Washington State Wildfires 2026

Multiple factors combined: extreme heat, low humidity, and fierce winds of 35–40 mph created perfect wildfire conditions across central and eastern Washington in late July and early August. The National Weather Service issued the first-ever 'particularly dangerous situation' Red Flag Warning for the region, an unprecedented alert level, reflecting conditions the state had not seen before. Investigators also determined that the Old Trails Fire, one of the Spokane Complex fires, was set deliberately; an arson arrest was made in connection with it.

Between 700 and 1,100 structures were destroyed in the Spokane area fires alone, according to officials. The bulk of the damage was caused by the Spokane Complex Fires (Old Trails, Autumn Lane, and Fairview fires), which broke out on the afternoon of August 1, 2026. City officials described it as the 'worst natural disaster the region has faced'. Sources: Spokesman-Review, CBS News, NPR.

About 60,000–65,000 people were under evacuation orders or warnings in Spokane County alone, after the Spokane Complex Fires swept through in the afternoon of August 1, 2026. Spokane Mayor Lisa Brown said nearly half the city's neighborhoods were evacuated or at risk. Evacuation orders and warnings were also in effect around Lake Chelan, Tonasket, Inchelium, and Mead for other large fires burning statewide. Sources: CNN, NPR, DSHS Washington.

As of August 18–19, 2026, the state is at National Preparedness Level 5 with 40 active wildfires burning over 569,143 acres statewide. The major fires: Sinlahekin Fire (153,843 acres, 44% contained, Okanogan County, near Tonasket); Little Giant Fire (134,635 acres, 10% contained, Chelan/Okanogan counties, near Lake Chelan, still very active); Modrite Fire (57,665 acres, 83% contained, Ferry/Stevens counties); Ptarmigan Fire (24,516 acres, 40% contained, Okanogan/Pasayten Wilderness); Spokane Complex (Old Trails, Autumn Lane, Fairview fires, 700–1,100 structures destroyed Aug 1, 97% contained as of Aug 14 with command transferred back to state/local units). A Red Flag Warning was in effect Aug 18 for the Lower Palouse and Snake River zone (winds to 25 mph, humidity 12–19%). Sources: DSHS Washington, Fox 13 Seattle, NIFC, firerisk.ai.

Yes. A man was charged with arson in connection with the Old Trails Fire, one of the three Spokane Complex fires that devastated the Airway Heights area north of Spokane on August 1, 2026. The investigation is ongoing. Sources: CNN, Spokesman-Review.

The Spokane Complex refers to three related fires that broke out simultaneously in the afternoon of August 1, 2026, in Spokane County: the Old Trails Fire (north of Airway Heights), the Autumn Lane Fire (near Nine Mile Falls), and the Fairview Fire (near Mead). Driven by 35–40 mph winds, the fires spread rapidly and collectively destroyed between 700 and 1,100 structures, forcing the evacuation of around 60,000 people. As of August 5, both Old Trails and Autumn Lane were 13% contained. Sources: CNN, NPR, CBS News.

Yes. Washington Governor Bob Ferguson declared a state of emergency as fires erupted across the state. The declaration unlocks state resources and can accelerate federal assistance. The National Guard was also mobilized to support evacuation and firefighting operations. Sources: CNN, Washington National Guard, DSHS.

As of August 14–19, 2026, the Spokane Complex fires (Old Trails, Autumn Lane, Fairview) are 97% contained and command has been transferred from the California Incident Management Team 7 back to state and local units. Most Spokane-area evacuation orders tied to these fires have been lifted. However, evacuation orders or warnings remain active in Okanogan and Chelan counties (Tonasket, Inchelium, Lake Chelan area) due to the still-active Sinlahekin and Little Giant fires. Smoke and air quality remain significant health concerns across eastern Washington, AQI near Sinlahekin was rated 'Unhealthy for Sensitive Groups' (AQI 132) on Aug 18. Residents should check current status via Spokane County Emergency Management and AirNow/IQAir. Sources: Fox 13 Seattle, DSHS Washington, IQAir.

The Spokane Complex fires are described as the 'worst natural disaster the Spokane region has faced' and the 700–1,100 structures destroyed in Spokane County in a single afternoon makes August 1, 2026 one of the most destructive wildfire days in Washington state history. Statewide, hundreds of thousands of acres are burning, with some fires still 0–1% contained. The scale puts 2026 among the most severe wildfire years the state has recorded.
