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.
