Wider weather episode

Strong low pressure over the eastern Gulf of Mexico resulted in a slow-moving pre-frontal trough focusing heavy convective rainfall over portions of the middle and upper Florida Keys. One EF0 tornado was observed on Big Pine Key in association with a small supercell which evolved in advance of the passing squall line. In additional, strong winds associated with a convectively-induced mesoscale low pressure system over the middle and upper Florida Keys resulted in moderate to major coastal flooding near the shores of Barnes and Card Sounds.
