SISTERS, Ore. (August 27, 2025) — The Flat Fire, burning approximately two miles northeast of Sisters, Oregon, is estimated at 23,261 acres after updated infrared (IR) mapping and is 7% contained.
Overnight, firefighters expanded upon progress made during the day. Crews improved established dozer and hand line; extended hose installations; and expanded mop-up inside the fire perimeter. Infrared (IR) was utilized by structural and wildland resources to identify and extinguish hidden hot spots near homes and around the fire perimeter.
Firefighters have been working around the clock to secure lines and prepare for hotter, drier, and windier conditions. Crews have made steady progress, strengthening established line, mopping up heat near structures, and completing miles of handline and dozer line. That work has put firefighters in a stronger position going into a period of critical fire weather. However, much remains to be done.
Warm weather, thunderstorms, and erratic winds will begin to test lines today. Gusts from the north and northwest are expected to challenge the eastern and southeastern fire line starting tomorrow.
On the eastern perimeter of the fire, foot patrols between the Flat Fire and Alder Springs burn scar continue to improve areas of line. The Lower Bridge Rangeland Fire Protection Association (RFPA) will help bolster resources along the eastern edge. RFPAs are volunteer organizations of local landowners trained to fight wildfires in rangeland areas. Structural crews will be working near Goodrich Road, extinguishing hot spots where winds have stirred up smoldering embers around homes.
On the southeastern perimeter, wildland crews continue working to complete hose lays ahead of wind that will challenge area lines. On the southwestern edge, structural and wildland resources are coordinating efforts to shore up protection of homes along the canyon rim. Along the western perimeter, crews have progressed to mopping up 150 feet inside the fire and are addressing overhead hazards caused by fire-damaged trees. Air support is available and is being utilized when needed, as weather allows.
