The Pacific Northwest has cemented its status as the most active wildfire region in the United States, with 34 uncontained large fires burning across Oregon, Washington, and Idaho as of August 19, 2026. The National Interagency Fire Center (NIFC) reports that the region leads the nation in active incidents, with Oregon alone accounting for 21 large fires, Washington 12, and Idaho 5.

National Fire Situation

Nationwide, firefighters are battling 75 large fires across 17 states, with 26,890 personnel assigned to incidents. August 19 marked the 33rd consecutive day at National Preparedness Level 5 — the highest level — reflecting the sustained and extreme demand on fire resources across the country.

Year-to-date statistics paint a stark picture of 2026's severity. From January 1 through August 19, firefighters have responded to 49,418 wildfires that have burned more than 7.4 million acres — 129% of the 10-year average for number of fires and a staggering 171% of the average for acres burned. By comparison, the same period in 2025 saw 44,470 fires burn just under 4 million acres.

Northwest Fires Drive National Demand

The sheer concentration of large, active fires in the Pacific Northwest is stretching the national firefighting system to its limits. On August 19 alone, 97 new fires were reported nationwide, including seven new large fires. Seven fires were contained over the same period.

"Prepositioning firefighters and firefighting resources strategically for initial attack, especially in areas where predictive services have identified a potential for large fire growth, is a critical consideration during the busiest part of the fire year," NIFC noted in its daily briefing.

Active fires currently burning across the broader Northwest include ongoing major incidents such as the Big Grass Fire on the Oregon-Idaho border, the Sinlahekin Fire in Okanogan County, Washington, the Little Giant Fire in Chelan County, and the Kaiser Canyon Fire on the Colville Reservation.

Historical Context

Active fires in the region are burning across a combined total of more than 3.6 million acres nationally. The 2026 fire year is on pace to be one of the most destructive in modern U.S. history, with fire behavior experts citing a confluence of record heat, prolonged drought, and critically low relative humidity as key drivers.

Communities across eastern Oregon, eastern Washington, and southwestern Idaho have faced evacuation orders, road closures, and ongoing structure threats. Emergency managers are urging residents in or near fire-prone areas to maintain ready-to-go bags, monitor emergency alerts, and have a household evacuation plan in place.

What to Watch

  • Oregon: 21 large fires, including the historic Big Grass and active Grasshopper, Hagen, and Rowe Creek Complex fires
  • Washington: 12 large fires including the Little Giant (only 10% contained) and Sinlahekin fires
  • Idaho: 5 large fires, including portions of the Big Grass and Wrights Spring fires
  • Montana: 9 large fires adding to regional smoke and resource demand

Residents across the Pacific Northwest are urged to stay informed through local emergency management agencies, monitor AirNow for air quality conditions, and follow all evacuation orders without delay.
