NWCG Guide to Fire Weather Forecasts, PMS 425

The NWCG Guide to Fire Weather Forecasts leverages knowledge gained in S-190, Introduction to Wildland Fire Behavior, and S-290, Intermediate Wildland Fire Behavior. This publication is designed 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, the NWCG Guide to Fire Weather Forecasts establishes mandatory and optional fire weather forecast variables for Incident Fire Weather Forecasts as produced by Incident Meteorologists (IMETs).

The NWCG Guide to Fire Weather Forecasts supplements Agriculture Handbook 360: Fire Weather: A Guide for Application of Meteorological Information to Forest Fire Control Operations, PMS 425-1. Whereas the Agriculture Handbook 360 gives detailed information on fire weather and meteorological processes, this guidebook describes the fire weather forecast itself.

The NWCG Guide to Fire Weather Forecasts is developed and maintained by the Fire Weather Subcommittee (FWS), under the direction of the Fire Environment Committee (FENC), an entity of the National Wildfire Coordinating Group (NWCG).  The original content of this publication was developed through the contributions of Darren Clabo, South Dakota State Fire Meteorologist, in coordination with the FWS.

While they may still contain current or useful information, previous editions are obsolete.  The user of this information is responsible for confirming that they have the most up-to-date version.  NWCG is the sole source for the publication.

Comments, questions, and recommendations shall be submitted to the appropriate agency program manager assigned to the FWS.  View the complete roster.

  2. Fire Weather Forecast Variables
  3. Types of Fire Weather Forecasts

The National Wildfire Coordinating Group (NWCG) provides national leadership to enable interoperable wildland fire operations among federal, state, tribal, territorial, and local partners. NWCG operations standards are interagency by design; they are developed with the intent of universal adoption by the member agencies. However, the decision to adopt and utilize them is made independently by the individual member agencies and communicated through their respective directives systems.
