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
    http://www.nifc.gov/fireinfo/nfn.html
  • Year-to-date State-by-State total number of wildland fires and area burned (table)
    http://www.nifc.gov/fireinfo/nfnmap.html
  • Daily locations of large fires (map)
    http://www.nifc.gov/fireinfo/firemap.html

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.

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
The Operational Significant Event Imagery (OSEI)
provided  a  NOAA-12 POES AVHRR  satellite image on 11 October 2001, showing heat signatures (red) and smoke (light blue haze) from fires burning in North Carolina and in Virginia.

The TOMS Global Aerosol Hot Spots Page provides screened close-ups of regions with active fires and smoke emissions. The latest available image is from 10 September 2001.

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.”
