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

A broad surface high pressure extending across the region from the 

north-central Atlantic will promote moderate east winds today. This

will result in choppy seas, mainly across the offshore Atlantic

waters. Winds and seas will then gradually diminish and subside through

the rest of the work week. Shower and isolated thunderstorm activity

will continue over the regional waters today.
