Wildfires in Washington and Oregon, evacuations and closures in the US federal report

The 07:30 report of Thursday, September 3, 2026 from the National Interagency Fire Center — the Incident Management Situation Report, the operational document with which US federal coordination photographs ongoing wildfires every morning — lists several open situations in the country’s northwest. It is a primary, institutional source, but it is a single origin: no independent confirmation available in the excerpts at our disposal.

Washington: the Sisi front

The Sisi fire is burning within the Okanogan-Wenatchee National Forest, about sixteen kilometers northwest of Stehekin, in the State of Washington. The report flags threatened energy infrastructure: this is the notation that, in the bookkeeping of these documents, distinguishes a forest fire from an incident with knock-on effects on services. On fire behavior the indication is moderate intensity, and precipitation had fallen over the area the previous day.

These are two elements to be read together and with caution: rain reduces the front’s activity on the day it falls, it does not extinguish it, and the report does not contain — in the available excerpts — either the area burned or the containment percentage, the two figures normally used to measure a fire’s progress.

Oregon: Paradise and Hagen

In the Umatilla National Forest, in Oregon, the Paradise and Hagen fires are active: the first east of Milton-Freewater, the second east of Pendleton. On the Paradise front, a change of command from the CIMT SA Team 3 team to the NW Team 8 team was scheduled for September 3. The document does not explain the reasons for the handover.

On multiple incidents the report records evacuations and closures of areas, roads and trails. Here too, in the excerpt, the detail is missing: which communities are involved, how many people have been made to leave, which routes have been cut off. This is a gap we flag because it changes the scale of the fact: an evacuation can involve a few isolated homes or an entire town, and the operational document does not say which.

The same day, elsewhere

September 3 was marked by natural events across several continents. Monitoring bulletins recorded the simultaneous presence of three hurricanes in the Pacific; in the northern United States, violent storms hit North Dakota and Michigan with gusts up to 70 miles per hour. On the seismic front, the same day saw a magnitude 5.4 tremor in China and a magnitude 4.3 one in Colombia, in addition to lower-intensity movements in Puerto Rico and Chile. This second set of information comes from a single source (The World Now, an editorial roundup on seismic and weather bulletins); no independent confirmation available.

What we do not know

We do not have the names or the trajectory of the three hurricanes, nor do we know whether they made landfall or whether alerts were issued for coastal populations. We do not know the precise location of the two larger tremors or any resulting toll of damage or injuries: a magnitude, on its own, says nothing about depth, distance from population centers and consequences. We do not know whether the gusts recorded in North Dakota and Michigan caused power outages.

What the federal report delivers with certainty is a list of open incidents in two national forests, with assigned management teams, ongoing evacuations and exposed energy grids: the wildfire season in the US northwest, as of September 3, was not over.
