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



A ridge of high pressure across the western Atlantic and a weak 

surface trough just east of the region will aid in creating light to 

gentle northeast to east trade winds today. Gentle seas are forecast 

to persist through the weekend and become more tranquil by mid week. 

Showers and isolated thunderstorms may affect parts of the coastal 

waters mainly during the afternoon and early evening hours. A 

tropical wave is forecast to enter and move across the eastern 

Caribbean today through Saturday with an increased chance of 

showers and thunderstorms.
