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...

Hurricane Nate is making landfall tonight over Mississippi. The 
Hurricane will weaken to a tropical storm later this morning 
before it reaches near 32.1N 88.2W. Nate will continue to weaken 
as it moves well inland near 35.7N 85.3W by this evening. 

Large seas an strong winds associated with Nate will linger over
the northern Gulf through today. By tonight expect winds to 
diminish below 20 kt and seas to decrease to less than 8 ft. 

High pres ridging will build in the wake of Nate for the early 
part of this week with more tranquil marine conditions 
anticipated. By Tuesday night, forecast models are suggesting 
that a cold front will reach the western Gulf and cross the
western Gulf basin. High pressure building behind the front may 
produce strong winds along the Mexico coast west of 95W, 
including Vera Cruz on Wednesday. 

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

Lingering low level convergence well to the southeast of
departing Hurricane Nate and upper level diffluence is 
supporting showers and thunderstorms over the NW Caribbean this 
morning. These conditions are expected to improve through today 
as Atlantic high pressure expands westward well to the north of 
the region. As the ridging settles well to the north of the area 
early in the week, the area will be under a weak pressure 
pattern, with mainly gentle to moderate winds and seas of 3 to 5 
ft forecast to dominate the Caribbean basin and tropical Atlantic
waters through the middle of this week. 

A pair of tropical waves crossing the tropical Atlantic waters
the next few days will support showers and thunderstorms. One of 
the waves is expected to reach the Lesser Antilles Monday, and 
cross the eastern Caribbean Tuesday and Wednesday. 

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

A ridge will dominate the northern waters the next several days
supporting mainly moderate winds over the northern waters. A 
a trough along 68W/70W S of 27N continues to produce scattered 
moderate to isolated strong convection over the southeastern 
zones. A scatterometer pass this evening shows moderate to fresh
winds associated with this trough. These winds will support seas
of 6 to 7 ft as it slowly move towards the Bahamas through early
next week while weakening. Another trough will move across the 
area Tuesday night through the latter part of the week, preceded
by fresh to possibly strong NE to E winds and building seas to 8
ft.
