Hot weather could make it hard for some people to breathe Friday in Indiana.
An air quality action day has been posted for at least 20 counties in central and southeastern Indiana. Officials say people who are sensitive to air quality might feel it when ozone levels are high, especially the elderly and anyone with a heart condition.
The sun and high temperatures can combine to turn vehicle exhaust and factory emissions into ground-level ozone.
The Indiana Department of Environmental Management ncourages everyone to help reduce ozone by making simple changes to their daily habits. You can:
• Walk, bike, carpool or use public transportation
• Avoid using the drive-through and combine errands into one trip
• Avoid refueling your vehicle or using gasoline-powered lawn equipment until after 7 p.m.
• Turn off your engine when idling for more than 30 seconds
• Conserve energy by turning off lights or setting the air conditioner to 75 degrees or above
Here are the counties where ozone could be high: Marion, Bartholomew, Boone, Brown, Delaware, Hamilton, Hancock, Hendricks, Johnson, Madison, Monroe, Morgan, Shelby, Clark, Floyd, Harrison, Jackson, Jefferson, Scott and Washington.
This follows air quality warnings in St. Joseph, Elkhart, LaPorte, Porter, Huntington, and Allen Counties yesterday.
