Current Issues
Forest Fire Air Quality Updates
447-1644
Due to forest fires in Lewis and Clark County we are seeing short periods of poor air quality in the Helena Valley. These episodes are lasting from one to three hours and change rapidly with wind changes.
If you are concerned about air quality during this forest fire episode , please use the visibility guidelines to determine air quality conditions and adjust your outdoor physical activity accordingly. As a general rule, if you cannot see the North Hills from Helena, the air quality is poor.
Visibility guidelines and other air quality information is also available on the Montana Department of Environmental Quality website.
