ATLANTA (AP) — Parts of Georgia will be under a heat advisory as temperatures climb into the upper 90s in large parts of the state, with heat index values soaring to around 105 degrees.

Forecasters say the advisory is scheduled to be in place from noon to 8 p.m. Wednesday in a large part of central and south Georgia. It includes the cities of Athens, Columbus, Macon, Statesboro and Vidalia.

The National Weather Service is projecting high temperatures of around 100 degrees across south Georgia, including the Dublin and Hinesville areas. Highs are expected to reach the upper 90s in many other areas of the state.

Elsewhere, state environmental officials issued a code orange air quality alert for metro Atlanta on Wednesday. Officials say outdoor air could cause breathing problems for some people.
