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)
Archived NICC Incident Management Reports (recent daily reports and archived daily reports 1994-1997) are provided by the Center for International Disaster Information (CIDI)
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).

The Florida Division of Forestry gives the following long-range Wildfire Season Forecast September – March 2002 for Florida:
“A return to near normal conditions in the equatorial Pacific Ocean marks the end of the prolonged La Niña event that brought very active fire seasons to the state the past few years. Normal to slightly warmer sea surface temperatures in the Pacific will bring us our first normal winter in a while, and if sea surface temperatures continue to slowly warm we may get above normal rainfall this winter.”
