31N W of 55W including the Bahamas, and the Caribbean Sea.

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

.SYNOPSIS...A strong tropical wave moving westward will cross
the central Caribbean through Fri and the W Caribbean through
Sat night. While the wave will bring scattered showers and
isolated thunderstorms, it will also break up the dominance of
the Atlantic ridge over the basin and allow winds and seas to
diminish some across the central and W Caribbean through Sun
morning. Looking ahead, winds and seas will increase again
across the central Caribbean by late Sun as high pressure builds
in the wake of the tropical wave.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A well-defined tropical wave is producing a large 
area of disorganized showers and thunderstorms over Hispaniola, 
Puerto Rico, the Virgin Islands, and the adjacent waters of the 
southwestern N Atlantic. Development of this system should be 
slow to occur during the next couple of days while it moves
west-northwestward over portions of the Greater Antilles. There 
is a low chance of the system becoming a tropical depression 
within the next two days over the waters just north of the 
Greater Antilles including the Bahamas before the wave reaches 
the Gulf of Mexico. Elsewhere, the trades will remain moderate or
weaker for the next several days.
