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

High pressure ridge across the west Atlantic and weak surface trough

just east of the region will aid in creating a light to gentle east 

to northeast trade wind flow overnight through Friday. Fairly tranquil

seas are forecast to persist through Friday and into the weekend. 

Showers and isolated thunderstorms may however 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 late Friday through Saturday. This will increase the chance

for showers and isolated thunderstorms over the regional waters.
