The National Weather Service (NWS) issued a special weather statement late Saturday evening and a hazardous weather outlook Sunday morning.

Patchy fog is expected across the region until 10 a.m. Sunday, January 12, and the combination of overnight subfreezing temperatures and the partial thawing of slush in the roadways will cause icy patches.

The special weather statement gave the following caution:

…ICY ROADS EXPECTED TONIGHT ACROSS NORTH AND CENTRAL GEORGIA… Sub-freezing temperatures tonight, coupled with lingering moisture and slush on roadways, will lead to slick spots and patches of black ice. Ice on roads can be very difficult or impossible to see at night. Temperatures across most areas will drop below freezing by early Saturday evening, with temperatures not rising above freezing until at least mid-morning Sunday. Use extra caution while driving and slow down to reduce your risk. Avoid sudden breaking or rapid lane changes if possible.
