Montana Faces Air Quality Alert Amid Wildfire Smoke
US · Published Jul 27, 2026
The Montana Department of Environmental Quality (DEQ) has issued an Air Quality Alert for multiple counties, including Choteau, Missoula, and Ravalli, due to elevated particulate levels from wildfire smoke. The alert is in effect until 9:00 AM on Monday, July 27,
Current conditions show air quality levels as 'Unhealthy for Sensitive Groups' in Cut Bank, Hamilton, and Missoula, while other areas like Butte and Helena are experiencing 'Moderate' air quality. Wildfires in Montana, Oregon, and Washington are contributing to the smoke, with the Perkins Fire, Elder 1 Fire, and North Fork Lost Horse Fire seeing significant growth. The Rapid Refresh Forecast System (RRFS) predicts heavy smoke across much of Montana by Monday afternoon. (Source: Montana DEQ, HRRR-smoke, NOAA; Source time: not specified)

Impact & Risks

The wildfire smoke is expected to significantly impact air quality, particularly during the evening and overnight hours when smoke settles closer to the surface. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, are at higher risk of health issues. Communities downwind of active fires, such as those near Anaconda, Frenchtown, and Hamilton, are likely to experience the most severe air quality impacts. The combination of unseasonably warm air, low humidity, and gusty winds may exacerbate fire spread and worsen air quality conditions.
