Air Quality Alert
Issued: 3:29 PM Jul. 17, 2026 – National Weather Service
The Wisconsin Department of Natural Resources has issued an Air Quality Advisory for the following counties: Ashland, Bayfield, Brown, Calumet, Dodge, Door, Douglas, Florence, Fond du Lac, Forest, Iron, Jefferson, Kenosha, Kewaunee, Langlade, Manitowoc, Marinette, Menominee, Milwaukee, Oconto, Outagamie, Ozaukee, Racine, Rock, Shawano, Sheboygan, Walworth, Washington, Waukesha, Waupaca, Winnebago. WHAT...The PM2.5 AQI is expected to reach the Unhealthy for Sensitive Groups (Orange) to Unhealthy (Red) level. WHERE...Eastern Wisconsin and near-shore areas of Lake Superior. WHEN...From noon until 6 p.m. Precautionary/Preparedness Actions: Sensitive groups: Consider rescheduling or moving all activities inside. Go inside if you have symptoms. People with asthma: Follow your asthma action plan and keep quick-relief medicine handy. People with heart disease: Symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider. Everyone else: Keep outdoor activities shorter and less intense. Go inside if you have symptoms. Additional Details: A statewide Air Quality Advisory will remain in effect until noon today. Clearing of the smoke is expected from west to east, but eastern areas will continue to see impacts beyond noon, which this advisory addresses. It remains unclear how Lake Superior will impact the clearing of smoke for near shore communities. Out of an abundance of caution, this advisory covers counties adjacent to Lake Superior, although only near shore portions of these counties may continue to see smoke impacts. It remains possible that near shore areas will clear out more quickly than this advisory suggests. For more information on current air quality, please see: https://airquality.wi.gov
