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 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.
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.
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.
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.
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.
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.
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.
