The National Weather Service issues Red Flag Warnings 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. Firefighters will raise red flags at fire stations to warn residents of extreme fire weather, as warnings are issued by the National Weather Service.

A Red Flag Warning is the highest alert. During these times extreme caution is urged by all residents, because a simple spark can cause a major wildfire.

Pay attention to weather conditions. Fire threat is highest on dry, windy days. When the National Weather Service issues a "Red Flag Warning" we will fly red flags on Fire Station flagpoles and send an AC Alert notification. During a Red Flag Warning, avoid any activities that could cause a spark and make sure your household is ready to rapidly evacuate.

What Precautions Is OFD Taking on Red Flag Days?

In addition to the Oakland Fire Department’s normal operations, on Red Flag days, the Department upstaffs and conducts roving fire patrols in the Oakland's High Fire Hazard Severity Zone. These additional resources augment the department’s normal hill company patrols that are out during the periods of high fire danger season.

In the lead up to and during Red Flag events, Oakland Fire collaborates with fire agencies from throughout the region regarding mutual aid planning preparedness.

Park & Lookout Closures and Precautions

Joaquin Miller Park is Closed on all Red Flag Days. The park closure shall be lifted once the Red Flag conditions have subsided and the National Weather Service has lifted the warning for our regional area. Depending on the current conditions and staffing capacity, the East Bay Regional Parks are often also closed during Red Flag events.

All vehicle traffic is prohibited from stopping at all lookouts and turnouts on Grizzly Peak between 9pm and 6am. Cars parked illegally at these locations during these hours are subject to citation.

Barbeques are prohibited in all City parks when there is a Red Flag warning in effect.
