Grand Junction, Colo. – Wildfire smoke from multiple active blazes is blanketing parts of western Colorado Wednesday morning, triggering an air quality advisory that will remain in effect until 9 a.m. Thursday.
According to the Colorado Department of Public Health and Environment, smoke concentrations are expected to reach unhealthy levels at times in Mesa, Garfield, Eagle, Pitkin, Delta, Gunnison, Montrose, San Miguel, Ouray, Lake, and Chaffee counties. Affected cities include Grand Junction, Glenwood Springs, Vail, Aspen, Leadville, Delta, Gunnison, Telluride, Montrose, and Salida.
The worst air quality is expected near the South Rim Fire in eastern Montrose County, the Sowbelly and Turner Gulch fires in southern Mesa County, and downwind of the Deer Creek Fire impacting Montrose and San Miguel Counties. Thunderstorm activity may intensify smoke dispersal unpredictably due to shifting winds.
Residents in affected areas should stay indoors if smoke becomes thick, particularly those with heart or lung conditions, older adults, young children, and pregnant individuals. Visibility under 5 miles means smoke has reached levels that are unhealthy for everyone. Use indoor air filters, keep windows closed, and limit strenuous activity outdoors.
The advisory may be extended if smoke levels remain elevated beyond Thursday morning.
