SISTERS, Ore. (August 25, 2025) — As of this morning, the Flat Fire is estimated at 21,971 acres with 5% containment. The fire is burning approximately two miles northeast of Sisters, Oregon.
Last night, firefighters took advantage of reduced fire activity and cooler temperatures to make significant progress. Along the northeastern and eastern perimeter of the fire, wildland resources completed dozer line and patrolled for hot spots. On the southeastern edge, crews reinforced established line and extinguished hot spots. In the south and southwestern areas, where the fire has been very active, wildland crews were able to fully line an approximately 10-acre slop over that occurred yesterday evening. The western perimeter was fully lined utilizing dozers, as was a spot fire that occurred yesterday near the northwestern edge of the fire.
Today, crews will build upon the significant work completed during the night – holding, securing, and expanding that progress. Wildland crews will be reinforcing established line, extinguishing hot spots, and continuing to quickly attack any slop over or spot fires should they occur. Structural resources remain positioned at homes throughout threatened areas, providing point protection and extinguishing hot spots. On the north end, structure crews continue to patrol for hot spots and engage in structural protection as necessary.
Despite precipitation occurring this morning, fuels remain dry. There is a Red Flag warning through 9 pm tonight and a heat advisory remains in effect through Wednesday. There is also a chance for thunderstorms in the forecast, which could result in strong, erratic winds with gusts up to 35 mph.
The Flat Fire has unfortunately resulted in the loss of four homes and several outbuildings in Deschutes County, and our thoughts are with those impacted. While any loss is difficult, hundreds of homes in the fire’s path remain standing – reflecting both the preparation property owners put into creating defensible space and the coordinated aggressive suppression efforts. Emergency management personnel continue to assess the area and notify property owners when a damaged structure is identified. County officials will share updates if the number of damaged or destroyed structures changes.
Incident officials will host a community meeting tonight, Monday, August 25th, starting at 6:00 pm at the Sisters High School, located at 1700 W McKinney Butte Rd. Local and incident officials will provide a fire update and answer questions from the community. The meeting will be streamed virtually via the Sisters-Camp Sherman Fire Department Facebook page.
