Flash Flood Guidance is an estimate of the amount of rainfall required over a given area
during a given duration to cause small streams to flood. These estimates are based on the current
soil moisture and stream flow conditions for the area. Flash Flood Guidance is routinely issued by National Weather Service (NWS) River Forecast Centers, and is used by NWS Weather
Forecast Offices when issuing Flash Flood Watches and Warnings to the public. Note: Less rainfall is required to produce flash flooding in urban areas.
The Northeast River Forecast Center uses a gridded Flash Flood Guidance System. If you have any questions regarding Flash Flood Guidance, please contact David Vallee, Hydrologist-in-Charge at 508-824-5116 x232 or David.Vallee@noaa.gov.
