Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
752 AM EST Sat Dec 27 2025
.SYNOPSIS...
High pressure will remain centered over the southeast Gulf and
southern Florida peninsula through the weekend. Breezy westerly
winds early this morning offshore will diminish this afternoon. High
pressure will then weaken and slide southward on Sunday night ahead
of a strong cold front, which may bring a few showers to our local
waters on Monday afternoon and evening. Southwesterly winds will
develop ahead of this approaching front on Sunday night, with speeds
gradually strengthening on Monday before shifting to westerly on
Monday evening as the front crosses our region. Speeds will increase
to Caution levels early on Monday evening before strengthening to
Small Craft Advisory levels towards midnight as winds shift to
northwesterly following the passage of the front. Small Craft
Advisory conditions will likely continue through Tuesday morning,
and breezy northwesterly winds will continue in the wake of this
frontal passage for much of next week as high pressure builds
eastward along the northern Gulf coast.
