.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A broad surface high pressure over the north-central Atlantic will
continue to promote moderate to locally fresh easterly winds across
the regional waters during the next few days, keeping choppy to
occasionally rough seas. Hazardous marine conditions are forecast due
to a north-northwesterly swell spreading across the local Atlantic
waters and passages from this evening through Thursday evening. As a
result, Small Craft Advisories will be in effect starting this
evening.
