Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
733 AM EDT Sun Aug 31 2025
.SYNOPSIS...
High pressure to the north of the region will wedge down the
southeastern seaboard, sending a surge of northeasterly winds and
building seas across our local waters from north to south today.
Small Craft Advisory conditions will overspread the waters reaching
the waters south of St. Augustine by late this afternoon. Waves of
showers and embedded thunderstorms will impact our local waters
through midweek. Northeasterly winds will begin to gradually weaken
by late Tuesday and Wednesday, allowing for seas to gradually
subside. Coverage of showers and thunderstorms will then decrease
later this week as prevailing winds shift to westerly ahead of a
series of approaching cold fronts.
.GULF STREAM...
