.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Surface high pressure will move into the west and central Atlantic
later today producing moderate to locally fresh trade winds
through Tuesday. Due to the strengthening high pressure a strong
local pressure gradient will form across the region, increasing
the trade wind flow. A long dominant period northerly swell will
continue to spread across the Atlantic waters and passages through
Wednesday.
