.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Showers and isolated thunderstorms will continue to affect the local
waters for the next several days as lingering moisture from a
surface trough and an old frontal boundary remains over the local
area. Gentle to moderate northeast winds will continue today. Then,
winds will increase from moderate to fresh tonight through at least
Tuesday night under the influence of a surface high pressure moving
off the eastern coast of the United States. Increasing winds and a
northerly swell spreading across the local waters on Monday will
further deteriorate seas through at least mid-week.
