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).

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-14 POES AVHRR LAC satellite images,
Left: Heat signatures (red) and smoke (light blue haze) are visible from fires burning in central Alaska. The Vinasale Fire (indicated by yellow arrow) has scorched approximately 49,600 acres and was zero percent contained. This information is from the National Interagency Fire Center Incident Management Situation Report from 5/30/2002
Middle: Heat signatures (red) and smoke (light blue haze) are visible from fires burning in Georgia. The Blackjack Bay Complex Fire (indicated by the yellow arrow) has burned approximately 110,631 acres on the Okefenokee National Wildlife Refuge and was 0% contained. This information is from the National Interagency Fire Center Incident Management Situation Report from 5/30/2002.
Right: A heat signature (red) and a smoke plume (light blue haze) are visible from the Bullock Fire burning 15 miles northeast of Tuscon, AZ. The Bullock Fire has scorched approximately 20,800 acres in Coronado National Forest and was 55% contained. This information is from the National Interagency Fire Center Incident Management Situation Report from 5/30/2002. The pink areas visible on the left side of the image are due to solar heating of the ground surface.

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 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.”
