Air quality alert issued due to wildfire smoke for Tuesday, Aug. 15, through Wednesday, Aug. 16, for northern Minnesota
Air quality is expected to reach the red AQI category in northwest Minnesota, which is unhealthy for everyone
The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for northern Minnesota. The alert takes effect at noon on Tuesday, Aug. 15, and runs until 10 a.m. on Wednesday, Aug. 16. The affected area includes Bemidji, East Grand Forks, International Falls, Hibbing, Ely, Roseau, and the tribal nations of Red Lake and Leech Lake.
Heavy ground-level smoke from wildfires in the Northwest Territories of Canada is moving quickly across southern Manitoba and towards the Minnesota border. The smoke is expected to reach northwest Minnesota around noon on Tuesday. The smoke could reach as far south as Bemidji and as far east as Ely. The heaviest smoke will be across the northwest corner of the state. Winds across the region will become southerly by Wednesday morning and the smoke will quickly retreat and clear Minnesota by 10 a.m. Another wave of smoke is expected to move into northwest Minnesota by late Wednesday evening.
Fine particle levels are expected to reach the red air quality index (AQI) category, a level considered unhealthy for everyone, across northwest Minnesota. This area includes East Grand Forks, International Falls, Roseau, and the tribal nation of Red Lake. In the red area, sensitive groups should avoid prolonged or heavy exertion and limit time spent outdoors. Everyone should limit prolonged or heavy exertion and time spent outdoors. Fine particle levels are expected to reach the orange air quality index (AQI) category, a level considered unhealthy for sensitive groups, across northern Minnesota. This area includes Bemidji, Hibbing, Ely, and the tribal nation of Leech Lake. In the orange area, sensitive groups should limit prolonged or heavy exertion and time spent 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.

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.
Take precautions
Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Reduce vehicle trips and vehicle idling as much as possible. Keep windows closed to ensure outside smoke does not enter you home.
