A dynamic storm system impacted northeast Florida during the pre-dawn hours of December 14, 2019. A broken squall line of supercells moved quickly east to northeast across Alachua, Putnam, St. Johns and Flagler counties with two prominent mesocyclones producing tornado touchdowns and wind damage from Micanopy south of Gainesville to Flagler Beach. Thankfully, there were no reports or injuries or deaths, but there were widespread reports of structural and tree damage.
