.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...

Surface high will shift toward the east on Sunday, relaxing the
pressure gradient a little. As a result, winds will become light to
moderate and seas will gradually subside. Easterly trade winds are
expected to strengthen again by Tuesday into Wednesday as another
surface high builds across the western Atlantic, resulting in
increasingly choppy marine conditions. A tropical wave will move over
the Caribbean Sea late Wednesday into Thursday, increasing the
potential for showers and thunderstorms.
