Red Flag Program

Latest Fire Weather Watch / Red Flag Warning

Fire Weather Watches and Red Flag Warnings are issued when the combination of dry fuels and weather conditions support extreme fire danger and/or fire behavior. These conditions alert 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.  A Red Flag event is the combination of critical meteorological fire weather conditions coinciding with significantly dry fuels. This combination can lead to the occurrence of large and dangerous wildfires. Since the potential for Red Flag conditions does not exist without receptive fuel conditions, knowledge of existing fuel conditions is essential.     

 

Red Flag
 Criteria

Vegetation Stage I or II
cured/transition - Spring/Fall

Vegetation Stage III
   green - Summer

Relative Humidity Less than 30% Less than 30%
Rainfall Less than 1/4 inch in previous 5 days Less than 1/4 inch in previous 8 days
Wind

Sustained or frequent gusts above 25 mph

Sustained or frequent gusts above 25 mph

 

Fuel N/A Keetch-Byram Drought Index above 300
Temperature Greater than 50 degrees F Greater than 50 degrees F

                                                                            
 

Fire Weather Watch is issued 12 - 96 hours in advance of expected onset of red flag criteria

 

Red Flag Warning is issued when red flag criteria will occur in 48 hours or less

 

Special Weather Statement is issued when conditions support enhanced fire weather behavior, but at levels below Red Flag criteria. SPSs can also be issued to raise elevated fire awareness amongst the fire weather community and the general public.
