A wildfire burning through the rugged national forest land above California’s Big Sur coastline reached 29,768 acres over the weekend, and containment has moved fast in the days since. The Plaskett Fire, burning in the Los Padres National Forest in Monterey County, started on August 26 and has forced a stretch of Highway 1 to close in both directions. Steep terrain and heavy vegetation have slowed crews even as favorable weather has helped them lock down more of the perimeter. The fire exploded in size during its first week, growing from roughly 15,478 acres on August 30 to 26,734 acres by the morning of September 1 while containment sat at just 1 percent, before the growth rate finally began to level off.
Steep terrain and heavy chaparral slow the advance on containment lines
According to CAL FIRE’s incident page, crews have spent recent days strengthening both direct and indirect control lines while conducting strategic firing operations to remove unburned fuel ahead of the fire’s edge. Rotary- and fixed-wing aircraft have supported that work with retardant drops, but officials say steep, rugged terrain and limited road access continue to challenge suppression operations across the fire’s footprint on federal land managed by the U.S. Forest Service. Personnel assigned to the incident grew alongside the fire itself, climbing from fewer than 900 firefighters in the fire’s first days to a Type 1 incident management team overseeing close to 2,000 personnel as the effort shifted from initial attack to sustained containment work in steep, hard-to-reach drainages roughly 34 miles southwest of Big Sur.
A stretch of Highway 1 shut down in both directions
The fire has closed Highway 1 in both directions between mile marker 19 at the Kirk Creek Campground on the north end and mile marker 0.0 at the Monterey and San Luis Obispo county line on the south end. CAL FIRE has warned drivers to avoid the corridor entirely while emergency crews continue active operations nearby, and the closure has remained in place through the most recent incident updates.
Evacuation orders holding across Monterey County and Fort Hunter Liggett
Evacuation orders and warnings remain in effect across portions of Monterey County and the Fort Hunter Liggett military training area, while San Luis Obispo County residents to the south remain under evacuation warnings rather than orders. Structure defense and protection of critical infrastructure have been listed as top priorities throughout the incident, reflecting the presence of homes and ranch buildings scattered through the fire’s path along the coastal mountains. CAL FIRE’s updates have repeatedly cited the region’s steep, rugged terrain and heavy vegetation as ongoing challenges even as containment has improved, and evacuation orders and warnings have stayed in place across the same footprint through each of the incident’s recent updates. CAL FIRE has directed residents to the county’s Genasys Protect zone-lookup tool to check their specific evacuation status rather than relying on general reports of the fire’s footprint.
Containment climbs from 23 percent to 47 percent in two days
When CAL FIRE recorded the fire at 29,768 acres, containment stood at 23 percent. Growth has since slowed to a crawl, with the mapped footprint edging up to 29,862 acres, while containment has climbed far faster, reaching 37 percent by Monday morning and 47 percent by Monday evening, the most recent update available. That pattern, acreage essentially flat while the contained percentage more than doubles, indicates crews have been securing line around a fire that has largely stopped spreading rather than racing to keep up with new growth.
Two fires and one smoke outlook along the Big Sur coastline
The Plaskett Fire has been burning at the same time as the smaller Timber Fire farther north along the same stretch of coast, and CAL FIRE has issued a joint smoke outlook covering both incidents for Central California communities downwind. The overlap has complicated air-quality conditions across the region even as containment gains reduce the immediate threat to structures near the fire lines. Together, the two fires have burned tens of thousands of acres along the Big Sur coast this fire season, with the Plaskett Fire overtaking the Timber Fire in total footprint after starting more than a week later, a reflection of how quickly fire can spread through the area’s steep, chaparral-covered slopes once conditions align.
A virtual community meeting to address containment and the highway closure
The Los Padres National Forest, working with the California Interagency Incident Management Team overseeing the response, held a virtual community meeting Tuesday evening to update residents on containment progress, evacuation status and the ongoing Highway 1 closure. Officials from the Forest Service, Fort Hunter Liggett Fire Department and cooperating agencies took part, giving residents a chance to ask questions directly as firefighters continue to strengthen lines around the fire’s perimeter. Meetings of this kind have become a routine part of the response as the incident has stretched into its second week, giving evacuees and Highway 1 travelers a regular channel for updates beyond the written incident reports CAL FIRE and the Forest Service post throughout each day. The incident’s public information line and a dedicated email address have stayed active alongside the meetings, a reflection of how much day-to-day interest the closure and evacuations have generated among residents and travelers who rely on Highway 1 as their main route along this stretch of coast.
