What is a red flag warning?

Red Flag Warnings are issued by the National Weather Service when weather conditions are right for extreme wildfire events. These are days with sustained or gusty winds, and hot and dry conditions that make wildfires more likely to ignite and spread rapidly.

Red Flag Warning vs Fire Weather Watch

A Red Flag Warning is issued for weather events which may result in extreme fire behavior that will generally occur within 24 hours. A Fire Weather Watch is issued to advise agencies of the possible development of red flag conditions in the near future, generally the next 24 to 72 hours. A Red Flag Warning is the highest alert. During these times extreme caution is urged by all residents because a simple spark can cause a major wildfire. A Fire Weather Watch is one level below a warning, but fire danger is still high.

What To Do During a Red Flag Warning

• Review your family evacuation plan
• Ensure your go kits are stocked and ready
• Ensure your car has a full tank or is fully charged
• Ensure your cell phone is charged
• Prepare your home by removing combustibles within 5 feet of structures
• Monitor community alerts
