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)
The National Wildfire Information Interagency provides detailed information on each individual state with active fires.
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/duffdrought index. Factors in the index are maximum daily temperature, dailyprecipitation, antecedent precipitation, and annual precipitation. The indexranges from 0 (no drought) to 800 (extreme drought) (details).

OperationalSignificant Event Imagery (OSEI)
The following significant event was identified by Satellite Analysis Branchmeteorologists and reviewed by the OSEI support team of the National Oceanic andAtmospheric Administration (NOAA):

Right: Heat signatures (red) and smoke (light blue haze) are visible from fires burning in California
Left: A big heat signature (red) is visible from a fire burning in California. The Willams Fire has charred 750 acres in Angeles National Forest and was 0% contained. This information is from the National Interagency Fire Center Incident Management Situation Report from 09/24/2002.

In the San Gabriel Mountains northeast of Los Angeles, a fast-moving fire is burning in the Angeles National Forest. The Williams Fire began on Sunday evening, September 22, 2002, and has already affected at least 2,500 acres. Roads into the area are closed to non-residents as firefighters tackle the blaze. Humidity is low, temperatures are high, and fire activity has been labeled extreme, with the fire perimeter increasingly rapidly and flame lengths high.(source: NASA’S Earth Observatory)

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).
