Montana DEQ Issues Air Quality Alert Amid Wildfire Smoke
The Montana Department of Environmental Quality (DEQ) has issued an air quality alert for multiple counties across central and western Montana due to smoke from local and regional wildfires. Active fires in the Pioneer and Sapphire Mountains, including the Bobcat Lakes Fire (8,500 acres) and Sand Creek Fire (19,000 acres), are contributing to unhealthy air conditions. Additionally, massive wildfires in Oregon and Washington are sending smoke into Montana. As of 8 AM on August 11, 2026, particulate levels in Missoula are classified as 'Unhealthy,' while Dillon, Frenchtown, Great Falls, and Hamilton are 'Unhealthy for Sensitive Groups.' Moderate levels are reported in other areas such as Billings and Helena. Relief is expected by Wednesday afternoon as cooler air and precipitation move into the region.
