.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...
A surface high pressure extending from the Central into Eastern
Atlantic is interacting with a frontal boundary approaching from the
western Atlantic, promoting light to moderate northeasterly winds. A
long-period north-northwesterly swell is expected to arrive tonight
and spread across the local Atlantic waters, resulting in hazardous
conditions for small craft. Although the swell will diminish by late
Thursday night into Friday, another long-period swell from the
north-northeast should arrive on Saturday, however, seas are expected
to remain below small craft advisory criteria.
