Red Flag Warnings

COSCA trails may also be closed during "Red Flag" fire weather. The National Weather Service issues Red Flag warnings when the potential for fire becomes high in Southern California. Fire potential increases when the following conditions occur:

  • Hot, dry weather

  • Low relative humidity, at or below 15%
  • Abundant dry vegetation

During Red Flag conditions please be aware of your surroundings and keep an eye out for smoke. If you see smoke, please report it! Also, always let someone know your whereabouts, and be prepared to evacuate quickly.

During Red Flag Warnings please adhere to the following guidelines:

  • No smoking.
  • No fire of any kind.
  • Curtail any work that will involve equipment that can spark a fire.
  • Keep fire suppression equipment, shovels, fire extinguishers and/or garden hoses handy and in good condition.
