A Severe Red Flag Warning is in effect in California through 12 October 2026, 05:00, affecting South-Central Shasta County Including Redding Metro; Northern Sacramento Valley in Tehama County; Central Glenn County Including Interstate 5. The alert was issued October 11 at 7:38AM PDT and is in effect from 11 October 2026, 07:38 until 12 October 2026, 05:00.
By definition, a Red Flag Warning means critical fire weather conditions may occur. Conditions could include a combination of strong winds and low relative humidity that is expected to contribute to extreme fire behavior. The National Weather Service (NWS) identifies the affected fire weather zones as 124, 142, and 144.
The official description notes north to northeast winds 15 to 25 mph with gusts up to 30-40 mph, and relative humidity between 15 to 25 percent. Any fires that develop could spread rapidly and outdoor burning is not recommended, the NWS says.
For safety, call 911 in an emergency and monitor NWS, local authorities, or emergency services for updates. Be prepared to avoid outdoor burning and open flames, properly discard cigarettes, and maintain defensible space by clearing dry vegetation. Have multiple ways to receive information from authorities and be ready to relocate if local officials advise evacuation.
