ST. PAUL, MN – A statewide air quality alert is in effect for Minnesota, beginning at 9 a.m. Sunday, June 9th, and lasting untill 9 a.m. Tuesday, June 11th.The Minnesota Pollution Control Agency (MPCA) issued the warning due to significant smoke drifting from wildfires burning in central Saskatchewan and Manitoba, Canada.

The smoke is being carried southward by a low-pressure system. Air quality deterioration began Sunday morning in western minnesota and is expected to spread eastward throughout the day and into Monday. The MPCA anticipates the most severe impacts will be felt in northern and central Minnesota.

residents in areas north of a line extending from Ortonville to St. Cloud are facing “unhealthy for everyone” air quality conditions. those in sensitive groups – including individuals with asthma, chronic obstructive pulmonary disease (COPD), heart disease, and the very young and elderly – south of that line, including the Twin Cities metropolitan area, should also take precautions.

Health officials strongly advise limiting prolonged outdoor exertion, particularly for those with pre-existing cardiovascular or respiratory issues. Individuals experiencing symptoms such as coughing, shortness of breath, or chest pain should consult a medical professional. The MPCA recommends checking the Air Quality Index webpage for the latest updates and conditions in specific locations.

This event highlights the increasing frequency of long-range smoke transport events due to climate change and larger, more intense wildfires. The MPCA is working with state and local partners to monitor the situation and provide timely facts to the public.

Understanding Wildfire Smoke and Air Quality

Wildfire smoke contains a complex mixture of pollutants, including particulate matter (PM2.5), carbon monoxide, nitrogen oxides, and volatile organic compounds. PM2.5,tiny particles less than 2.5 micrometers in diameter, are particularly hazardous as they can penetrate deep into the lungs and bloodstream, causing respiratory and cardiovascular problems. Long-term exposure to wildfire smoke has been linked to increased rates of asthma, heart attacks, and even premature death.

The frequency and intensity of wildfires have been increasing globally, largely due to climate change-related factors such as prolonged droughts, higher temperatures, and increased fuel loads. This trend is expected to continue, leading to more frequent and severe smoke events. Minnesota has experienced several significant smoke episodes in recent years, including those originating from wildfires in western Canada and the United States.

The Air Quality Index (AQI) is a tool used to communicate air quality information to the public. it categorizes air quality into six levels: Good, Moderate, Unhealthy for Sensitive Groups, Unhealthy, Very Unhealthy, and Hazardous. The MPCA provides real-time AQI data and forecasts on its website.
