The MPCA said the alert was triggered by incoming smoke from Canadian wildfires, which will make its way to Minnesota via northerly winds.
“Heavy smoke is expected to arrive around 10 p.m. Wednesday near the Canadian border and mid-morning on Thursday in central and southern Minnesota. Smoke will remain over the area into Friday,” the agency reported Wednesday. “During this time, fine particle levels are expected to be in the Orange AQI category, a level that is considered unhealthy for sensitive groups. Fine particle levels will begin to improve Friday morning as southerly winds start moving the smoke out of the state.”READ MORE: Minnesota Weather: Frost Possible In Parts Of The State Overnight
Fine particle levels in northern Minnesota are considered very unhealthy for everyone.
MPCA says the air quality should improve by Friday afternoon.
The agency encourages people who are affected by unhealthy air quality, such as the elderly or those with respiratory or heart conditions, to limit their physical activity and take the proper precautions.MORE NEWS: Minnesota Weather: Severe Weather Threat Ends For Southeastern Minnesota
