959 AM EST Fri Jan 16 2026

SYNOPSIS

Subsiding winds and seas continue this morning as high pressure moves across the N Gulf, with any residual advisory criteria seas expected to abate this morning. No headlines expected until Sunday when a cold front pushes across the waters bringing another round of hazardous conditions including N/NW winds likely reaching advisory level before subsiding on Monday. High pressure then moves across the SE U.S. north of the waters over the early part of the week potentially causing late night through early morning cautionary level NE winds, but diminishing after mid week.
