Green Bay, Wis. – Drivers across Wisconsin faced dense morning fog and wildfire smoke Monday, with reduced visibility and elevated health risks triggering statewide alerts. Air Quality Advisories remain in effect until noon, especially affecting sensitive groups.
According to the Wisconsin Department of Natural Resources and the National Weather Service in Green Bay, Canadian wildfire smoke continues to impact surface air quality across all of Wisconsin. PM2.5 pollution levels are expected to range from “Unhealthy for Sensitive Groups” to “Unhealthy,” particularly in eastern and central counties.
Major impacts are being felt in cities like Green Bay, Wausau, Appleton, and Oshkosh, where haze and low visibility are combining with stagnant winds. Motorists should use caution during the early commute, as visibilities drop below 3 miles in some areas. Those with respiratory or heart conditions should avoid outdoor activity.
