.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure will build and migrate toward the central
Atlantic early this week, while a surface low and associated front
moves across the western Atlantic. Winds will prevail from the
east-southeast today, becoming lighter and from the south on
Wednesday. By the end of the week, the potential for showers over
the local waters will increase as the front moves closer to the
area, and winds turn from the east to northeast. A long-period
northwesterly swell will spread across the Atlantic waters and local
passages around late Wednesday night or early Thursday, with another
swell from the north-northeast by the end of the weekend, resulting
in hazardous seas.
