SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS
A SURFACE HIGH PRESSURE STRENGTHENING ACROSS THE CENTRAL ATLANTIC
WILL PROMOTE MODERATE TO FRESH WINDS, WITH STRONGER GUSTS FOR THE
REST OF THE WEEK. THIS WILL RESULT IN CHOPPY TO LOCALLY ROUGH MARINE
CONDITIONS. SEAS WILL BUILD UP TO 6 FEET ACROSS THE OFFSHORE WATERS
AND LOCAL PASSAGES, WITH OCCASIONAL SEAS UP TO 8 FEET. A PASSING
TROPICAL WAVE WILL INCREASE SHOWERS AND THUNDERSTORMS ACROSS THE
REGIONAL WATERS THROUGH THIS AFTERNOON. HOWEVER, A SECOND TROPICAL
WAVE WILL ARRIVE LATER TONIGHT THROUGH THURSDAY AFTERNOON PROMOTING
SIMILAR WEATHER CONDITIONS. GUSTY WINDS, BRIEF PERIODS OF TORRENTIAL
RAINFALL, AND LOCALLY HIGHER SEAS ARE EXPECTED WITH THESE TROPICAL
WAVES.
