Fire Weather & Fire Danger Information TheWildland Fire Assessment System (WFAS) is a contribution of “The Fire Behavior Research Work Unit”, Missoula (Montana USA). The broad area component of the Wildland Fire Assessment System (WFAS) generates maps of selected fire weather and fire danger components.
Fire Danger (Potential) is a normalized adjective rating class across different fuel models and station locations. It is based on information provided by local station managers about the primary fuel model, fire danger index selected to reflect staffing level, and climatological class breakpoints. Low danger (Class 1) is green and extreme potential (Class 5) is red.

Dead fuel moisture responds solely to ambient environmental conditions and is critical in determining fire potential. Dead fuel moistures are classed by timelag.
10-HR Fuel Moisture
100-HR Fuel Moisture
1000-HR Fuel Moisture

The Keetch-Byram Drought Index (KBDI) is a soil/duff drought index. Factors in the index are maximum daily temperature, daily precipitation, antecedent precipitation, and annual precipitation. The index ranges from 0 (no drought) to 800 (extreme drought) (details).

Near-real time satellite images Operational Significant Event Imagery (OSEI) The following significant events were identified by Satellite Analysis Branch meteorologists and reviewed by the OSEI support team of the National Oceanic and Atmospheric Administration (NOAA):
NESDIS/OSEI NOAA-12 POES AVHRR LAC satellite image, 4 September 2001.
Left: Heat signatures (red) and smoke (light blue haze) are visible from fires burning in Montana. The Moose fire has burned 58,500 acres in Flathead National Forest and Glacier National Park 13 miles north of Whitefish and was 5% contained. The Bergsicker WRU Complex fire has burned 4,300 acres in Flathead National Forest 29 miles east of Bigfork was 0% contained. .
Right: Heat signatures (red) and smoke (light blue haze) are visible from fires burning in Idaho. The Willow Creek fire has burned 13,500 acres northeast of Fairfield and was 10% contained.

Long-range weather forecasts National Weather Service Long-range, 30-day weather forecasts are predicting above-normal temperatures for the southern tier of states from southern California to Florida and throughout the Midwest (see 30 and 90-day forecast maps).

The Florida Division of Forestry gives the following long-range outlook summary of the recent Fire Weather & Fire Danger Information for Florida (updated June, 2001): “Normal summer rainy pattern is developing across the state which will greatly reduce the wildfire threat. Current long-range forecasts offer little more than a guess that conditions will be near normal for the next several months. Several forecasts of Pacific ocean sea surface temperatures indicate a potential for a weak El Nino to develop for this winter, which would bring a wetter than normal winter.”
