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 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 NE
to E 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...

Fresh to strong winds will prevail at night in the south-central
Caribbean with the strongest winds along the coast of Colombia
where winds may increase to near gale force. Seas will be in the
range of 8 to 10 ft during that period. Otherwise, a tropical
wave along 85W will continue to support scattered showers and
tstms in the NW and SW Caribbean through Sat night. A second
tropical wave along the Mona Passage will move across the
central basin Sat enhancing isolated showers in Hispaniola. A
new tropical wave is expected to move across the Lesser Antilles
Tue night to Wed bringing showers to the E basin. 

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

The remnants of a weakening stationary front will transition to
a surface trough on Sat morning. Showers and isolated tstms will
continue NW of the northern Bahamas through Sun when the trough
is forecast to move across Florida before moving into the E Gulf
of Mexico. Similar convective activity is forecast for the
remainder area W of 70W being enhanced by an upper level low and
diffluent flow aloft. Weak surface ridging will prevail
elsewhere supporting light to gentle variable winds E of the
Bahamas and moderate to fresh E to SE winds W of the Bahamas.
Otherwise, winds will increase to fresh to strong at night along
the N coast of Hispaniola through the middle of next  week.
