.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure building over the western Atlantic will
yield moderate to locally fresh easterly winds, causing
marine conditions to deteriorate during the weekend. These winds
will push fragments of moisture from a frontal boundary north of the
islands into the local waters. Marine conditions are expected to
deteriorate further on Tuesday as a long-period northerly swell
arrives.
