.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure ridge extending across the southwest
Atlantic and a distant area of low pressure north of the region will
promote light to moderate northerly winds through the end of the
week into the weekend. Strong northerly swells generated by the low
pressure system will continue to spread across the local Atlantic
waters and passages during the next several days, creating hazardous
seas through at least Thursday.
