Washington State's 2026 wildfire season remains severe, with 14 large fires actively burning as of August 29 and the Governor's statewide wildfire emergency — declared August 1 — still in effect. The state is navigating its most significant fire year in recent memory, driven by extraordinary drought, record heat, and destructive wind events that struck in late July and early August.

Sinlahekin Fire: Washington's Largest Active Incident

The Sinlahekin Fire in Okanogan County, burning northwest of Sinlahekin Campground near Tonasket, stands as Washington's largest active fire at more than 163,000 acres and approximately 49% containment. The fire has demanded substantial interagency resources and driven evacuation orders in the Okanogan Highlands region. Air tankers and crews from across the country have been deployed to support local firefighting forces.

Little Giant Fire Challenges Chelan County

The Little Giant Fire in Chelan County has burned 156,448 acres and remains at just 25% containment, making it one of the most challenging active incidents in the state. Steep terrain, dense fuels, and variable winds have complicated containment efforts. Crews have worked to protect structures and critical infrastructure throughout the fire's lengthy run.

Kaiser Canyon Fire Nearing Full Containment

In a more encouraging development, the Kaiser Canyon Fire in Okanogan County — which earlier in the season prompted widespread evacuations when it exploded to tens of thousands of acres under extreme fire weather — is now 138,293 acres at approximately 98% containment. The Storm Prediction Center issued a rare Extremely Critical Risk fire weather outlook for eastern Washington in early August around the time this fire was at its most dangerous, also resulting in the issuance of what meteorologists described as the first-ever Particularly Dangerous Situation (PDS) Red Flag Warning in the region.

Ptarmigan Fire Also Active in Okanogan County

The Ptarmigan Fire is also burning in Okanogan County, adding to the resource demands in an already heavily stressed geographic area. Fire managers with the Northwest Interagency Coordination Center (NWCC) have worked to balance resource allocation across multiple simultaneous incidents throughout the region.

Spokane Complex: Recovery Under Way

While no longer considered an active large fire, the Spokane Complex — described by officials as the worst natural disaster the Spokane area has ever faced — continues to have profound impacts on the community. The fires, which struck in early August during the same extreme fire weather event, burned through residential neighborhoods and prompted mass evacuations. Most evacuees have now been allowed to return to their homes, though toxicologists and emergency managers warn that burn zones still present hazardous material concerns. EPA hazmat teams have cleared approximately one-third of affected properties of hazardous household materials in what officials describe as an unprecedented pace of remediation.

Statewide Burn Ban Remains in Effect

Governor Ferguson's August 1 emergency declaration included a statewide burn ban that remains in effect due to ongoing dry conditions and elevated fire danger. The Washington Department of Natural Resources continues to coordinate with the NWCC and federal agencies to manage ongoing incidents and prepare for potential new starts as the season continues through September.

Residents throughout eastern Washington are urged to sign up for county alert systems, maintain defensible space around their properties, and follow official guidance from local emergency management offices regarding evacuation zones and access restrictions.
