.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...
Moderate to locally fresh east to east-southeast winds will prevail
through the weekend as the surface pressure gradient tightens across
the regional waters. A north-northwesterly swell will maintain seas
between 5 and 7 feet across the Atlantic waters and the Mona Passage
today, followed by reinforcing northerly swell pulses through early
next week. Small Craft Advisories remain in effect for the Atlantic
waters and the Mona Passage through at least Saturday. Isolated
thunderstorms with scattered showers are expected to continue across
the Caribbean and western waters of PR today, where locally higher
seas and strong gusty winds are possible.
