As of August 19, 2026, the Pacific Northwest continues to hold the grim distinction of being the most active wildfire region in the United States. The National Interagency Fire Center (NIFC) reports 34 uncontained large fires burning across Oregon, Washington, and Idaho — the highest concentration of active large fires of any geographic area in the country.

The Scope of the 2026 Fire Season

Nationwide, firefighters are currently working to contain 76 uncontained large fires, with 29,509 personnel assigned to incidents across the country. Oregon alone accounts for 21 of those large fires, Washington has 12, and Idaho is managing 5. Montana is also experiencing significant fire activity with 9 large fires.

The 2026 fire season has already shattered records. From January 1 through August 18, firefighters across the United States have responded to 49,242 wildfires burning more than 7.2 million acres — 129% of the 10-year average in number of fires and 168% of average in acres burned. The comparable period in 2025 saw 44,130 fires and 3.77 million acres, making 2026 dramatically worse on both metrics.

Key Fires Currently Burning in the Northwest

The Northwest's active fire list reads like a crisis summary. Among the most significant incidents:

  • Sinlahekin Fire (Okanogan County, WA): The largest active fire in Washington at 152,682 acres, 44% contained, burning 12 miles west of Tonasket.
  • Little Giant Fire (Chelan County, WA): 132,990 acres with only 10% containment, burning 30 miles northwest of Leavenworth and recently rated the highest-priority fire in the nation.
  • Kaiser Canyon Fire (Okanogan County, WA): 138,296 acres, 83% contained, 1 mile south of Nespelem — prompted mass evacuations of the entire community of Nespelem.
  • Big Grass Fire (Malheur County, OR / Owyhee County, ID): A massive 578,422-acre fire at 71% containment, burning along the Oregon-Idaho border south of Jordan Valley.
  • Grasshopper Fire (Grant County, OR): 90,130 acres, 47% contained, burning 3 miles north of Sportsmans Park.
  • Hagen Fire (Umatilla County, OR): 56,419 acres, only 14% contained, 26 miles east of Pendleton.
  • Rowe Creek Complex (Wheeler County, OR): 373,784 acres, 89% contained, 10 miles south of Fossil.

Weather Concerns Persist

The National Weather Service is monitoring warm, dry, and breezy afternoon conditions across the Cascade gaps in eastern Oregon and Washington, with wind gusts of 30–40 mph and relative humidity values dropping into the teens during afternoon and early evening hours. These conditions present elevated fire weather concerns that could drive further growth on existing fires or ignite new starts.

Looking Ahead

Fire officials warn that prepositioning of firefighting resources for initial attack — particularly in areas identified by predictive services as having high fire growth potential — remains a critical balancing act. The Northwest Coordination Center (NWCC) is actively managing resource requests and allocations across the region's many complex incidents.

Residents throughout eastern Oregon, eastern Washington, and northern Idaho are urged to stay informed through local emergency management alerts, InciWeb at inciweb.wildfire.gov, and the NIFC daily fire news report at nifc.gov.
