.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. A large northerly swell generated by the before
mentioned low pressure will continue to affect the local Atlantic
waters including all local passages. This swell event already peak
and now is slowly subsiding but dangerous and hazardous marine
conditions will prevail through the weekend. Another pulse of energy
in the form of swells will affect the same areas early Sunday
morning.
