High amounts of ground-level ozone on Wednesday is the main reason for the most recent Air Quality Alert that will affect the lakeshore counties of Wisconsin, including Door and Kewaunee Counties, until 11pm.
The highest concentrations of ozone are expected to be contained within the lake breeze, where mostly Unhealthy for Sensitive Groups AQI is anticipated. However, Unhealthy AQI remains a possibility along the shoreline. The Air Quality Alerts have been common this summer, with the Canadian wildfires bearing down and causing most of the air quality concerns. The fires continue to burn at a high level, as according to the Canadian Interagency Forest Fire Centre, there are 1,085 active fires, and 13 million acres of land have been burned due to the fires.
