Red Flag Warning

What is a Red Flag Warning?

A Red Flag Warning is a forecast warning issued by the National Weather Service (NWS) to inform area firefighting and land management agencies that conditions are heightened for wildland fire ignition and rapid fire propagation.

When humidity is very low, and especially when high or erratic winds which may include lightning are a factor, the Red Flag Warning becomes a critical statement for firefighting agencies. Local fire agencies often increase their staffing and equipment resources to accommodate the forecast risk.

To the public, a Red Flag Warning means high fire danger with increased probability of a quickly spreading vegetation fire in the area within 24 hours.

Weather criteria for Fire Weather Watches and Red Flag Warnings are based on the local vegetation type, topography, and weather parameters such as relative humidity, wind and temperature. They usually include the daily vegetation moisture content calculations, expected afternoon high temperature, afternoon minimum relative humidity and daytime wind speed.

A separate but less imminent forecast may include a Fire Weather Watch, which is issued to alert fire, land management agencies, and the public to the possibility that Red Flag conditions may exist beyond the first forecast period (12 hours). The watch is issued generally 12 to 48 hours in advance of the expected conditions, but can be issued up to 72 hours in advance if the NWS agency is reasonably confident. The term “Fire Weather Watch” is headlined in the routine forecast and issued as a product. That watch then remains in effect until it expires, is canceled, or upgraded to a Red Flag Warning.

Santa Barbara County fire agencies initiate the Santa Barbara County Red Flag Warning Plan when notified by the NWS. It can be initiated in all areas of the County or only specific zones as defined by the Plan. There are 5 specific zones within SB County as 

  • Santa Barbara County South Coast - CAZ239
  • Santa Barbara County Central Coast - CAZ235
  • Santa Ynez Valley - CAZ236
  • Cuyama Valley - CAZ238
  • Santa Barbara County Mountains - CAZ252

Why does Santa Barbara County have a Red Flag Warning Plan?

Public notification/alert of potential fire danger is very important. Santa Barbara County has an extensive history of catastrophic wildfires. Because of this fire history fire agencies work in cooperation with the National Weather Service to predict the weather conditions that increase fire risk. The Red Flag Warning Plan provides a means for preparing for heightened wildfire situations.

Within Santa Barbara County a Red Flag Warning can also be initiated when local fire fighting resources have been depleted or if unusual circumstances exist that make fire suppression more difficult.

What happens when a Red Flag Warning is initiated?

• A symbolic red flag is raised at affected fire stations and in the Riviera and Eucalyptus Hill neighborhoods.
• Local media is advised and information is updated regularly.
• Santa Barbara City, Public Work places signs in key locations within the high fire hazard area.
• Any burn permits are cancelled, and all burning is banned.
• Fire agencies increase patrols in high fire hazard areas and increase the number of fire response personnel.
• Other agencies, such as Public Works. Parks and Law Enforcement are notified and may initiate additional  protection measures.
• Under extreme conditions Park events may be closed and fire closures may be issued on public lands and roadways.
• When a Red Flag Warning is no longer in affect it is officially’ Cancelled’ and notifications are made.
