Flash
Flood Monitoring Prediction System at the National Weather Service
in Caribou, Maine
By: Joseph Hewitt
Senior Forecaster
The National Weather Service has
developed a new monitoring system that will help forecasters with early
detection of flash flooding. This new system is called the Flash Flood
Monitoring and Prediction system or otherwise known as FFMP. This new Flash
Flood Monitoring and Prediction system was used as a forecast and warning tool
for the first time this year 2003 at the National Weather Service in
Caribou.
FFMP allows a forecaster to inspect
either a county or the forecaster can choose to look at a particular
river/stream basin within a particular county. FFMP detects, analyzes, and
monitors rainfall every 5 minutes from the WSR 88D Doppler radar system and
generates short term warning guidance on flash flood potential automatically to
the forecaster. This allows the forecaster to assess the information and decide
whether or not to issue a flash flood warning or a flash flood statement.
The benefits to this new flash
flood monitoring system are: 1) the forecaster can zero in on a particular
stream basin that is receiving heavy rainfall and investigate that stream basin,
2) the forecaster will have longer lead times on flash flood warnings , 3) the
longer lead times in flash flood warnings will allow the public, public
officials and law enforcement to act accordingly.
The bottom line is that the
National Weather Service’s mission is to save lives and protect property. The
Flash Flood Monitoring and Prediction system or FFMP will help the National
Weather Service to accomplish this
mission.
