.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters....
A tropical wave moving across the Caribbean will continue to support
showers and isolated thunderstorms over the local waters through
late tonight. Meanwhile, a broad surface high pressure system over
the central Atlantic will maintain moderate to locally fresh
easterly to east-southeasterly winds through the next several days,
resulting in choppy seas across the local waters and Caribbean
passages. Small craft should exercise caution. In addition, moderate
to occasionally high concentrations of Saharan dust will persist
into early next week, producing hazy skies, reduced visibility, and
poor air quality.
