|What are Red Flag Warnings & Fire Weather Watches?|
The National Weather Service (NWS) issues Red Flag Warnings & Fire Weather Watches to alert land management agencies about the onset, or possible onset, of critical weather and fuel moisture conditions that could lead to rapid or dramatic increases in wildfire activity. This could be due to low relative humidity, strong winds, dry fuels, or any combination thereof. You may have noticed that the Watch/Warning/Advisory map on our homepage turns red or orange when a Red Flag Warning or Fire Weather Watch is issued. Each year, the NWS coordinates with each state to implement a State Operating Plan related to fire weather services. Red flag criteria are set in these plans and vary from state to state. NWS Tallahassee serves portions of three states, each with their own red flag criteria. These criteria are summarized in the table below.
The Keetch-Byrum Drought Index (KBDI) is greater than or equal to 300, OR, the Alabama Forestry Commission has issued a Fire Alert.
A red flag warning is issued when the above conditions are expected to be met within the next 24 hours. A fire weather watch is issued when the above conditions are expected to be met during the next 24 to 48 hours. Typically, these watches and warnings are issued at the same time the routine fire weather forecasts are issued, 7:30 AM and 3:30 PM Local Time.
A glossary of fire weather terms is provided here for your reference.
