On Monday, June 2, an Air Quality Advisory has been issued by the Michigan Department of Environmental Quality for a large portion of Northern Michigan. This warning is in effect due to elevated levels of fine particulate matter (PM2.5), which are forecasted to reach the “Unhealthy for Sensitive Groups” threshold.
Counties under advisory
The advisory applies specifically to Menominee, Keweenaw, Dickinson, Iron, Marquette, Baraga, Southern Schoolcraft, Northern Houghton, Delta, Ontonagon, Gogebic, Luce, Alger, Northern Schoolcraft, and Southern Houghton counties. These areas are expected to see a significant increase in airborne particles, primarily due to lingering smoke and haze from regional fires or atmospheric stagnation.
Groups at risk and health symptoms
The warning is especially important for individuals with asthma, heart disease, or chronic respiratory conditions. These groups are more susceptible to PM2.5 and may experience wheezing, persistent coughing, chest pressure, dizziness, or irritation in the eyes, nose, or throat.
Indoor precautions and air quality tips
Authorities are recommending keeping windows closed, especially during the overnight hours, to avoid the intrusion of polluted outdoor air. When possible, running central air conditioning systems equipped with MERV-13 or higher-rated filters can help reduce indoor pollutant levels.
To help ease the regional burden of pollution, residents are strongly urged to refrain from outdoor burning and to limit the use of wood-burning appliances during this advisory.
Monitoring air quality levels

For additional health guidance regarding exposure to wildfire smoke and airborne particulates, residents are encouraged to refer to the Michigan Department of Health and Human Services (MDHHS) official resources.
