Red Flag Warnings

A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly.  A combination of strong winds, low relative humidity, and warm temperatures can create extreme fire behavior.

The National Weather Service provides daily fire weather forecasts in close coordination with local fire agencies.  The Red Flag Warning Program enables firefighting agencies to manage critical resources and prepare appropriate suppression responses for protecting life and property.  Red Flag Warnings are typically issued within 24 hours of an impending critical fire weather event. 

Red Flag Warning Criteria

*  Relative humidity is 15% or less with either sustained winds of 25 mph or greater or frequent gusts of 35 mph or greater for a duration of 6 hours or more.
