If you noticed a haze over the area Wednesday, the state Pollution Control Agency says you can blame wildfires burning in Canada.
The PCA said it tracked the haze via satellite imagery to Canadian fires. The air-quality index for fine particulate matter in the smoke Wednesday afternoon hit 68 in Duluth and 78 in Virginia. Index readings below 100 generally are considered safe but over 100 are considered unhealthy for sensitive groups such as children, seniors and people with lung ailments.
The PCA recommends that persons in areas where the smell of smoke or visible haze is present take precautions to reduce exposure. When smoke is present, individuals are encouraged to remain indoors and reduce activity levels.
Fortunately, winds were expected to shift today and blow the smoke back north.
