This Pennsylvania Severe Weather Awareness
Week web briefing is brought to you by the National Weather Service in State College.
The week of March 3rd through March 7th has been designated as Severe Weather Awareness
Week in Pennsylvania. Each day, a different topic will be addressed to highlight significant
severe weather hazards and safety precautions to take when severe weather strikes.
Today’s topic is flash flooding. We will explain the definition of a flash flood, the
difference between a flash flood watch and a flash flood warning, and give safety tips
on what to do when a flash flood watch or warning is issued for your location. A flash flood is a sudden and violent life-threatening
flood, typically resulting from intense rainfall over a short period of time. The majority
of flash floods in Pennsylvania are caused by slow-moving thunderstorms or tropical rainfall.
Ice jams and snowmelt can also lead to flash flooding.
A flash flood watch gives you advance notice that conditions are favorable for flash flooding.
It does not mean flooding will occur, but it is possible. When a flash flood watch is
issued for your location, be sure to stay alert for changing weather conditions. If
you live in a flood prone area, be prepared to move to higher ground. A flash flood warning
is issued when flash flooding is imminent or occurring. Now is the time to take action!
Each year, more deaths occur due to flooding than from any other severe weather related
hazard. Over half of all flood-related deaths occur when a vehicle is driven into flood
waters. Always remember, if you encounter a flooded roadway, Turn Around, Don’t Drown!
