The National Weather Service has confirmed that a strong EF-1 tornado did touch down in Cobb County during the Wednesday storms that downed trees, power lines and put a roof in a roadway.
The tornado touched down near Delta Circle Southeast, which is in an industrial area about a mile away from Six Flags Over Georgia, said Ryan Willis, NWS forecaster.
He said the tornado was 100 yards wide, gusted up to 100 mph and moved three-quarters of a mile northeast. That means the storm was 11 mph shy of becoming an EF-2.
The most significant damage in that area was to roofs and metal wall panels hit by debris along with poles knocked sideways, he said.
In Alpharetta, a weaker EF-0 storm touched down along Windward Parkway east of Ga. 400, Willis said.
"So far it looks like the tornadoes we have were short-lived with short paths and the damage was relatively limited," he said. "It definitely could have been worse with a stronger tract."
The agency has two crews out looking for storm damage throughout Cobb and north Fulton counties. He said at about 1:30 p.m. that one group was heading to assess damage in Banks County.
A firefighter with a volunteer fire department in Bloomingdale, Georgia, and his wife were two of the three people killed Wednesday in Tennessee because of the storm.
