Dangerous Severe Weather Outbreak Underway

Stay alert for Severe Weather Updates

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:

.UPDATE... HAVE MADE MANY UPDATES TO FORECAST PRODUCTS TO REFLECT CHANGES IN ENVIRONMENT. CONVECTION AHEAD OF THE FRONT CURRENTLY ACROSS NORTHERN AL AND TN HAS DEVELOPED IN A SUPPORTIVE ENVIRONMENT...ALLOWING FOR HAIL PRODUCING CELLS WITH ELEVATED ROTATION.
