Wildfires continue to devastate eastern Washington state, forcing the evacuation of approximately 5,000 homes and destroying around 600 residential and commercial properties, authorities reported.
The blazes, which remain uncontained, have scorched more than 8 square miles around Spokane, Washington's second-largest city, and are among dozens stretching emergency resources across the western U.S.
No fatalities have been reported in the Spokane area.
The situation in Spokane is particularly challenging due to adverse weather and terrain.
Benjamin Cossel, public information officer for a federal response team deployed from California, noted, "We have weather working against us, and we have terrain working against us."
Wind gusts of 35 to 45 mph were anticipated, exacerbating the spread of the Old Trails, Fairview, and Meadowview Fires.
Washington Gov. Bob Ferguson declared a state of emergency, and the National Weather Service issued a "particularly dangerous situation" red flag alert for eastern Washington.
Cossel explained that the Spokane River, which bisects the city of 229,000, is flanked by steep canyons that funnel winds.
As temperatures rise, cooler air near the ground ascends, allowing these powerful winds to sweep through the area.
"They push the fire through the canyons, up, up the slopes, and then outside the slopes and around," he said, describing the "turbulent, really challenging sort of wind scenarios" created by the hilly and steep landscape.
Meanwhile, a massive wildfire in western Idaho and eastern Oregon has been burning for 10 days, consuming nearly 525 square miles of grassland. This blaze, which authorities attribute to lightning, threatens over 600 homes and 800 other structures in an area vital for cattle ranching.
The regional weather forecast offers little relief, with sunny and dry conditions expected to persist well into the week. Temperatures are projected to climb above 90 degrees Fahrenheit by Wednesday.
The National Weather Service has issued air quality warnings for eastern Washington, eastern Oregon, western and central Idaho, and western Montana. Red flag fire warnings are in effect for parts of Utah, Montana, and western Nebraska, alongside extreme heat warnings for southern Arizona, California, Nevada, and northern Montana.
In Spokane, authorities have established a shelter at the city's main convention center for displaced residents. Keila Vizcarra, spokesperson for the federal team managing the "Big Grass Fire" in Idaho and Oregon, underscored the widespread impact, stating, "The whole northwest is heavily impacted right now."
