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...

An approaching tropical wave is advecting scattered showers 
over W Cuba and the Straits of Florida. The Bay of Campeche has 
similar showers due to another tropical wave. The remainder of 
the Gulf has fair weather. The pressure gradient across the Gulf 
supports light to moderate winds throughout. In the upper 
levels, an upper level high centered over southern Texas is 
producing NE upper level winds over the Gulf with upper level 
moisture. 

A surface trough will develop along the western Yucatan 
Peninsula during the late afternoons, then drift westward during 
the overnight hours and dissipate along 96W during the late 
mornings. The trough will support moderate to locally fresh winds
in the eastern Bay of Campeche every night. Otherwise, high pres
NE of the region will support gentle to occasionally moderate SE
to E winds over the basin the next several days. 

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

An upper-level low is centered near the Cayman Islands at 
18N82W. The low is enhancing scattered showers near the upper-low
center, together with a tropical wave along 81W. 

Strong nocturnal wind pulses are forecast along the coast of
Colombia N of 11N and Gulf of Venezuela with seas building to
10 ft through Tue. The tropical wave along 81W will continue to
move west across the western Caribbean through Sat. A second
tropical wave along 63W will move across the E Caribbean today
and Sat and the central Caribbean on Sun. A third wave over the
central Atlc will reach 55W on Sun.  

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

Scattered moderate convection is north of 28N and west of 76W
associated with a stationary front. The stationary front extends 
from 31N77W to central Florida and will gradually transition to 
a surface trough through tonight. The trough will then drift NW 
and inland over the SE CONUS by late Sat. Outside of 
thunderstorms, light to gentle winds will prevail N of 26N, while
mainly moderate to locally fresh winds will prevail S of 26N the
next several days. Strong E winds will occur along the N coast 
of Hispaniola each afternoon and evening through the middle of 
next week.
