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

Winds will remain mostly from northeast today, then gradually 

diminish and become southerly as Major Hurricane Teddy moves 

northwestward across the Atlantic and stay well north of the region

through the weekend. Northeasterly swells generated by Teddy will 

continue to spread across the regional waters resulting in extremely

hazardous marine conditions through at least Monday. Therefore, 

Small Craft Advisories are in effect for most of the waters.
