.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 northeast of the region
will promote light to moderate north to northwest winds through the
end of the week. A large northerly swell generated by the before
mentioned low pressure will continue to affect the local Atlantic
waters including all local passages. Although this swell is slowly
subsiding, dangerous and hazardous marine conditions will continue
tonight and Friday. Another pulse of energy in the form of swells
will affect the same areas by Saturday night.
