Air quality alert issued due to wildfire smoke for the entire state of Minnesota until 6 a.m. Friday, May 10
Air quality is expected to reach the red AQI category across all but far northeastern and southeastern Minnesota, which is unhealthy for everyone.
The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for the entire state of Minnesota. The alert runs until Friday, May 19, at 6 a.m.
A band of very heavy ground-level smoke from wildfires in northern Alberta and Saskatchewan is currently moving along a cold front in northwestern Minnesota. The smoke will continue to move south and east and eventually impact the entire state of Minnesota. The smoke should clear rapidly overnight into Friday morning.
Fine particle levels are expected to reach the red air quality index (AQI) category, a level considered unhealthy for everyone, across all but far eastern Minnesota. This area includes The Twin Cities Metropolitan Area, St. Cloud, Mankato, Moorhead, East Grand Forks, Roseau, Bemidji, Alexandria, Marshall, Ortonville, Worthington and the tribal nations of Red Lake and Mille Lacs. In the red area, everyone should avoid prolonged time outdoors.
Fine particle levels are expected to reach the orange AQI category, a level considered unhealthy for sensitive groups, across southeastern, northeastern, and far east central Minnesota. This area includes Rochester, Duluth, Ely, International Falls, Two Harbors, and the tribal nations of Fond du Lac and Grand Portage. 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.
Red air quality: Unhealthy
Sights and smells: In areas where air quality is in the red AQI category due to wildfires, the sky may look smoky. The air will look hazy and you won?t be able to see long distances. You may smell smoke.
Health effects: This air is unhealthy for everyone. Anyone may begin to experience symptoms such as irritated eyes, nose, and throat, coughing, chest tightness, or shortness of breath. Sensitive or more exposed individuals may experience more serious health effects, including worsening of existing heart or lung disease and respiratory and cardiovascular conditions, possibly leading to an asthma attack, heart attack, or stroke.
What to do: Reduce outdoor physical activities, take more breaks, and avoid intense activities to reduce? exposure. Sensitive and more exposed individuals should avoid prolonged or vigorous activities and consider shortening, rescheduling, or moving outdoor events inside.
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.
