Wildfire Smoke Prompts Health Advisories in Colorado and Idaho

The Colorado Department of Public Health and Environment issued an air‑quality health advisory covering more than a dozen counties after five major wildfires – the Willow, Gold Mountain, Aspen Acres, Ferris and Snyder fires – generated dense smoke on the state’s western slope. The advisory warned that the Air Quality Index was above 100 in towns such as Silverthorne, Edwards, Avon and Basalt, and reached 196 in Leadville, indicating conditions unhealthy for sensitive groups and, at higher levels, for the general public. Residents were urged to stay indoors, limit physical activity and use air‑purifying filters, especially those with heart or respiratory conditions, children, older adults and pregnant women.

The Idaho Department of Health and Welfare echoed the warnings, noting that smoke can travel hundreds of miles from wildfire sources and affect air quality across the state. It advised checking the local AQI, reducing outdoor exertion, keeping windows closed, using recirculating HVAC settings, and, for prolonged outdoor exposure, wearing properly fitted N95 respirators. Both states emphasized staying hydrated and monitoring symptoms such as coughing, eye irritation or shortness of breath, and seeking medical care if severe respiratory issues develop.
