Non-Weather Emergency Message. Not sent to IPAWS.

Effective: Thu June 4, 2026, 11:39 AM
Expires: Thu June 4, 2026, 11:00 PM

The Wisconsin Department of Natural Resources has issued an Air Quality Advisory for the following counties: Dodge, Fond du Lac, Jefferson, Kenosha, Milwaukee, Ozaukee, Racine, Rock, Sheboygan, Walworth, Washington, and Waukesha. WHAT...The Ozone AQI is expected to reach the Unhealthy for Sensitive Groups (Orange) level. WHERE...Southeast and east-central Wisconsin. WHEN...From noon until 11 p.m. today. Precautionary/Preparedness Actions: Sensitive groups: Do not do long or intense outdoor activities. Schedule outdoor activities in the morning when ozone is lower. Consider moving activities indoors. People with asthma: Follow your asthma action plan and keep quick- relief medicine handy. Everyone else: Reduce long or intense outdoor activity. Take more breaks, do less intense activities. Schedule outdoor activities in the morning when ozone is lower. Additional Details: Unhealthy (Red) AQI ozone will be possible within the lake breeze from Sheboygan south to Kenosha. These ozone concentrations will be confined to the lake breeze, which should struggle to push inland given the breezy SSW flow. Inland of the lake breeze and further north along Lake Michigan and Green Bay, Unhealthy for Sensitive Groups (Orange) AQI ozone is expected.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
