'Keep Windows Closed Tonight': Wildfire Smoke Alert Issued For MN

TWIN CITIES, MN — Yes, Canadian wildfire smoke is back. "Keep windows closed tonight," the Minnesota Pollution Control Agency said Sunday.

An air quality alert for "red/unhealthy for all" will be in effect for much of Minnesota — including the Twin Cities metro area — starting Monday at 8 a.m.

Health officials warned that fine particle levels are expected to reach the red air quality index (AQI) category, a level considered unhealthy for everyone.

"A band of very heavy smoke from wildfires in northeast British Columbia has moved into northern Minnesota and will sweep south across the state on Sunday behind a cold front," the PCA said.

"Smoke will persist through midday Monday across southern Minnesota and air quality will gradually improve through the day as the smoke begins to disperse....Everyone should limit prolonged or heavy exertion and time spent outdoors," the PCA added.

Red air quality: Unhealthy for everyone

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.
