USA: Fire Weather Forecasts of the Storm Prediction Center (SPC)


The Storm Prediction Center (SPC) is part of the National Weather Service (NWS) and the National Centers for Environmental Prediction (NCEP). The mission of SPC is to provide timely and accurate forecasts and watches for severe thunderstorms and tornadoes over the contiguous United States. The SPC also monitors heavy rain, heavy snow, and fire weather events across the U.S. and issues specific products for those hazards. SPC uses the most advanced technology and scientific methods available to achieve this goal.

Fire Weather Outlooks
http://www.spc.noaa.gov/products/fire_wx/index.html
The purpose of the SPC Fire Weather Outlooks and meteorological Risk Categories are to indicate areas where dry dead fuels such as dry grass and dry timber and meteorological conditions (wind, relative humidity, temperature, and dry thunderstorms) might contribute to potentially dangerous wild fire behavior. The SPC does not forecast local meteorological conditions (i.e. local variability of relative humidity or the effects of terrain on wind direction and speed). In addition, slope of local terrain, types of fuels (fuel model), variability of fuels, and l ive fuel moisture content are not considered in detail.
