.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Tropical Storm Jerry continues to move northeast of the islands,
aroun 151 miles of St. John and about 209 miles of San Juan. This
system will continue moving northwestward at a safe distance from
Puerto Rico and the USVI. Although no direct tropical storm impacts
are expected, indirect marine impacts will continue spreading across
the regional waters from late tonight and Saturday. Swells generated
by Jerry will lead to hazardous seas up to 8 to 9 feet, particularly
across the offshore Atlantic waters and the Anegada Passage, where a
Small Craft Advisory is in effect through tomorrow morning. Conditions
are forecast to gradually improve late Saturday onwards.
