Smoke from Canadian wildfires is once again moving into Minnesota, causing relatively unhealthy air quality levels.
With that, the Minnesota Pollution Control Agency has issued an air quality alert for parts of southwest, central and northeast Minnesota until 9 a.m. Tuesday.
"A narrow but thick band of wildfire smoke originating from British Columbia is currently over central and northeast Minnesota this morning," the National Weather Service says. "Air pollution monitors show fine particulates greater than an Air Quality Index (AQI) value of 101 (Orange) in this area. This plume of smoke is expected to move south Tuesday and persist into the overnight. During this time, fine particle pollution is expected to remain at, or above, a level that is considered unhealthy for sensitive groups."
Smoke will clear out overnight from north to south, and should be completely gone by 9 a.m. Tuesday.
The air quality is considered unhealthy for sensitive groups, including people with lung disease, asthma, heart disease, along with children, older adults and people working or playing outside for extended periods of time.
