Wildland Fire Update
The National Interagency Fire Center (NIFC) based in Boise (Idaho) provides key information on current wildland fire situations, related information and background materials. The following information is updated daily and can be accessed directly:
- State-by-State daily and year-to-date summary of fire activities
- Year-to-date State-by-State total number of wildland fires and area burned (table)
- Daily locations of large fires (map)
The National Interagency Coordination Center (NICC) provides daily situation reports. These reports include:
- Incident Management Situation Reports (fires and area burned reported to NICC). The files include current, previous and archived reports
- Prescribed Fire and Wildland Fire Use (year-to-date fires and area burned reported to NICC, posted weekly on Monday mornings)
Fire Weather & Fire Danger Information
The Wildland 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).

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.”
