‘It smells like smoke:' Video shows wall of wildfire smoke across Chicago, suburbs

Wildfire smoke from Canada triggered an air quality alert for most of the Chicago area, including northern Illinois and northwest Indiana. The National Weather Service issued the alert until midnight due to smoke and unhealthy ozone pollutants. Consequently, the Illinois Environmental Protection Agency declared an Air Pollution Action Day. Residents were urged to limit prolonged outdoor activity and take frequent breaks. Video footage from Lincoln Park confirmed a visible wall of smoke across the region.
