The National Weather Service (NWS) says damaging hail, strong winds, heavy rain and sharp lightning are possible.
The affected area stretches from as far south as Macon and Columbus to the borders with Tennessee and the Carolinas.
Forsyth County was one of several places in north Georgia where there was wind damage yesterday.
Forsyth County Fire Capt. Jason Shivers told Channel 2 Action News that the storms, packing strong winds and heavy rains, pounded the Cumming area for nearly two hours before moving on.
"(There were) numerous reports of trees down across power lines, across roadways and on houses," Shivers said.
Among the areas where damage occurred was the Polo Fields Subdivision.
