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... 

1012 mb high pressure is building over the central Gulf of Mexico
this morning following a cold front that moved southeast of the
basin yesterday. Moderate to fresh southerly return flow is noted
over the far northwest Gulf off the coast of Texas, between the
high pressure and troughing over the southern Plains. These winds
will increase to fresh to strong southerly flow by Wednesday
ahead of an approaching front. The front will move off the Texas
coast late Wednesday, then make slow progress eastward, before
stalling from the north central Gulf to the central Bay of
Campeche late Thursday. The front will lift north into early
Friday ahead of a broad area of moderate to fresh southerly 
flow. Winds and seas will increase Saturday across much of the
western Gulf ahead of a deeper lower pressure moving through
Texas.

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

A weak cold front reaches from the Isle of Youth off western Cuba
to Cozumel off the eastern coast of Yucatan. The front will
dissipate through today. Relatively weak ridging north of the
area is maintaining gentle to moderate winds across the western
Caribbean. Stronger ridging over the north central Atlantic is
supporting moderate to fresh trade winds over the eastern
Caribbean and tropical north Atlantic waters west of 55W. Little
change is expected through the remainder of the week, except for
brief pulses of fresh to strong winds mainly during overnight
hours in the Gulf of Honduras and off Colombia starting Wednesday
night. Additional pulses will occur south of Hispaniola and in 
the Gulf of Venezuela Friday night into Saturday. 

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

Having moved from southeast Gulf through south Florida over the
past couple of days, deep low pressure is now north of the area
off the Carolina coast. A trailing cold front reaches from the
low pressure to western Cuba. Winds to minimal gale force ahead
of the front north of 28N have diminished, as noted in a recent 
scatterometer pass. A pre-frontal trough is noted 31N73w through
the southern Bahamas to eastern Cuba. Ship and buoy observations
farther east are still showing strong southerly winds and 8 to 
10 ft seas ahead of the trough, north of 27N between 67W and 
72W. A large cluster of showers and thunderstorms is noted within
120 nm of 24N69W. The front will continue slowly east through
late today, then dissipate through tonight. Ridging will build
across the region along 27N/28N in the wake of the front,
allowing gentle to moderate winds and slightly seas through
Saturday.
