A Red Flag Warning is a weather warning issued by the National Weather Service for a select area. It is used to alert agencies to the high potential for development of a Red Flag event in the 12-72 hour time frame. The warning forecasts warm temperatures, low humidity in dried fuel moistures, and strong winds expected within 24 hours. The combination of these increased risks results in an increased risk for a wildland fire or rapid-fire growth if an incident were to occur. A Red Flag Warning means critical fire weather conditions are forecasted. The criteria for issuing a Red Flag Warning include:

• Sustained Wind average: Winds of 15 mph or greater are expected.
• Relative humidity: Humidity levels of less than or equal to 25 percent.
• Temperature: When temperatures rise above 75 degrees Fahrenheit.

Red Flag Warnings are usually only issued during the spring and fall fire weather seasons, February 15 – April 30 and October 1 - December 15. However, they can occur any time of the year. During a Red Flag Warning, it is important to follow the instructions provided by your local fire department and maintain a heightened awareness of anything that can generate a spark or flame. It is also important to be prepared to take action if a wildland fire develops in your area.
