Flash Flood Guidance



Flash Flood Guidance

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 issued by Northeast River Forecast Center.

Flash Flood Guidance Graphics

Probabilistic Guidance

This product provides a probabilistic forecast of rainfall over the continental United States in 6-hour and 24-hour increments issued by the Weather Prediction Center.

Probabilistic Guidance


Excessive Rainfall

The Excessive Rainfall graphics provide a forecast of the potential for flash flooding across the continental United States.


Excessive Rainfall Discussion



Mesoscale Precipitation Discussions

Provide short term guidance during heavy rain events leading to a threat of flash flooding to the NWS Weather Forecast Offices, River Forecast Centers, the media, emergency managers and interested partners.


Meteorological Model Ensemble River  Forecasts (MMEFS)

The purpose is to provide users with a short-term situational awareness by providing the probabilistic exceedence information relative to NWS flood categories and providing the ensemble river forecasts that in turn show a range of outcomes.
