.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure building over the Western Atlantic will
promote moderate to locally fresh easterly winds. As this system
spreads into the central Atlantic and a surface low pressure and
associated frontal boundary approaches the region from the northwest,
winds will weaken and become more southeasterly by Sunday into early
next week. A long period northerly swell will arrive by Tuesday,
promoting hazardous seas through at least Thursday.
