While gusty downdraft winds in excess of 60 mph are the biggest threat, a brief, weak spin-up tornado can't be ruled out. This is especially possible with bowing line segments or any thunderstorms that are able to form ahead of the main line.
Flash flooding from heavy rain is also a concern region-wide. Rounds of rain could produce in excess of 3-4" in some spots. Flood alerts are in place for southwest Georgia and Florida and the midlands of South Carolina.
