  • August 11 2026

Current Conditions

Montana Department of Environmental Quality has issued an air quality alert for Beaverhead, Deer Lodge, Flathead, Gallatin, Granite, Jefferson, Lake, Lewis and Clark, Lincoln, Madison, Mineral, Missoula, Park, Powell, Ravalli, Sanders, Silver Bow counties in effect until 9AM on 08/12/2026.

An Air Resource Advisor has been assigned to the smoke event across central and western Montana due to local and regional wildfires.

Monday afternoon, the most active Montana wildfires continued burning in the Pioneer and Sapphire Mountains. The Bobcat Lakes Fire has burned more than 8,500 acres. The Sand Creek Fire has grown quickly over the last 48-hours, burning over 19,000 acres. It is now burning atop Maverick Mountain with evacuation orders for Elkhorn Hot Springs and the Maverick Mountain area. These fires will continue sending smoke to communities downstream like Whitehall and Bozeman on Tuesday. The Moose and Black Bear fires, burning in the Sapphire Mountains between Georgetown Lake and the Bitterroot Valley, exhibited active fire behavior again on Monday. The Moose Fire has burned over 5,000 acres. The Black Bear Fire has burned more than 1,900 acres. These fires will send smoke to communities like Helena. Despite numerous active wildfires burning in the state, the bulk of the surface smoke over Montana is the result of massive wildfires burning in Oregon and Washington.

As of 8 AM, particulate levels in Missoula are Unhealthy. Particulate levels in Dillon, Frenchtown, Great Falls and Hamilton are Unhealthy for Sensitive Groups. Particulate levels in Billings, Butte, Choteau, Columbia Falls, Cut Bank, Helena, Lewistown, Libby, Malta, Thompson Falls and West Yellowstone are Moderate.

By Wednesday afternoon, the Rapid Refresh Forecast System (RRFS) smoke model shows less surface smoke over western Montana thanks to an approaching area of low pressure and cooler air.

Forecast

Montanans can expect one more hot day with active fire weather on Tuesday. Hot, dry, and windy conditions will bring elevated fire weather to the region. This will lead to rapid fire spread on established and emerging wildfires. Afternoon wind gusts will reach 30-40 miles per hour. Better mixing could bring improving air quality to some Montana airsheds by Tuesday afternoon and evening.

An area of low pressure pushes into the state on Wednesday. At the same time, monsoonal moisture will surge north into Montana. Clouds, cooler temperatures, and scattered precipitation will help to ease fire behavior and reduce smoke production. Expect better air quality across the region starting Wednesday. A cold front will move across the state Wednesday night and early Thursday. This should further help provide relief from dense surface smoke.

The best window for widespread beneficial rainfall for the region is between Wednesday night and Thursday. A southwesterly flow returns to Montana between Friday and the weekend. This should bring daily chances for showers and thunderstorms. Despite the precipitation, this is unlikely to be the season ending event many of us hoped for. Stay tuned!

Conditions can change quickly as weather could stimulate active fires and the likelihood of new starts increases. Please keep track of concentrations at todaysair.mtdeq.us or the Fire and Smoke Map.

Smoke remains visible across much of the state early Tuesday from regional wildfires.
