.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Surface highs over the central Atlantic will maintain an easterly
moderate to fresh breeze through the weekend. These conditions will
keep rough to hazardous seas across the offshore Atlantic waters and
the Anegada Passage, where Small Craft Advisories remain in effect
through Friday. Boaters should also use caution across all other
local waters, including the waters surrounding the U.S. Virgin
Islands, as choppy seas and occasional stronger winds may still
create challenging conditions. Even after advisories expire, breezy
conditions and choppy seas up to around 6 feet, especially across the
Atlantic waters, are expected to continue into early next week.
