The Indiana Department of Environmental Management is predicting worse air quality for several counties in Indiana today (Tuesday).

The agency has issued an air quality action day for Delaware, Marion, Bartholomew, Boone, Brown, Hamilton, Hendricks, Howard, Madison, Shelby, Clark, Floyd, Daviess, Dubois, Gibson, Greene, Knox, Perry, Pike, Posey, Spencer, Vanderburgh, Warrick, Vigo, Carroll, and Tippecanoe counties.

Children, seniors and anyone with a heart or lung condition should avoid strenuous work or outside exercise.

IDEM says hot weather and pollution from things like cars and factories creates more ground-level ozone. That can make it more difficult to breathe and cause coughing. People can help reduce ground-level ozone by walking, biking, or working from home. If you do have to drive your car, IDEM says make fewer trips and turn off your engine if you’re idling for more than 30 seconds. You can also set your home thermostat to higher than 75 degrees.

Additionally a Heat Advisory has been issued for counties north of Muncie, for Tuesday.
