The National Fire Danger Rating System (NFDRS) is a quantitative
means for evaluating the fire danger across vast areas. This
complex model of fuel and weather parameters processes daily
weather observations and fuel moisture as input, and fire managers
receive numeric output danger over a given area area.
Fire Weather Station forecasts are routinely issued during the
fire season, which extends from February 15 through April 30, and
from October 1 through December 15. The station forecast
provides specific information on expected weather, temperature,
humidity, maximum and minimum values, and lightning activity
levels. The station forecast is issued only for Mammoth Cave, near
Bowling Green, Kentucky.
