Ozone levels are expected to be in the Unhealthy for Sensitive Groups range (Orange) in the following areas:

• Southeast Indiana, including the cities of: Brownstown, Corydon, Jeffersonville, Madison, New Albany, Salem, Versailles and all other cities within the area.
• Southwest Indiana, including the cities of: Bedford, Bloomfield, Evansville, Huntingburg, Mount Vernon, Paoli, Princeton, Rockport, Tell City, Vincennes and all other cities within the area.

A system of high pressure across the lower Ohio Valley has allowed some light smoke to reach the surface. This combined with light winds and sunny skies may lead to ozone levels that reach the Unhealthy for Sensitive Groups (USG) range in these areas.
