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

Light to moderate northeast winds will persist across the regional 

waters through the end of the workweek, then gradually diminishing 

and becoming southerly as the Major Hurricane Teddy moves 

northwestward across the Atlantic and well northeast of the local 

region during the weekend. However, northeasterly swells generated by

Teddy will arrive and spread across the regional waters resulting in

hazardous marine conditions through at least late Sunday night or

even early Monday morning.
