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...

A cold front is approaching the NW gulf waters. The front will 
stall near the upper Texas and Louisiana coasts tonight, then 
return N as a weakening warm front Thu. Scattered showers and 
thunderstorms in the vicinity of the front could produce brief 
gusty winds and higher seas. A surface trough is expected to form
each day over the Yucatan Peninsula, then move over the Bay of 
Campeche at night. Fresh to locally strong winds will be possible
over the eastern waters of the Bay of Campeche from sunset to 
around midnight as the troughs move offshore. Otherwise, ridging 
extending WSW from the western Atlantic will generally maintain 
moderate ESE to SE return flow over the basin through Sat night.


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

Strong NE to E trades are expected over the central Caribbean 
through Wed night. The area of strong trades will then shrink in 
size and become more closely confined along the coast of Colombia
through Sat night as the ridge to the N is weakened slightly by 
an area of mid to upper-level low pressure passing near or N of 
the Bahamas. Strong winds will pulse over the Gulf Honduras each 
night through Sat. Moderate to fresh trades will prevail over the
eastern Caribbean, and gentle to moderate trades over the 
western Caribbean. Scattered showers and thunderstorms over the 
tropical N Atlantic waters in advance of a tropical wave will 
continue W and reach the far SE Caribbean Thu. This activity will
move across the eastern Caribbean through Sat. 

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

A strong Atlantic high pressure ridge extending from the Azores 
to central Florida will lift N toward Cape Hatteras by the end of
the week. Fresh to occasionally strong trade winds are expected 
near the N coast of Hispaniola through Sat night. Winds will be
light to moderate over the waters N of 22N.
