Current Situation
Situation Summary
UPDATE- (11 a.m., Monday, Aug. 4): New mapping Monday morning shows it burned 401 acres. It remains at 40 percent contained. This is the largest wildfire in the CAL FIRE Sonoma-Lake-Napa Unit in 2025. Prior to this fire igniting Sunday afternoon, our Unit had only seen 240 wildfires burn a total of 518 acres. The previous largest wildfire in our Unit this year was the 111-acre Linda Fire north of Vacaville back on June 13. The CAL FIRE Sonoma-Lake-Napa Unit covers six counties in the North Bay Area - Sonoma, Lake, Napa, Solano, Yolo and Colusa.
Update (7 a.m., Monday, Aug. 4): Overnight firefighters contented with 15-20 mph winds but were able to keep the fire within its current footprint at 340 acres. The focus for Monday's operations will be to continue improving and strengthening the established control lines, mopping up the interior of the fire, mitigating any hazards on the site and providing for both public and emergency personnel safety at all times. Intel 12 is scheduled to be back over the fire to map its size and provide hot spot data to firefighters around 9 a.m. The damage assessment process will continue on Monday. One outbuilding was confirmed destroyed in the fire late Sunday with a second unverified structure having been known to be impacted. One firefighter was injured Sunday evening and was transported to a local hospital for evaluation and treatment of minor injuries. The investigation to determine the cause of the fire remains ongoing.
What Happened
The fire was exhibiting moderate to erratic fire behavior with short-range spotting, as the winds aligned with the topography in the early stages of the fire. Multiple structures were threatened with fire engines assigned to structure protection as evacuation orders and warnings were established. Airtankers concentrated at the head of the fire and established a fire-retardant line that was tied into the dozer and hand lines established on the left flank and left shoulder near Pond Road.
Assigned Resources
Numerous firefighting air tankers from throughout the State are flying fire suppression missions as conditions allow.
