Red Flag Warning

What does it mean?

A Red Flag Warning is a term used by fire-weather forecasters to call attention to limited weather conditions of particular importance that may result in extreme burning conditions. It is issued when the fire weather forecaster has a high degree of confidence that Red Flag criteria will occur within 24 hours of issuance

Red Flag criteria occur whenever a geographical area has been in a dry spell for a week or two, or a shower period, if before spring green-up or after fall color, and the National Fire Danger Rating System (NFDRS) is high to extreme, and the following forecast weather parameters are forecasted to be met:

1. A sustained wind average of 15 mph or greater

2. Relative humidity less than or equal to 25 percent

3. A temperature of greater than 75 degrees F

What You Should and Shouldn't Do

• Do not drive your vehicle onto dry grass or brush. Hot exhaust pipes and mufflers can start fires.
• Do not discard cigarette butts out of your car window.
• No open flames during red flag warning.
• Take extra precautions by checking and replacing spark arrestors on any vehicle or equipment with an internal combustion engine.
• Do not use a lawnmower in dry vegetation, especially when it's windy. Metal blades that strike rocks can create sparks and start fires.
• Review your family emergency plan, including evacuation routes, and have a go kit ready. 
• Follow local news & alerts for information and instructions in the event of an emergency.
