The National Weather Service (NWS) in Los Angeles/Oxnard announced a Red Flag Warning that will be in effect from 10 a.m. Tuesday through 3 p.m. Friday. The warning covers many interior portions of Southwest California, where a hot, unstable air mass combined with locally gusty winds and very low humidity creates a high risk of large plume‑dominated fires that can spread rapidly.
Key weather details
Temperatures are expected to reach highs of 96° to 106°F in lower‑elevation areas, while higher mountain zones will see more moderate highs of 85° to 95°F. Overnight lows will sit in the mid‑70s to mid‑80s in the mountains and foothills.
Instability will be pronounced, with mixing heights of 12,000 to 18,000 feet from Tuesday through Thursday, dropping slightly on Friday. This deep mixing supports the development of strong up‑drafts that can feed fire growth.
Winds will come from the southwest at 10 to 20 mph, with gusts of 20 to 30 mph each afternoon into early evening. These gusts can carry embers long distances, igniting new fire fronts.
Relative humidity will be exceptionally low, with minimum values of 10 to 20 percent each day. Overnight recovery will be poor, especially in the mountains and foothills where humidity may only climb to 15 to 30 percent.
Potential impacts
The combination of heat, wind and dryness creates a “significant risk” of large plume‑dominated fires that can spread quickly and exhibit extreme fire behavior. Historical fire patterns show that this time of year often produces major fires under similar conditions, such as the Bridge, Bobcat and Station fires.
Residents living near wildland‑interface zones should take extra precautions. Any activity that could generate a spark—campfires, equipment use, fireworks, or even a discarded cigarette—should be avoided. Homeowners are urged to clear flammable vegetation from around structures, keep fire‑extinguishing tools handy, and stay informed of evacuation routes.

What to do if a fire starts
If a wildfire breaks out near your property, follow local emergency‑management instructions immediately. Evacuate when ordered, take only essential items, and keep your vehicle fueled. Stay tuned to local news stations and official social‑media channels for real‑time updates.
Authorities remind the public that a Red Flag Warning is a short‑term alert indicating that critical fire‑weather conditions are imminent. By exercising caution and preparing in advance, communities can reduce the likelihood of a catastrophic fire event.
