NWS Jackson NFDRS Fire Danger Forecast

NFDRS Single Station Forecasts

This product measures wildfire danger at RAW Sites. NFDRS observations are taken once per day. NFDRS forecasts are not intended to be site specific, but an overview of the general fire danger. Effective fire suppression planning depends heavily on NFDRS, because it is an objective tool for predicting the difficulty of suppression a wild fire. The NWS role in NFDRS is forecasting weather input which, combined with customer input, allows NFDRS software to predict the next day's fire danger indices. Daily weather observations entered into NFDRS by the fire agencies form the basis of the forecast input by the NWS. Each NFDRS site is located at a spot which is representative of the terrain and fuel types dominant in that area.
