The fast-moving Henderson Fire on Marine Corps Base Camp Pendleton burned more than 2,000 acres by Friday, October 16, 2026. The blaze forced a temporary shutdown of Interstate 5 and triggered base evacuations. Driven by strong easterly winds and high heat, the wildfire started shortly before 2 p.m. on Thursday near Basilone and Las Pulgas roads in the western part of the military installation.
Rapid Spread and Freeway Disruptions
Fueled by dry winds, the blaze charred roughly 400 acres within its first 90 minutes. By Thursday evening, the burn zone expanded past 1,000 acres with 0% containment. Ground crews and firefighting aircraft worked to stop its westward movement toward populated areas and power lines.
The worsening conditions caused major transportation disruptions across Southern California:
- Interstate 5 Closures: Authorities closed I-5 in both directions around noon on Friday between Vandergrift Boulevard and Basilone Road after a spot fire broke out near the perimeter. This followed an earlier closure during Thursday evening’s commute when heavy smoke blocked visibility.
- Roadway Restrictions: Officials closed Las Pulgas Road between Brown Street and Stuart Mesa Road. They also restricted the Las Pulgas Gate to emergency vehicles only.
- Transit Impacts: A separate brush fire near the San Onofre checkpoint also halted train service between Orange County and San Diego.
Evacuations and Containment Efforts
Cal Fire ordered mandatory evacuations for residents and personnel in the Las Flores (41 Area) of the base. Temporary evacuation points opened at Paige Field House (1110 13th St., Oceanside) and the 21 Area Fitness Center (210750, Oceanside). Although some initial evacuation orders were briefly lifted on Thursday evening, new flare-ups and spot fires required continuous emergency responses.
County air quality officials warned drivers and residents in North County to expect heavy smoke. By Friday afternoon, fire crews and state agencies were still fighting the blaze in difficult weather. No injuries or structural damage were reported, and the cause of the Henderson Fire is under investigation.
