.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
As a frontal boundary and pre frontal trough approach the region,
winds will veer from the east southeast and gradually diminish
through the weekend, with locally higher winds possible today across
the Mona Passage. Seas will slowly subside, but choppy to rough
conditions will persist across portions of the local waters. A Small
Craft Advisory remains in effect for the offshore Atlantic waters
through this afternoon. Elsewhere, small craft should exercise
caution. Winds will shift back from the northeast early next week,
with marine conditions generally improving, although unsettled
weather will persist.
