Flash flooding is one of the most dangerous forms of changing weather. Along with lightning and tornadoes, flash floods are responsible for a high percentage of weather storm deaths. Flash flooding and lightning deaths tend to not get as much media coverage as compared to tornado deaths but flash flooding and lightning are serious weather related risks.

Flash flooding is a sudden rise in water level within creeks, streams and other low lying water flowing regions. The rush of the water and the turbulence of the water make it difficult to survive when a person on foot or in a car is trapped in the rushing water. It is important to not drive through water of unknown depth and to seek higher ground when thunderstorms occur. When visiting or moving to an unfamiliar area, it is important to locate the regions that could be influenced by flash flooding. These areas should be avoided when heavy rain occurs, whether on foot or driving.

A flash flood can change a dry creek bed into a rushing torrent of water. The creek or stream can flash flood even if it is not raining at that particular location since the water source can be from a nearby thunderstorm. Flash flood watches and warnings are issued when the weather has the potential to generate heavy rain that can produce flooding. Being at a safe location, higher ground or home instead of driving can reduce the risks from flash flooding.
