.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A high pressure across the central Atlantic will maintain choppy
seas due to moderate to locally fresh east to east-southeast winds
across the region through tonight. Winds will shift from the east to
the northeast on Saturday as a frontal boundary moves eastward
across the western Atlantic. A prefrontal trough will increase the
potential for showers throughout the weekend, particularly on
Saturday. Deteriorating marine conditions are anticipated late
Saturday Night due to a long-period northerly swell.
