Air Quality Alert Message Wisconsin Department of Natural Resources Madison WI relayed by National Weather Service Milwaukee/Sullivan WI 1137 AM CDT Mon Aug 4 2025 The Wisconsin Department of Natural Resources has issued an Air Quality Advisory for the following counties: Columbia, Dane, Dodge, Fond du Lac, Green, Green Lake, Iowa, Jefferson, Kenosha, Lafayette, Marquette, Milwaukee, Ozaukee, Racine, Rock, Sauk, Sheboygan, Walworth, Washington, and Waukesha. WHAT...The PM2.5 AQI is expected to reach the Unhealthy for Sensitive Groups to Unhealthy level. WHERE...All of Wisconsin WHEN...Until noon Tuesday, August 5 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: Canadian wildfire smoke will continue to impact surface air quality in Wisconsin. Though significant improvements have been observed over neighboring states yesterday into this morning, a mix of Unhealthy for Sensitive Groups (USG; Orange) AQI and Unhealthy (Red) AQI is forecast again today as smoke persists over Wisconsin and continues to recirculate. The heaviest smoke is expected across northeastern Wisconsin today, while lighter impacts are more likely for southwestern counties. A few locations may observe Moderate (Yellow) AQI, especially to the southwest as a cleaner pocket of air is anticipated to move into the state from the south. Conditions will continue to be reevaluated on a day-to-day basis, including updates to the forecast and any associated Air Quality Advisories.
