Red Flag Warnings

Red Flag Warning & Fire Weather Watches

The National Weather Service issues Red Flag Warnings & Fire Weather Watches to alert fire departments of the onset, or possible onset, of critical weather and dry conditions that could lead to rapid or dramatic increases in wildfire activity. 

A Red Flag Warning is issued for weather events which may result in extreme fire behavior that will occur within 24 hours. A Fire Weather Watch is issued when weather conditions could exist in the next 12-72 hours. A Red Flag Warning and Purple Warnings are 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. 

The type of weather patterns that can cause a watch or warning include low relative humidity, strong winds, dry fuels, the possibility of dry lightning strikes, or any combination of the above.

During heightened fire danger, Northstar Fire Department, Cal Fire, and other surrounding fire agencies will place additional firefighters on duty, staff more fire engines and keep more equipment on 24 hours a day to be able to respond to any new fires.

During Red Flag Warnings, residents and visitors are advised to:

  1. Use extreme caution to avoid sparking a wildfire
  2. The use of open flame appliances such as propane or natural gas fire pits and BBQs should be avoided. 
  3. Bring in all flammable items such as patio umbrellas, chair cushions, door mats, etc. to avoid ignite by wildfire embers.
  4. Be ready to go (Ready, Set, Go) in case a wildfire threatens their area. Northstar is located in NWS Zone 272.
