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

.SYNOPSIS...A strong tropical wave - Invest 97L - 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 from Sun through at least Tue
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 SE Bahamas, 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 generally 
moderate or weaker for the next several days.
