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

A long 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.
