North Georgia is waking up to heavy rain, severe thunderstorms and lots of traffic problems Friday morning.

Multiple counties have been under tornado warnings, and Channel 2 Action News meteorologist Brian Monahan said the atmosphere is right at any time for a brief, isolated tornado anywhere across North Georgia as a system of strong storms moves through the state.

There have been no reports of any confirmed tornadoes, but damage has been reported across metro Atlanta.

“A very active morning, and it’s going to stay this way over the next several hours,” he said.

The worst of the storms has moved out of metro Atlanta, but Monahan said heavy rain, strong winds and lightning will continue and have the potential to cause major traffic headaches through the peak of the morning rush.

UPDATE [10:38 a.m.]: As heavy rain winds down in metro Atlanta, the severe weather risk is shifting east.

The National Weather Service has issued a tornado watch for Elbert and Hart counties in east Georgia. Damaging wind and heavy rain is still possible through the afternoon, according to Channel 2 Action News.

The watch is set to expire at 5 p.m.

Southwest of the city, all the rain Friday morning has washed away part of Wright Road in Troup County. A large portion of the road has collapsed.
