.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
As the pressure gradient weakens across the northeastern Caribbean,
winds will remain gentle to moderate from the east to northeast with
seas of 3 to 5 feet. These improving marine conditions will persist
through today and into the early part of the weekend. However,
another area of high pressure building across the northwestern
Atlantic by late Saturday into early next week will tighten the
pressure gradient. Winds are expected to increase (fresh to strong
trades) Saturday night into Sunday, resulting in deteriorating marine
conditions with rough and choppy seas across our regional waters and
local Caribbean passages. Small Craft Advisory conditions are likely
from late in the weekend into early next week, with seas building to
around 6 to 8 feet.
