Issued: 8:48 PM Jul. 23, 2025 – National Weather Service
The Wisconsin Department of Natural Resources has issued an Air Quality Advisory for the following counties: Ashland, Barron, Bayfield, Burnett, Chippewa, Douglas, Dunn, Iron, Pepin, Pierce, Polk, Price, Rusk, Sawyer, St. Croix, Vilas, Washburn. WHAT...The PM2.5 AQI is expected to reach the Unhealthy for Sensitive Groups (USG) to Unhealthy level. WHERE...Northwest Wisconsin. WHEN...Beginning at 6 AM Thursday morning. 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 move into northwest Wisconsin Thursday morning, likely reaching the Duluth/Superior area between 6 and 9 AM. The smoke will then slowly move southeast throughout the day on Thursday, approximately reaching an Eau Claire-to-Rhinelander line by midnight Thursday night. The Wisconsin DNR will update the advisory area on Thursday afternoon to reflect the newest models and observations. Currently, the smoke is expected to continue moving east and south, impacting much of northern Wisconsin on Friday, with the potential to move travel down Green Bay and Lake Michigan into southern Wisconsin. Southerly winds are expected to begin pushing the smoke back north on Saturday, but lingering smoke impacts could mean an advisory will be necessary for at least some part of Wisconsin over the weekend.
