The Wisconsin Department of Natural Resources has issued an Air Quality 

Advisory for the following counties: Brown, Calumet, Door, Kewaunee,

Manitowoc, Marinette, Oconto, Outagamie and Winnebago.



WHAT...The Ozone AQI is expected to reach the Unhealthy for Sensitive 

Groups (Orange) level.



WHERE...Eastern Wisconsin.



WHEN...Until 11 p.m.



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.
