Smoke across the region is coming from wildfires in Canada and Minnesota. This is resulting in poor air quality across the Upper Great Lakes. Recommendations: avoid strenuous outdoor activities, especially if you have heart disease and respiratory conditions; keep an eye out for symptoms (wheezing, coughing, chest tightness, dizziness, or burning in the nose, throat and eyes); keep windows closed to prevent smoke from getting indoors; if possible run central air conditioning with MERV-13 or higher rated filters.
