Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
449 PM EST Fri Dec 5 2025
.SYNOPSIS...
Weak low pressure moving across our region late this afternoon will
bring an increasing chance for showers and possibly an isolated
thunderstorm through this evening before this feature moves offshore
tonight. A cold front will then cross the northeast Florida waters
overnight before stalling over north central Florida on Saturday and
Saturday night. A wave of low pressure will then develop along this
front just south of the northeast Florida waters on Saturday night,
with widespread rainfall and a few embedded thunderstorms
overspreading our local waters through Sunday evening. Low pressure
will move offshore on Sunday night, resulting in strengthening
northwesterly winds. High pressure will then build over the
southeastern states early next week, creating strengthening
northerly winds and Small Craft Advisory conditions from Monday
afternoon through Tuesday evening.
