.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...

Although the pressure gradient will relax across the Northeast
Caribbean tonight and tomorrow, choppy seas will continue due to
moderate to locally fresh easterly winds across the region. Saharan
dust particles will be in place, resulting in hazy skies throughout
Sunday night. Another tropical wave will move near the region around
Monday, increasing once again the chance for shower and thunderstorm
development.
