ATLANTA (AP) — The powerful thunderstorms that passed through metro Atlanta earlier this week produced five tornadoes, but no serious injuries, authorities said Thursday.

The strongest twister struck Tuesday and traveled 7.5 miles through the northern suburbs of Alpharetta and Milton, according to a report from the National Weather Service. Crews that surveyed damage estimated that tornado's maximum wind speed at 105 mph.

The weather service said the five tornadoes began with a pair of twisters in the East Point and Camp Creek Parkway area near Atlanta's southern edge.

The twisters snapped trees in several communities, including neighborhoods in the Vinings area and in eastern Cobb County. Some homes were also damaged by trees falling on them.

"It should be noted that the tornadoes, although semi-continuous, were all spawned by the same storm that moved through the area," the weather service said in a report on damages.

A separate tornado Tuesday touched down near the west Georgia town of Shiloh in the pre-dawn hours. It tore part of a roof from a home on the south side of Pine Mountain and also destroyed a large shed, authorities said.

All six of the tornadoes were rated either EF-0 or EF-1 -- both considered weak tornadoes -- on the Enhanced Fujita Scale, the weather service said. EF-0 tornadoes have estimated wind speeds of 65-85 mph; EF-1 tornadoes have wind speeds of 86-110 mph.
