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

A slowly subsiding northerly swell combined with moderate to fresh 

easterly winds will create confused seas through today. Although, the

swell subsides by Wednesday, the persistent moderate to fresh tradewinds

will aid in maintaining choppy and hazardous seas through the end of

the week. An easterly disturbance will continue to move across the 

local waters today increasing shower and thunderstorm activity over 

the local waters. A tropical wave will move across the regional 

waters Wednesday through Thursday to maintain the potential for 

thunderstorm development with areas of locally heavy rainfall and 

brief gusty winds.
