Despite some relief from early fall rains in parts of the Pacific Northwest, fire weather concerns have not fully dissipated as September draws to a close. Forecasters are monitoring continued dry conditions across eastern Oregon, eastern Washington, and Idaho — areas that have borne the brunt of the 2026 fire season.

Current Conditions

The National Interagency Coordination Center's September 28 situation report notes that dry conditions are expected to persist for California, the western Great Basin, the Northwest, and northern Rockies. U.S. Drought Monitor data continues to show large portions of eastern Oregon, central Washington, and southern Idaho in severe to exceptional drought conditions — the result of a below-normal precipitation year combined with record summer heat.

Relative humidity in interior valleys of eastern Washington and Oregon has been recovering more slowly than normal, and the region's soil moisture deficit remains significant. This means even modest wind events can quickly elevate fire danger for any remaining active fires or new ignitions.

The August Red Flag Events

The 2026 season's most destructive period came during a late-July through early-August weather pattern that brought a series of Particularly Dangerous Situation (PDS) Red Flag Warnings to eastern Washington and northeastern Oregon — the first such designation for the Pacific Northwest since September 2020. Dry cold fronts generated wind gusts of 40 to 50 mph, driving explosive growth on existing fires and sparking multiple new starts near Spokane.

The Spokane-area fires together damaged or destroyed more than 800 structures within the city, forcing more than 65,000 residents into emergency evacuation — one of the largest urban wildfire evacuations in Pacific Northwest history. The event underscored how wildfire risk is no longer limited to remote forestland; suburban and urban interface areas are now on the front line.

October Fire Risk

October historically brings increased precipitation and reduced temperatures to the Pacific Northwest, but forecasters warn the transition can be uneven. The NIFC monthly outlook, issued September 1, flagged continued elevated fire potential for portions of the Northwest through at least mid-October, particularly if drought-fueled offshore wind events occur before sufficient rain saturates fuels.

Key fire weather indicators to watch:

  • Wind events: Offshore (east-to-west) wind events remain possible into October and can bring rapid humidity drops even as storms approach from the Pacific.
  • Precipitation timing: A single rain event does not end fire season; sustained precipitation over multiple days is needed to significantly reduce fire danger.
  • Fuel moisture: Live and dead fuel moisture levels in many parts of eastern Oregon and Washington remain well below normal for late September.

What Residents Should Do

Until fire season is formally declared over, residents in eastern Oregon, eastern Washington, and Idaho should:

  • Continue avoiding any outdoor burning unless explicitly permitted by local jurisdictions
  • Maintain defensible space around homes and outbuildings
  • Keep emergency go-bags and evacuation plans current
  • Monitor Watch Duty, local emergency management alerts, and fire information websites
