Red Flag Warning: English

During Red Flag Warnings, extreme caution is urged for all residents because fires are more
likely to ignite, and those that do are more likely to spread rapidly and be more difficult to control

Red Flag Warning conditions are typically related to wind events lasting at least 8 hours.

During these events vegetation is very dry, humidity is low and no rain has occurred in the last 24 hours.

Relative humidity and wind speed are the primary factors driving a Red Flag Warning declaration.

Red Flag Warnings are designated for a specific span of time. The Warning remains in effect until it expires, is canceled or upgraded.

The first thing you should do during a Red Flag Warning event is to review your Wildfire Evacuation Checklist. Copies are available through FIRESafe MARIN and they can be downloaded from their website:
