The NWCG Guide to Fire Weather Forecasts, PMS 425, is for firefighters at all experience levels and for early- to mid-career fire weather meteorologists to guide them on the field expectations of their forecasts. Furthermore, it establishes mandatory and optional fire weather forecast variables for Incident Fire Weather Forecasts as produced by Incident Meteorologists (IMETs).
The content of Fire Weather, PMS 425-1, is now available for reference electronically. This guide, originally published in 1970, gives detailed information on fire weather and meteorological processes.
