How north Georgia is impacted by landfalling tropical systems
ATLANTA — When you’ve lived in Atlanta or north Georgia for any variety of years, you already know that though we’re a whole bunch of miles away from the coast, we nonetheless get impacted by tropical techniques extra years than not.

The tornadoes normally occur within the outer rain bands of the storm, usually in the fitting entrance quadrant of the storm, the place probably the most wind shear and instability is current. These are normally transient and weak, however nonetheless may cause injury.
Many previous storms have produced quite a few tornadoes within the space. In 2021, the remnants of Fred spawned 7 tornadoes throughout the world.
