FORSYTH COUNTY, Ga. -- New data from the National Weather Service (NWS) leaves little room for doubt that residents in northern Fulton and southern Forsyth counties felt the effects of a tornado on Wednesday.

Surveying crews have confirmed that an EF-0 tornado as well as heavy storms came through the area.

While this is the lowest rating for a tornado on the Enhanced Fujita Scale, it was enough to generate 80 mph winds.

Officials believe the storm first touched down at around 2 p.m. about 3.5 miles northeast of Alpharetta. It then cut a 3.5 mile path near Windward Parkway.

That's where the storm is believed to have uprooted two pine trees. It then continued into southern Forsyth County.

There, it snapped several trees on McGinnis Ferry Road and damaged a traffic light near the intersection with Curie Drive.

Additional trees and limbs were downed along its path before the storm lifted near Ridgefield Drive.

The NWS reports this was in the span of about 6 minutes.

It was one of four tornadoes confirmed so far in metro Atlanta. Others were confirmed in Atlanta's Buckhead community, Commerce, Ga. and Cobb County near Mableton, Ga.

All instances so far ranged from EF-0 to EF-1 - on the lower end of the scale but still capable of causing significant damage.
