457 AM AST Mon Nov 25 2024

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A frontal boundary extending from the windward passage into the
Atlantic Ocean north of PR and the USVI will induce a pre-frontal
trough near the islands, promoting shower activity across the local
waters and passages. A north northwesterly swell will gradually fill
today and deteriorate the local marine and coastal conditions
through at least mid-week. The frontal boundary will linger north of
the islands while a surface high pressure builds from the western
Atlantic to the central Atlantic, with moderate to locally fresh
trade winds.
