If you are planning outdoor activities and in a group that is sensitive to the air quality, the Wisconsin Department of Natural Resources has issued an alert that will last until 11 p.m. tonight for Door, Kewaunee, and Manitowoc counties along the Lake Michigan Shoreline. Groups sensitive to it should make outdoor activities shorter in length and less intense. You should also watch for symptoms like coughing and shortness of breath.
