The ongoing wildfires are significantly affecting air quality across the Pacific Northwest, including the Puget Sound corridor, as smoke from eastern fires spreads westward. The Okanogan highlands, Methow Valley, and Columbia Basin are among the most impacted areas, with large fires also reported in Chelan, Okanogan, and Whatcom counties. Residents in these regions face risks from poor air quality and potential evacuations. The fires also pose a threat to local wildlife and natural habitats, as well as property and infrastructure in the affected areas.
