SISTERS, Ore. (August 24, 2025) — Overnight, firefighters continued to aggressively fight the 21,971-acre Flat Fire two miles northeast of Sisters, Oregon. Firefighters have been fighting the fire around the clock since Thursday afternoon.
Night shift crews were able to establish initial dozer and hand lines around portions of the fire. Notably, crews established initial lines along the southern head of the fire and made additional progress along portions of the north and west perimeter of the fire. Crews were also able to burnout unburnt vegetation in the Carcass Creek area to slow the fire’s spread.
Oregon State Fire Marshal (OSFM) firefighters remained engaged in residential areas throughout the south and southwestern portions of the fire, as well as Crooked River Ranch, suppressing fires around structures, extinguishing hot spots around homes and monitoring for embers.
“We were able to cut in some rough breaks around the fire to stop the spread around key areas and homes,” said Eric Perkins, Oregon Department of Forestry Complex Incident Management Team 3 Operations Section Chief. “We still have a lot of work ahead of us to improve lines and tie them together. We’re fighting this fire aggressively and safely, in cooperation with a lot of partners to saves homes in these communities.”
Today, firefighters will continue to face difficult terrain along with a red-flag warning today for hot conditions, combined with low relative humidities and an unstable air mass, with temperatures expected to reach triple digits. Ground crews will continue to work closely with air resources in an attempt to slow the fire’s forward progress, with a focus on protecting threatened structures.
OSFM structural task forces continue to focus efforts on homes in areas where the fire is most active. Type I strike teams have arrived and are dedicated to residential areas, reinforcing protection around homes and critical infrastructure. Where the fire front has passed, firefighters will be mopping up, extinguishing hot spots, and patrolling. “With the challenging weather conditions and changing winds, firefighter coordinated extremely well with all resources in the air and on the ground, defending homes and properties. The teamwork that is going on here is very streamlined.” Said Damon Schulze, Field Operations Chief for the Red Team.
