Atlanta is fortunate to be nestled in the valley east of the Blue Ridge Mountains. Hurricanes are not frequent here in Atlanta nor are Natural Disasters. In living here for 14 years, I HAVE seen "tropical systems" move through Atlanta where high winds, >40 MPH, and localized flooding occur. This has occured around 3 times in the past 10 years.
Recently, a tornado, F2, ripped through downtown Atlanta causing damage to windows and the Fulton Cotton Mill Lofts as well as one in Woodstock which cut some trees in half and pelted some homes with 2" hail.
Altanta typically has severe thunderstorms in the spring and fall seasons when a weather front passes through and has high humidity in the summer. Another fact to consider when moving to a particular area around Atlanta is whether/ or not the city has a Warning Siren. most cities around Atlanta which had systems in place have let them fall to disrepair because of budget constraints and lack of public concern. Of late, this is slowly changing.
