.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...

A tropical wave continued to exit the region this morning, bringing 

an increase in showers and thunderstorms across the local waters. A 

wind surge is anticipated behind this wave, and will combine with a 

small swell to bring seas of up to 7 feet to the outer Atlantic 

waters, then spreading into the Anegada Passage. Hazardous seas are 

forecast to last through Wednesday in the outer Atlantic waters, but

will brief in duration elsewhere. Subsiding seas are forecast beyond

Wednesday as winds and seas are forecast to diminish.
