(Indianapolis, IN) - La Porte County is included in a high ozone-related advisory for Tuesday.

The Indiana Department of Environmental Management has issued an Air Quality Action Day due to high ozone being in the forecast for Tuesday. The advisory is for La Porte, Michigan City, Knox, Valparaiso, Plymouth and other cities throughout much of northern Indiana.

A state map including regions and affected counties is available at SmogWatch.IN.gov. 

Continued sunny skies with highs in the upper 80's with east winds will contribute to high ozone, IDEM noted, encouraging everyone to help reduce ozone by making changes to daily habits such as driving less, carpooling, using public transportation, walking and biking.

Ground-level ozone that can irritate the lungs is formed when sunlight and hot weather combine with vehicle exhaust, factory emissions, and gasoline vapors.
