The Indiana Department of Environmental Management (IDEM) has forecast an Air Quality Action Day (AQAD) for Friday
Fine particulate matter levels are expected to be in the Unhealthy for Sensitive Groups range (Orange) in the following areas:
- Central/East Central Indiana, including the cities of: Bloomington, Brookville, Columbus, Frankfort, Indianapolis, Greensburg, Kokomo, Lebanon, Martinsville, Muncie, Richmond and all other cities within the area.
- Western/West Central Indiana, including the cities of: Crawfordsville, Covington, Delphi, Fowler, Greencastle, Lafayette, Newport, Monticello, Spencer, Sullivan, Terre Haute and all other cities within the area.
Hot temperatures, sunny skies, and light winds are expected tomorrow as high pressure settles over the region, creating very stable atmospheric conditions. This stability is likely to cause a buildup of fine particulates. When combined with additional emissions from fireworks, air quality could reach levels in the Unhealthy for Sensitive Groups (USG) range—both on an hourly basis and potentially over the full 24-hour period. Elevated PM2.5 concentrations are expected across Central/East Central, and West Central Indiana.
Hoosiers can visit SmogWatch.IN.gov to:
- View Air quality information for all Indiana counties, including a state map of affected counties;

Air Quality Action Days are in effect from midnight to 11:59 p.m. (24-hours) on the specified date. Some municipalities have additional open burning restrictions on AQADs.
