2019 Severe Weather Awareness week for Pennsylvania is April 22–26. Plan ahead and stay weather aware for safe spring!
Our severe weather and weather safety topic for today is Flash Flooding and Flash Flood Safety.
A flash flood is a rapid flood. During a flash flood, a stream or creek will rise rapidly and crest generally within a few hours after the start of a heavy rain. Flash floods are dangerous because the waters rise so quickly that they can catch people
off guard and trap them in precarious situations. This is why the National Weather Service constantly monitors rainfall using rain gauges and radar estimates, as well as monitoring stream and creek levels using automated river gauges and local spotters.
Your National Weather Service will issue Flash Flood Watches and Flash Flood Warnings to help alert you to expected flood dangers.
Flash floods are caused when very heavy rainfall, usually from low-moving thunderstorms, overwhelms the natural or man-made drainage systems. Streams, creeks, and smaller rivers are most vulnerable to flash flooding. Flash flooding occurs in urban areas
as well as in rural areas.
A flood watch means that flooding may occur. Residents should stay alert, closely monitor rivers and streams, and be prepared to move to high ground quickly.
A flood warning means that there is actual flooding. Residents should act at once and move to high ground.
Flash floods occur within six hours of the beginning of heavy rainfall. Below are some guidelines for keeping safe during a flash flood:
