.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure extending from the western to central
Atlantic will maintain the local pressure gradient tight through
today. As a result, expect hazardous seas for small craft operators
due to confused seas associated with winds and a northeasterly swell
spreading across the local waters. An induced surface trough, north
of the islands, will weaken the pressure gradient and winds will
shift from the east to east- southeast by the latter part of the
week.
