.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure across the central Atlantic will continue
to promote moderate easterly winds across the region. Moderate to
locally fresh easterly winds are expected to return by early next
week. Therefore, small craft operators will likely be encouraged to
exercise caution. A tropical wave will approach the region by the
middle of next week, increasing moisture and the potential to observe
showers and thunderstorms.
