ATLANTA (AP) — Despite warnings of a winter storm watch posted on large message boards over metro Atlanta interstates, the National Weather Service issued no such watch and requested that they be corrected.

It wasn't immediately clear why the interstate signs early Thursday warned of a winter storm watch when none had been issued.

National Weather Service meteorologist Brian Lynn said shortly before 6 a.m. Thursday that the messages appeared to be a mistake. He said the weather service contacted state officials to alert them to the messages and asked that they be changed.

WSB-TV reported that the messages were removed by dawn Thursday. The Georgia Department of Transportation didn't immediately return phone calls from The Associated Press.

The weather service is forecasting some precipitation and the potential for black ice on roadways.
