What a new front looks like on the ground in eastern Washington once the plume has passed over a populated area.

A New Wildfire Front Just Opened in the Pacific Northwest
Every wildfire smoke story I've covered this season has come from the Northeast or the Midwest. This week that changed. A fast growing fire in Eastern Washington gave the Pacific Northwest its first hazardous air event of 2026, and then, in the space of about a day, the air started clearing while the fire itself kept getting bigger. Both things are true at once, and the honest version of this story needs both.
- The Kaiser Canyon Fire near Nespelem, Washington grew from about 80,000 acres to 106,482 acres in 48 hours and remains only 3 percent contained.
- Nine Eastern Washington counties were placed under a hazardous air alert this week as PM2.5 forecast reached unhealthy to very unhealthy levels near the fire.
- Winds shifted Friday morning and started clearing the smoke, even as the fire itself keeps growing, dropping Spokane's air quality index back to a moderate 62.
- It's the first time this wildfire season has produced a hazardous air event in the Pacific Northwest rather than the Northeast or Midwest.
Acres, and growing
Up from roughly 80,000 two days earlier, a jump of about 26,000 acres in 48 hours, at 3 percent contained.
Spokane air quality index
Moderate, after several days in unhealthy to hazardous territory. Strong southwesterly winds cleared the smoke out.
Both numbers are from the same Friday. A fire can keep growing while the smoke it produces is blown somewhere else, at least for a while.
A new front in this year's wildfire season
The Kaiser Canyon Fire is burning near Nespelem, Washington, across the Colville Reservation in Okanogan and Ferry counties. It grew from roughly 80,000 acres on July 23 to 106,482 acres by July 24, a jump of about 26,000 acres in 48 hours, while remaining just 3 percent contained. The Spokane Regional Clean Air Agency and the Washington Department of Ecology issued a multi county air quality alert covering Spokane, Ferry, Lincoln, Okanogan, Grant, Adams, Whitman, Pend Oreille, and Stevens counties, with PM2.5 forecast to reach unhealthy to very unhealthy and hazardous levels near the fire.
Growing fire, clearing air, two different numbers
Both things are true at once, and the honest version of this story needs both.
The clean air agency's own Friday morning forecast, checked directly, says strong southwesterly winds will clear much of the smoke out of Spokane County on Friday and Saturday, dropping the air quality index to a moderate 62 after several days in unhealthy to hazardous territory. That's the exact peak then clear pattern already seen with the New York wildfire smoke event earlier this month. A fire can keep growing while the smoke it produces gets blown somewhere else, at least for a while.
Honest caveat
The hazardous air alert had already lapsed by the time this was checked, and the agency's own forecast shows conditions improving through the weekend, so treating this as an acute, ongoing health emergency right now would overstate the current air quality picture. The fire itself is still large, growing, and barely contained, and forecasters note continued fire spread risk from hot, dry, windy weekend conditions. Conditions could reverse again quickly if winds shift, the way they have repeatedly in the Northeast and Midwest wildfire story this month.
What this means for you
If you're in Eastern Washington or anywhere downwind of an active fire, the acreage number in the headlines isn't the number that tells you whether it's safe to be outside today. Check a live local air quality forecast, not just how big the fire is. And if you're stocking up ahead of the next smoke event, which forecasters say is a real possibility given this weekend's weather, that's worth doing before the next alert hits, not during it.

Common questions
How bad is the Kaiser Canyon Fire right now?
As of Friday, July 24, 2026, the fire near Nespelem, Washington had grown to 106,482 acres, up from roughly 80,000 acres just two days earlier, and remained only 3 percent contained. It's burning across the Colville Reservation in Okanogan and Ferry counties, and forecasters note continued fire spread risk from hot, dry, and windy weekend conditions.
Is the air actually safe to breathe in Eastern Washington right now?
The multi county hazardous air alert that covered Spokane, Ferry, Lincoln, Okanogan, Grant, Adams, Whitman, Pend Oreille, and Stevens counties had lapsed by Friday morning. The Spokane Regional Clean Air Agency's own forecast said strong southwesterly winds would clear much of the smoke out of Spokane County through the weekend, dropping the air quality index back to a moderate 62. Conditions closer to the fire itself, and conditions anywhere if winds shift again, can look very different, so check a live local forecast rather than relying on this alone.
If the fire is getting worse, why is the air getting better?
Fire acreage and local air quality are two different measurements. A fire can keep growing in size while the smoke it produces gets blown somewhere else by shifting winds, which is exactly what happened here and mirrors a pattern already seen with wildfire smoke events in the Northeast and Midwest this year. Checking a fire's size tells you how big the fire is, not whether the air where you live is safe to breathe.
