.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A fading pre frontal trough north of the area will keep light to
gentle southeasterly winds this evening, becoming moderate from the
east after midnight due a surface high pressure over the Central
Atlantic. Pulses of a north northeasterly swell will continue to
spread across the Atlantic waters and local passages through
Wednesday. Another approaching pre frontal trough will promote winds
from the northeast later in the workweek.
