.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A broad surface high pressure over the central Atlantic will promote
fresh to locally strong easterlies today and tonight which will in
turn deteriorate marine conditions, before weakening and resulting in
more moderate to fresh easterly flow for the rest of the week. Small
Craft Advisories will remain in effect through at least the rest of
the workweek. A surface trough will move across the Northeast
Caribbean today, affecting the region through Saturday and increasing
shower frequency. A northerly swell is also forecast to arrive by
late Monday night.
