What happened

The episode as NWS JAX wrote it up.

Deep tropical moisture was across the area with PWAT of 2.1 inches with deep layer WSW flow. A surface front meandered over SE Georgia. Slow storm motion of 8 kts favored slow storm motion, and multiple forcing mechanisms spawned widespread rainfall covered.
