Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 22N between 55W and 64W, the SW N Atlantic S of
31N W of 65W including Bahamas, and the Caribbean Sea.

Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...Moderate to fresh trade winds will dominate much of
the basin. Long period northerly swell will starting pushing
through Atlantic passages by Tue. A tropical wave entering the
central Caribbean will move through the western Caribbean by
late Tue, and west of the basin by mid week. Scattered
thunderstorms and gusty winds accompany another tropical wave
approaching Barbados. This wave will move through the eastern
Caribbean today, across the central Caribbean through mid week,
and into the western Caribbean by late week. Looking ahead, low
pressure developing east of the area will move toward the
Atlantic offshore waters of the Leeward Islands by late Fri,
possibly as a tropical cyclone.
