.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A frontal boundary approaching from the western Atlantic will
continue to weaken the pressure gradient associated with the broad
surface high pressure extending from the eastern to central Atlantic
resulting in light southerly winds for tonight. For Thursday ven
lighter from the east to northeast on Thursday into Friday due to the
influence of a col region. Additionally, a long- period
northwesterly swell is expected to arrive next Saturday, likely
deteriorating marine conditions across the Atlantic waters and
northern local passages.
