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

Light to gentle northerly winds are expected through Tuesday due 

to the effect of high pressure in the western Atlantic and newly 

named Tropical Storm Epsilon well northeast of the local area. 

A northeasterly swell generated by the Tropical Storm is forecast to

enter and spread across the Atlantic waters from Tuesday onwards. 

This will result in deteriorating and hazardous seas for the rest of 

the work-week and possibly into the upcoming weekend as a secondary 

northerly swell is also forecast to follow.
