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 the Atlantic Ocean passages by Tuesday. A tropical wave
entering the central Caribbean Sea will move through the western
Caribbean Sea by late Tuesday, and to the west of the basin by
middle of the week. Scattered thunderstorms and gusty winds
accompany a second tropical wave that is approaching Barbados.
The second tropical wave will move through the eastern Caribbean
Sea today, across the central Caribbean Sea through mid week,
and into the western Caribbean Sea by late week. A low pressure
center, that is developing to the east of the area, will move
toward the Atlantic Ocean offshore waters of the Leeward Islands
by late Friday, possibly as a tropical cyclone.
