What is a Red Flag Warning?

A Warning issued by National Weather Service fire weather forecasters to alert forecast users to an ongoing or imminent critical fire weather pattern. The warning product alerts land management agencies to the potential for widespread new ignitions or control problems with existing fires, both of which could pose a threat to life and property.

It is issued when it is an on-going event or the fire weather forecaster has a high degree of confidence that Red Flag criteria will occur within 48 hours of issuance. Red Flag criteria is based on local area vegetation characteristics, local climatology, select weather criteria and/or any combination of critical weather and fuel moisture forecasts. In some states, dry lightning and unstable air are criteria. A Fire Weather Watch may be issued prior to the Red Flag Warning.
