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

As a surface trough moves away from the region, lingering showers

will continue to affect the local waters. A small northeasterly swell

will reach the local waters tomorrow and continue through the end of

the week, but seas are expected to generally remain at 5 feet or 

less. A tropical wave will reach the islands on Thursday, which 

should result in additional shower activity over the waters.
