Many semi-empirical fire spread equations, as in those published by the USDA Forest Service, [7] Forestry Canada, [8] Nobel, Bary, and Gill, [9] and Cheney, Gould, and Catchpole [10] for Australasian fuel complexes have been developed for quick estimation of fundamental parameters of interest such as fire spread rate, flame length, and fireline ...
Spread Component – Displays a value numerically equivalent to the predicted forward rate of spread of a head fire in feet per minute. It is a function of fuel model characteristics, live fuel moistures , the 0 to 3-inch (76 mm) dead fuel moisture (heavily weighted to the 1-hour timelag fuels), wind speed and slope class .
Progression of a well-anticipated extremely critical event across the Central Plains on March 6, 2017. This event produced wildfires that burned 1,200,000 acres of land, and killed seven people. An extremely critical fire weather event is the greatest threat level issued by the NWS Storm Prediction Center (SPC) for wildfire events in the United ...
A high risk severe weather event is the greatest threat level issued by the Storm Prediction Center (SPC) for convective weather events in the United States. On the scale from one to five, a high risk is a level five; thus, high risks are issued only when forecasters at the SPC are confident of a major severe weather outbreak.

The Storm Prediction Center (SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), [1] which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC).
The Eaton Fire, which has burned around 14,000 acres in northern LA County, was 91% contained. The Hughes Fire forced officials to close a 30-mile stretch of the 5 freeway in both directions as ...
Daily Fire Weather Index forecast. The Forest fire weather index (FWI) (French: indice forêt météo, IFM) is an estimation of the risk of wildfire computed by Météo France and the Meteorological Service of Canada. It was introduced in France in 1992 but is based on a Canadian empirical model developed and widely used since 1976. [1]
