SISTERS, Ore.  — The Flat Fire, approximately two miles northeast of Sisters, Oregon, is estimated at 23,346 acres and is 52% contained. Despite critical fire weather, established fire lines have remained secure and suppression repair objectives continue across the incident. The Red Flag Warning is no longer in effect due to a lower chance of strong gusty winds. Hot, dry conditions persist. Today, firefighters will focus on restoring areas impacted by fire response efforts, such as repairing dozer lines and reducing erosion risks. These initiatives strengthen containment and protect the landscape to support long-term recovery. With a unified mission across the fire line, crews continue to make steady progress, bringing the incident closer to full suppression. Oregon State Fire Marshal (OSFM) resources have demobilized from the Flat Fire. Cooperative firefighting efforts from structural, wildland, and air resources protected homes through extreme fire activity and critical weather conditions.
