A shift in weather patterns is bringing temporary relief to the Pacific Northwest this week, with cooler temperatures and recent precipitation helping to moderate fire behavior across Oregon, Washington, and Idaho. However, fire weather forecasters caution that the respite may be short-lived, and critical fire danger persists across portions of the southern United States.

Northwest: Cooler and Wetter

The National Interagency Fire Center's (NIFC) September 7 situation report described "little to no risk of significant fire potential" across the Pacific Northwest, attributing the improved conditions to cooler temperatures and recent rainfall. Firefighters across the region have been taking advantage of the benign weather to make aggressive containment progress on multiple incidents, and no new large fires were reported in the Northwest over the Labor Day holiday weekend.

The weather pattern shift also brought scattered showers over several active fire areas, including the Three Queens and Sisi fires in Washington's Cascades and the Hagen and Paradise fires in northeast Oregon. While the precipitation was not enough to extinguish any of these fires, it helped reduce fire activity and gave crews safer working conditions.

What the September Outlook Says

NIFC's September 1 Predictive Services outlook — the most recent monthly forecast — offers a more nuanced picture of what fire managers can expect through the rest of the month. While the Northwest faces decreased fire potential compared to the record August, the report notes that the season is far from over.

Key takeaways from the September outlook include:

  • The Northwest's overall ignition numbers this year have been below average, but a series of high-impact weather events — including the late-August Red Flag event east of the Cascades — led to explosive fire growth on existing fires
  • National Preparedness Level 5, the highest on the scale, remained in effect throughout August and into September due to sustained resource demand
  • Temperatures and drought conditions in the interior Northwest remain above average, meaning fuels stay dry even after modest rainfall
  • East wind events in October remain a possibility and a concern for fire managers

Earlier Season: A Historic Red Flag Event

The fire weather event that defined the 2026 season in Washington occurred in late August, when a Particularly Dangerous Situation (PDS) Red Flag Warning — the first of its kind ever issued in Washington state history — preceded a catastrophic outbreak of fires near Spokane. Forecasters with the National Weather Service described it as a "particularly dangerous situation" due to the combination of extremely low humidity, high temperatures, and strong gusty east winds coinciding with already-dry fuels across Eastern Washington.

That event resulted in the rapid growth of multiple fires near Spokane, the destruction of more than 840 structures, and the evacuation of approximately 64,000 residents.

Southern Plains Remain Dangerous

While the Northwest catches a break, fire weather forecasters are tracking critical conditions across the southern Plains and southern Mississippi Valley on Tuesday. Temperatures are forecast to reach 100°F in Oklahoma and Arkansas, with relative humidity dropping to 25–30 percent and locally breezy winds. NIFC's weather forecasters described the setup as supporting "moderate to high-risk significant fire potential" across the region.

Texas also reported an active fire, the Alma Fire in Ellis County, with the Texas A&M Forest Service deploying personnel, equipment, and air resources to support local fire departments as of September 4.

Looking Ahead

The key question for Northwest fire managers is whether cooler, wetter conditions will persist long enough to bring current active fires to full containment before the return of drier, windier weather. With 33 large fires still burning across Washington, Idaho, and Oregon, crews are working urgently to close remaining gaps in containment lines while the weather cooperates.
