1245 PM EST Sat Dec 27 2025
.SYNOPSIS...
High pressure will remain centered over the southeast Gulf and
southern Florida peninsula through the weekend. 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. West-southwesterly winds increase to
Caution levels on Monday ahead of an approaching front. Winds shift
to northwesterly and strengthen to Small Craft Advisory levels
Monday night into Tuesday in the wake of the frontal passages. West-
northwesterly winds continue for much of next week as high pressure
builds eastward along the northern Gulf coast.
