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 extends from SW Florida to the NW Yucatan peninsula
to near 18N93W in the far SW Gulf. Strong winds follow the front,
especially over the far NW Gulf where reinforcing cold air is
seeping into the region. The reinforcement will maintain strong
winds and seas to 10 ft over mainly the western Gulf into
Wednesday. Winds and seas diminish thereafter as the front slips
to the south of the area and high pressure builds over the
northern Gulf. Fresh return flow will begin over the NW Gulf by
early Fri, ahead of another front moving into the NW Gulf late
Fri. The front will reach from the western Florida Panhandle to
the far SW Gulf by midday Sat, with winds funneling along the
coast of Mexico reaching possibly gale force and seas building 10
to 13 ft. The front will pass SE of the region Sun, interacting
with a low pressure area moving ahead of the front from the NW
Caribbean across western and central Cuba. Winds and seas will 
gradually diminish across the Gulf through late Sun as high 
pressure builds over the region.
     
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W... 

Broad low pressure is becoming a little better organized over the
far SW Caribbean near 11N82W. The low pressure is expected to
evolve gradually as it moves into the NW Caribbean through Sat,
but then will move more NE through western and central Cuba ahead
of cold front moving across the Gulf of Mexico. The front will
dig through the Yucatan Channel and into the NW Gulf late Sat and
Sun in the wake of the low pressure, followed by strong northerly
winds and seas to 8 ft, mainly near the Yucatan Channel.
Elsewhere moderate trades will persist. 

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

A cold front is moving off the coast of NE Florida, currently
reaching from 31N78W to near Cape Canaveral. The front will reach
from 31N77W to the northern Keys early Wed, from 31N70W to 
eastern Cuba by early Thu, before stalling and weakening from 
Bermuda to central Cuba through Fri and Sat. Fresh to strong NW 
winds behind the front will diminish Wed, leaving a fairly weak 
pressure pattern along with gentle breezes over the region 
through the remainder of the week. Looking ahead, another front 
will move off the coast of NE Florida by early Sun, followed by 
strong NW winds and seas to 8 ft.
