The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for east central and southeastern Minnesota. The alert takes effect Sunday, June 4, beginning at noon, and runs until Monday, June 5, at 9 a.m. The affected area includes east central and southeastern Minnesota, and the tribal nations of Prairie Island and Mille Lacs. Air quality is expected to reach the orange AQI category, which is unhealthy for sensitive groups.
A band of smoke from wildfires in Quebec is currently moving west across the Great Lakes and Wisconsin. Smoke will cross into eastern Minnesota late Sunday morning. The smoke may make it as far west as Rochester and St Cloud. Air quality should improve across east central and southeastern Minnesota tomorrow morning. Some smoke may linger across southeast Minnesota through Monday. In addition, sunny skies, light winds, and warm temperatures will allow pollutants (Volatile Organic Compounds and Oxides of Nitrogen) to react in the air and form high levels of ozone from the Twin Cities to St Cloud.
Fine particle levels are expected to reach the orange air quality index (AQI) category, a level considered unhealthy for sensitive groups, across east central and southeast Minnesota. Ozone may also reach the orange air quality index in the Twin Cities Metro to St Cloud Sunday afternoon. The alert area includes Winona, Rochester, the Twin Cities, Hinckley, St Cloud, and the tribal nations of Prairie Island and Mille Lacs. In the orange area, sensitive groups should avoid prolonged time outdoors.
What this alert means
Air moves long distances and carries pollutants. During air quality alerts due to wildfires, the air is mixed with harmful smoke. Wildfire smoke spreads or lingers depending on the size of the fires, the wind, and the weather.
The air quality index (AQI) is color-coded. Air quality alerts are issued when the AQI is forecast to reach an unhealthy level, which includes forecasts in the orange, red, purple, and maroon categories. For a full description of each air quality category, visit airnow.gov.
Orange air quality: Unhealthy for sensitive groups
Sights and smells: In areas where air quality is in the orange AQI category due to wildfires, the sky may look hazy and residents may smell smoke even when wildfires are far away.
Health effects: This air is unhealthy for sensitive groups and pollution may aggravate heart and lung disease as well as cardiovascular and respiratory conditions. Symptoms may include chest pain, shortness of breath, wheezing, coughing, and fatigue.
What to do: People in sensitive groups are encouraged to reduce outdoor physical activities, take more breaks, or do less intense activities to reduce their exposure. People with asthma should follow their asthma action plan and keep their rescue inhaler nearby.
Who’s most at risk
Poor air quality impacts health. Fine particle pollution from wildfire smoke can irritate eyes, nose, and throat, and cause coughing, chest tightness, shortness of breath, dizziness, or fatigue. Smoke particles are small enough that they can be breathed deeply into lungs and enter the bloodstream. This can lead to illnesses such as bronchitis or aggravate existing chronic heart and lung diseases, triggering heart palpitations, asthma attacks, heart attacks, and strokes.
Certain groups experience health effects from unhealthy air quality sooner than others, either because they are more sensitive to fine particle pollution or because they are exposed to larger amounts of it.
Sensitive groups include:
- People who have asthma or other breathing conditions like chronic obstructive pulmonary disease (COPD).
- People who have heart disease, high blood pressure, or diabetes.
- Pregnant people.
- Children and older adults.
People with increased exposure include:
- People of all ages who do longer or more vigorous physical activity outdoors.
- People who work outdoors, especially workers who do heavy manual labor.
- People who exercise or play sports outdoors, including children.
- People who don’t have air conditioning and need to keep windows open to stay cool.
- People in housing not tight enough to keep unhealthy air out, or who do not have permanent shelter.
Anyone experiencing health effects related to poor air quality should contact their health care provider. Those with severe symptoms, chest pain, trouble breathing, or who fear they may be experiencing a heart attack or stroke should call 911 immediately.
