Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea,
and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas

...GULF OF MEXICO...

Weak high pressure across the basin will maintain generally
tranquil conditions across the Gulf through the rest of the
week. A tropical wave in the central Caribbean has a high chance
of tropical cyclone formation by this weekend, and this system
is expected to approach the Yucatan Peninsula or Channel early
Sat and then emerge in the southern Gulf Sat night through Sun. 

...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

A strong tropical wave over the central Caribbean is producing
widespread thunderstorms and gusty winds as it moves W at 15 to
20 kt. This wave and associated surface low pressure should slow
down and turn W-NW in the western Caribbean at the end of the
week, and a tropical depression is likely to form by the weekend
in the NW Caribbean. There is a medium chance of tropical
formation through Fri morning, then a high chance through the
end of the weekend. Looking ahead, low pressure associated with
another tropical wave is expected to move across the Tropical N
Atlc waters late Thu and approach the Atlantic waters off the
Leeward Islands late Fri. This system also has a high potential
for tropical development.  

...SW N ATLANTIC INCLUDING THE BAHAMAS...

An elongated area of low pressure remains across the central
Tropical Atlantic, associated with a tropical wave. 
Environmental conditions are favorable for tropical development 
and a tropical depression is expected to form in the next day or
 so as the low pressure moves WNW at 15 to 20 mph. This system
is forecast to approach the Leeward Islands early Fri, move
across  or just north of the Virgin Islands and Puerto Rico Sat,
and then along northern Hispaniola and the Turks and Caicos
Islands Sat night through Sun.
