(Indianapolis, IN) - The Indiana Department of Environmental Management is forecasting an Air Quality Action Day on Saturday for North Central and Northwest Indiana.
Ozone levels are expected to be in the Unhealthy for Sensitive Groups range in the following areas:
- North Central Indiana, including the cities of Elkhart, Goshen, Knox, Logansport, Plymouth, Peru, South Bend, Warsaw, Winamac, and all other cities within the area.
- Northwest Indiana, including the cities of Crown Point, Gary, Hammond, Kentland, LaPorte, Michigan City, Portage, Rensselaer, Valparaiso, and all other cities within the area.
High temperatures are expected to reach the 80's on Saturday which is well above seasonal averages for this time of the year and combined with mostly sunny skies, low humidity, and a lake breeze, may lead to ozone levels increasing to unhealthy for sensitive groups.
