will not always have a warning that these deadly, sudden floods are coming. Most flood deaths are due to flash floods.

This course will provide a better understanding of floods. With a better understand, you will be able to be better prepared to stay safe.
