Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
503 PM EST Tue Jan 20 2026
.SYNOPSIS...
High pressure over the waters will begin to shift towards the east-
northeast tonight with winds shifting to northeasterly. Winds will
then gradually weaken on Wednesday and Thursday as high pressure
extends its axis across the southeastern states. A few showers will
be possible late this week ahead of a cold front that will be
entering the southeastern states on Friday. Chances for showers will
then increase this weekend as this frontal boundary moves slowly
southward across our local waters, providing for strengthening
northeasterly winds on Saturday that will shift to northwesterly on
Saturday night as this front shifts south of the northeast Florida
waters.
