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 will remain across the central Gulf allowing
for generally gentle to moderate winds and relatively low seas
throughout the period. Moderate to fresh winds will continue to
pulse each evening through the early morning hours near and to
the NW of the Yucatan Peninsula in association with a local
trough.  

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

A tropical wave currently located near 76W will reach the
western Caribbean by late tonight, and move across this area
through Thu night. An active tropical wave will cross the Lesser
Antilles tonight and Thu and move across the eastern Caribbean
through Fri night. Shower activity ahead of this tropical wave
is already affecting the Windward Islands. Computer model
suggests increasing winds and seas as the wave moves across the 
central Caribbean. Currently, the forecast calls for 20-25 kt
winds and building seas to 10 ft. 

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

A ridge extending westward from the Bermuda-Azores high will
persist across the forecast waters through the period. The 
pressure gradient between the ridge and tropical waves moving 
westward across the Caribbean Sea will support moderate to 
locally fresh trade winds mainly across the waters S of 22N 
through Sun. An area of showers and thunderstorms located NE of 
Puerto Rico is associated with a surface trough, and will move 
northward along the western periphery of the aforementioned ridge
over the next few days. Winds and seas could be higher near 
tstms. The most recent scatterometer pass showed fresh to strong 
winds in association with this trough.
