A widespread severe weather event is already underway today with numerous tornadoes already reported. The Storm Prediction Center (SPC) has already issued a PDS (Particularly Dangerous Situation) Tornado Watch for portions of Tennessee, Kentucky and Illinois with additional watches to be issued later. The SPC has outlined north Georgia in the Moderate Risk area and that area is right at the edge of Gwinnett County, I would go ahead and consider us to be in that area.
Here's the latest NWS update from the Atlanta National Weather Service Office:
