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

A weak tropical wave is approaching the area, and continues to bring

showers and thunderstorms across the local waters, with increasing 

activity tonight into tomorrow morning. Drier, more stable weather

conditions are expected for midweek. Seas will remain relatively 

tranquil across the local waters, and gentle to moderate easterly 

winds continue. Model guidance still suggests increasing seas for the

local Atlantic waters starting Friday, due to a northeasterly swell,

but changes are possible.
