.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 Tropical 

Storm Epsilon well northeast of the local area. A northeasterly swell

generated by Epsilon is forecast to enter and spread across the Atlantic

waters later today through the end of the week. This will result in 

deteriorating and hazardous seas possibly into the upcoming weekend 

as a secondary northerly swell is also forecast to follow.
