Wildfire Smoke Triggers Widespread Midwest Air Alerts

Wildfire smoke from both Canada and the western U.S. has caused widespread air quality alerts across Illinois, Wisconsin, Michigan, and Indiana, with some areas reaching 'Very Unhealthy' levels. Environmental agencies in these states have advised all residents, particularly sensitive groups, to limit outdoor activities and keep windows and doors closed. The air quality situation is expected to persist into the weekend as smoke continues to move south. Authorities recommend using resources like the AirNow map and state-specific apps for real-time updates and checking on vulnerable individuals. Although air quality is poor, weather conditions in the Midwest remain mild with cooler temperatures and sunshine. These alerts underscore the persistent impact of North American wildfires on public health in the region.
