Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1028 PM EST Fri Jan 17 2025
.SYNOPSIS...An area of weak low pressure over the southeastern
Gulf of Mexico will continue moving northeastward overnight
resulting in gentle to moderate breezes. As the low pulls away
Saturday, breezes will slacken to light to gentle. Light to gentle
breezes are expected through Sunday out ahead of the next cold
front. A first cold front is expected to push through the Keys
coastal waters Sunday night and Monday resulting in freshening
north to northeasterly breezes. In its wake, breezes modestly
slacken before another more potent cold front may move through the
Keys towards mid week bringing potentially a stronger surge of
north to northeasterly breezes.
