Wildfire Smoke from Canada and US Fires Deteriorates Air Quality Across Western North America

Smoke from wildfires burning in British Columbia, Washington, Oregon and other parts of the western United States has spread across a broad region, prompting unhealthy‑air alerts in Washington, Oregon, Idaho, Montana, Colorado, Minnesota and parts of Canada. Heat advisories were also issued for inland Oregon and Washington as temperatures approached 100 °F, compounding health risks.

In British Columbia, the provincial Wildfire Service reported 129 active fires, including 35 that started in the previous 24 hours, while the Kootenay Lake area received a yellow‑level poor‑air warning. In the United States, Washington’s eastern counties were placed under a "Very Unhealthy" alert, and Colorado’s air‑quality index reached 110‑130 in several counties, prompting health advisories. Minnesota’s Pollution Control Agency warned of hazy skies as smoke drifted eastward from the Pacific Northwest.

Community responses include DIY air‑purifier workshops in British Columbia, where participants build filters for under $60 that perform comparably to commercial HEPA units. Health officials across the affected regions advise staying indoors, limiting strenuous activity, and using filtered air, especially for vulnerable groups such as children, the elderly and those with respiratory or heart conditions.
