Woodacre, CA – The U.S. National Weather Service has issued a Red Flag Warning for Marin County that is in effect from 5 AM Saturday, October 28, through 5 PM Sunday, October 29. The warning supersedes a Fire Weather Watch that previously was in effect. Local fire agencies will be up-staffing throughout Marin County.

Graphic says Marin County Fire Chiefs Red Flag WarningErratic gusty winds may result in dangerous and unpredictable fire behavior during a Red Flag Warning.

A Red Flag Warning means that critical fire weather conditions are expected during the designated time frame. Fire conditions include a combination of strong offshore wind gusts up to 45 mph and low relative humidity ranging from 15-25%. The affected areas for this Red Flag Warning include the entire Marin County as well as neighboring counties of Sonoma and Napa.

The concern with this weather system is that wildfires that develop have the potential to spread rapidly. Erratic gusty winds may result in dangerous and unpredictable fire behavior. A simple spark could cause a major wildfire. The community is advised to exercise extreme caution.

Safety tips:

  • Avoid using barbecues or fire pits outdoors.
  • Avoid using any source of heat or open flame outdoors
  • Avoid using power tools (gas or electric), or mowers.
  • Properly discard cigarettes.
  • Keep vehicles off dry grass or vegetation.
