Oregon is experiencing one of its most destructive wildfire seasons on record, with more than 1.5 million acres actively burning across 32 large fires as of July 28, 2026. The blazes — concentrated in central and eastern Oregon — are destroying homes, forcing thousands of residents to flee, choking the air with hazardous smoke, and stretching firefighting resources to their limits.

Scale of the Crisis

The National Interagency Fire Center (NIFC) reported 92 large fires burning nationwide on July 28, with Oregon alone accounting for 34 of them — by far the highest concentration of any state in the country. Washington added 13 more large fires, Idaho contributed 3, and Montana had 5, making the Pacific Northwest the unquestioned epicenter of the 2026 fire season.

Nationally, 25,244 firefighters and support personnel are currently engaged, deploying 558 crews, 1,525 engines, and 156 helicopters. So far this year, 42,651 fires have burned more than 4.5 million acres across the United States. Nine new large incidents were added to the national count in a single day on July 28 alone.

Oregon alone has surpassed 1.5 million active acres — a staggering figure driven primarily by lightning-sparked ignitions following mid-July severe thunderstorm events that swept through parched forests and rangelands baked by weeks of above-normal temperatures and critically low humidity.

The Fires Driving the Crisis

Several fires are driving the bulk of Oregon's acreage:

  • Big Grass Fire — Approximately 288,000–300,000 acres along the Oregon-Idaho border near Jordan Valley; only 5% contained as of July 28
  • Bench Fire — 40,296 acres near Warm Springs in Jefferson County, threatening the Confederated Tribes of Warm Springs Reservation; at least 6 homes and 5 other structures destroyed
  • Grasshopper Fire — Over 10,700 acres in Mt. Hood National Forest in Wasco County; FEMA Fire Management Assistance Grant approved
  • Castle Fire — Approximately 1,400 acres on the Umpqua National Forest in steep, rocky terrain near Milo; an Australian/New Zealand Incident Management Team has been assigned

Beyond these headline fires, dozens of smaller but significant blazes continue burning across central and eastern Oregon, collectively consuming vast stretches of high desert rangeland and forested landscape.

Resources at the Breaking Point

The Northwest Geographic Area now has 48 uncontained large fires and 19 Complex Incident Management Teams committed across Oregon and Washington — a level of commitment that has pushed domestic resources to their limits. The strain has prompted NIFC to mobilize 74 fire management specialists from Australia and New Zealand under longstanding bilateral arrangements that have been in effect since 2002.

Conditions Remain Challenging

Weather is providing little relief. Breezy west winds of 10–20 mph with gusts to 30 mph are expected across the Columbia Basin and northeast Washington, with relative humidity dropping to 15–25% in some areas. Fire managers are urging the public to respect all active fire restrictions, avoid outdoor burning, and stay clear of active fire corridors to allow crews to work safely.

Residents in fire-affected areas should monitor local emergency management offices, the Oregon Office of Emergency Management at oregon.gov/oem, and InciWeb at inciweb.nwcg.gov for the latest evacuation orders and fire updates.
