Sixteen Wisconsin counties will remain under an ozone advisory until 11:00 p-m.  The Wisconsin Department of Natural Resources says the air quality index could be unhealthy for sensitive groups in the area.  The D-N-R is talking about children, the elderly, active individuals, and people with lung diseases.  Most of the problem areas are in southeastern Wisconsin, but Brown and Kewaunee counties in the northeast are also on the list.

Brown, Calumet, Door, Fond du Lac, Kenosha, Kewaunee, Manitowoc, Marinette, Milwaukee, Oconto, Ozaukee, Racine, Sheboygan, Walworth, Washington, and Waukesha.
