Santa Ana Winds Drive Destructive Wildfires and Evacuations Across Southern California

The National Preparedness Level remains at Level 1 as local and regional resources generally meet suppression demand, even as season-to-date fire activity and total area burned continue to trend well above ten-year averages. While national potential for significant new blazes remains low, strong Santa Ana winds have prompted critical fire activity and regional preparedness surges across Southern California. Crews nationwide continue to manage uncontained blazes across the Northwest, Northern Rockies, and Upper Midwest alongside rapid-response operations in the Southwest.

Significant Fires

• Norte Fire (California) — Pushed by gusty offshore winds in Orange County, the fire spread rapidly into San Juan Capistrano neighborhoods, destroying multiple homes and forcing mandatory evacuations for thousands of residents. Emergency shelters are operating in San Juan Capistrano and San Clemente, with federal emergency funds approved to support containment efforts.
• Bryson Fire (California) — Igniting near Malibu in western Los Angeles County, the blaze threatened thousands of structures and forced neighborhood and institutional evacuations before ground and air crews halted its spread with no homes lost. Firefighters continue mopping up and strengthening containment lines as warm conditions persist.
• Henderson Fire (California) — Burning through grass and brush on Camp Pendleton in San Diego County, the wind-fanned fire briefly prompted the complete closure of Interstate 5 before highway lanes were reopened. Ground crews and aircraft continue working to secure perimeter lines and mitigate roadside smoke hazards.
• Sisi Fire (Washington) — Flanking toward the Stehekin River in the Okanogan-Wenatchee National Forest, the fire continues to threaten nearby residences under moderate burning behavior. Safety closures remain in place along Stehekin Valley Road and the Pacific Crest Trail.
• Ridge Fire (Michigan) — Burning northwest of Marquette in Michigan's Upper Peninsula, the fire is now managed under unified command within the Rugged Terrain Complex. Evacuation readiness advisories remain active for nearby residents, and local trail systems west of County Road 510 stay closed.
• PK Fire (Wyoming) — Suppression efforts west of Sheridan have made substantial progress following recent moisture, prompting county officials to lift all community evacuation notices. Crews are patrolling established containment lines and extinguishing interior heat.

Conditions and Outlook

Red Flag Warnings and Heat Advisories remain in effect through Saturday evening across coastal and valley portions of Southern California due to gusty Santa Ana winds and critically low humidity. Offshore winds will ease heading into Sunday, giving way to cooler onshore breezes, higher relative humidity, and improved conditions across the fire grounds into early next week. Elsewhere, autumn conditions across the Northwest, Northern Rockies, and Upper Midwest will keep significant fire potential low.

Burn Bans and Land Management

Public Safety Power Shutoffs have de-energized circuits across high-risk corridors in Southern California to reduce ignition risks from electrical equipment during high winds. Emergency trail and recreation closures remain active across portions of the Pacific Crest Trail in Washington and Craig Lake State Park in Michigan.

What Residents Should Do

• Heed all mandatory evacuation orders immediately and use designated evacuation corridors.
• Prepare for potential utility power shutoffs by securing backup power sources and emergency supplies.
• Refrain from all outdoor burning or any equipment use that could generate sparks during Red Flag conditions.
