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

A long dominant period northeasterly swell generated by Hurricane  

Epsilon will continue to spread across the Atlantic waters and 

Caribbean Passages through the end of the work-week. This swell will

create hazardous marine conditions possibly into the upcoming 

weekend, as the combination of secondary northerly swell and an 

easterly wind driven swell invades the regional waters.
