Active wildfires in Utah continue to drive fluctuating air quality levels across the state, as the Babylon Fire and Cottonwood Fire contribute to smoke concentrations that have reached unhealthy levels for sensitive groups in several counties. Recent reports indicate shifting winds may further impact air quality in local communities.
Babylon Fire Expansion and Impacts
The Babylon Fire, which ignited on June 26, 2026, approximately 25 miles southwest of Monticello, has expanded to cover 87,554 acres. According to InciWeb, the blaze is being driven by low humidity, dry vegetation, and gusty winds. As of July 4, 2026, 730 personnel were assigned to the incident working on suppression and confinement strategies.
While the fire produced less smoke on a recent Friday than in previous days, officials warned that shifting winds could bring heavier smoke into several communities. In Monticello, air quality was expected to potentially drop to unhealthy for sensitive groups as smoke arrived.
Cottonwood Fire Growth
The Cottonwood Fire in the Fishlake National Forest remains a significant concern. According to InciWeb reports from late June 2026, the fire had grown to approximately 93,607 acres by June 28, 2026. The incident began on June 22, 2026, and experienced rapid growth due to incredibly dry fuels.
Firefighters have been engaged in direct extinguishment tactics near Highway 153 to push toward Lion Flat. The cause of the Cottonwood Fire remains under investigation.
Statewide Air Quality Forecasts
Air quality forecasts from the Utah Department of Environmental Quality indicated unhealthy levels for sensitive groups across several northern and central counties during late June 2026. Specifically, Salt Lake, Davis, Utah, Weber, Box Elder, and Tooele counties were all forecasted to experience unhealthy air quality due to wildfire smoke.
In these areas, the Division of Air Quality issued advisories for employers to activate mandatory trip reduction programs. The agency also advised individuals with existing heart or respiratory ailments to reduce physical exertion and outdoor activity if smoke becomes thick.
Public Land Closures
The impact of wildfire smoke extends to the Manti-La Sal National Forest and Canyonlands National Park. Due to active firefighting operations from the Babylon Fire, extensive public land closures were implemented in the Monticello Ranger District.
The Bureau of Land Management also closed all managed lands west of Harts Draw Road, including areas such as Shay Mesa, Beef Basin, Dark Canyon, and Sweet Alice. Officials advised the public to avoid these areas to ensure the safety of emergency crews.
Ongoing Fire Activity
In addition to large-scale wildfires, other fire activity has been noted in the state. The Utah Wildfire Dashboard reported 6 fires involving 1,115 acres within a recent 24-hour period, including the ongoing Wild Horse fire which was discovered on May 13, 2026.
Historically, officials from the Utah Division of Forestry, Fire and State Lands have noted that warmer weather can lead to escaped debris burns and field clearing fires, requiring significant state response.
Public Health Recommendations
As smoke-related air quality issues persist, the Utah Division of Air Quality continues to monitor particulate matter levels. Residents in affected counties are encouraged to follow TravelWise recommendations by consolidating trips and choosing cleaner transportation options to mitigate further pollution.
