SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS
The broad surface high pressure will continue to strengthen over the central Atlantic during the next few days, tightening the local pressure gradient, and promoting fresh to locally strong easterlies through much of the work-week. This strong surface high pressure will maintain a cold front, now over the Western Atlantic, without reaching the northeastern Caribbean early this week.
