.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
The surface high pressure across the central Atlantic will continue
to promote a moderate easterly wind flow across the local waters.
The easterly trade winds will bring occasional patches of low level
clouds and showers across the coastal waters overnight. A tropical
wave is forecast to cross the Lesser Antilles and enter the eastern
Caribbean by Saturday. This will increase the chance for thunderstorm
activity with areas of locally heavy rains across the regional waters
Sunday through Monday.
