.SYNOPSIS...

Couple waves of low pressure over the deep south will move eastward

this afternoon, then exiting the Northeast Florida waters by sunrise
Sunday. This storm system will bring showers and a few embedded
storms to the waters this afternoon and end overnight. Small Craft
Advisory conditions will develop ahead of the front across the
offshore waters by midday and persist into Sunday morning as winds
turn northwesterly and then diminish late Sunday. Winds will shift
to north-northeasterly by Monday as high pressure builds over the
Mid-Atlantic states, then moves offshore into midweek with south to
