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 E to W ridge extends W-SW across the northern coastal waters
to over the Tx coastal bend. A surface high will develop along
the ridge, over the NE gulf waters late this afternoon. The high
will shift W-NW along the ridge to over the MS Delta late Sun,
effectively re-orientating the ridge SE to Fl Bay where it will
meander through mid week. An inverted trough will develop over
the Yucatan Peninsula during the late afternoons into the early
evening hours, and move W-NW during the night hours, and
dissipate over the SW Gulf by late each morning. Expect a
moderate to locally fresh NE-E-E wind shift along the trough. An
inverted trough will set up from near BRO Tx to the western Bay
of Campeche late Sun, and then meander through mid week. Expect
light northerly winds to SW of the trough. Otherwise, light
winds forecast near the surface high and along the ridge axis,
and light to moderate return flow elsewhere.

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

A tropical wave along 67W will continue W across the central
Caribbean through tonight accompanied by a slight fresh NE-E
wind shift. A second tropical wave will pass 55W today, and
enter the E Caribbean on Sun night, accompanied by SCT RW/ISOL
RW. The pressure gradient is supporting a small area of strong
NE-E trades along the NW coast of Colombia, and along the
southern tip of Hispaniola. The gradient will tighten as the
tropical waves move into Central Caribbean on Sun, with the area
of strong trades, and seas to 11 ft, currently along Colombia
expanding N across the waters from 11N-16N between 70W-79W on
Sun night and Mon. Guidance is hinting at a broad area of low
pressure developing over the SW Caribbean by mid week, with the
strong trades then building W between 13N-16N to the Caribbean
coast of Nicaragua as the northern extension of the waves move
W-NW into Central America.

..SW N ATLANTIC INCLUDING THE BAHAMAS...

A surface high is centered just s of Bermuda with a ridge
extending W to the Port of Jacksonville, Fl. Fresh southerly
winds, and 3-5 ft seas, are observed N of the ridge. The high
will shift NE of the area on Sun, with a ridge extending SW from
31N60W to Port Canaveral, Fl. The ridge will retract E on Sun
night as a weak cold front, preceded by moderate southerly
winds, moves off the SE CONUS. The weak front will stall briefly
from 31N79W to 29N80W on Mon evening, and then move E again late
Mon night, reaching from 31N73W to Ft. Pierce Fl on Tue, then
stall from Bermuda to the NW Bahamas on Wed into Thu. Expect
moderate to locally fresh northerly winds behind the front.

Moderate to fresh easterly trades expected S of the ridge,
except increasing to a strong breeze along the N coast of
Hispaniola and the Atlc approach to the Windward Passage during
the late afternoons into early evenings.
