Air quality alert issued due to wildfire smoke for Monday and Tuesday for northwestern and west central Minn.
Air quality is expected to reach the orange AQI category across northwestern and far west central Minn., which is unhealthy for sensitive groups
The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for northwestern and far west central Minnesota due to wildfire smoke. The alert is effective through 10 p.m. Tuesday, July 18. The affected area includes East Grand Forks, Moorhead, Roseau, Thief River Falls, Bemidji, Crookston, Detroit Lakes, Fergus Falls, and Ortonville as well as the tribal nations of Leech Lake and Red Lake.
Smoke from wildfires in Quebec has cycled around a very large low-pressure system near Hudson Bay and has looped around into northwestern Minn. Smoke will continue to move south along the Red River Valley and will linger across northwestern and west central Minn. through Tuesday night. The smoke will be slow to dissipate, and the alert may need to be locally extended depending on how fast the smoke dissipates on Tuesday.
Fine particle levels are expected to reach the orange air quality index (AQI) category, a level considered unhealthy for sensitive groups, across northwestern and far west central Minn. 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.
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.
