Canadian wildfire smoke caused unhealthy air quality alerts across several Midwestern states for the third consecutive day. Iowa, Minnesota, Wisconsin, Michigan, and parts of Nebraska, Indiana, and Illinois were affected. Minneapolis experienced some of the world's worst air pollution. The Air Quality Index (AQI) reached unhealthy levels, particularly impacting sensitive groups like children and those with respiratory illnesses. While air quality improved in some areas Saturday, officials warned conditions could remain unhealthy through Monday, potentially spreading as far south as Tennessee and Missouri. Authorities advised reducing outdoor activities and keeping windows closed.
