.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Gentle to moderate and variable winds will prevail over the next few
days. Marine conditions will become unfavorable for small craft
this morning as moisture remnants along a cold frontal boundary sink
southward across the region. This will increase the chance for
showers and isolated thunderstorms across the regional waters and
passages. Pulses of a northerly swells are expected to arrive and
create hazardous seas today, stretching into the weekend.
