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...

Dissipating front is meandering from near Cape Coral to 25N91W
to the central Bay of Campeche and has drifted S across the S Fl
Peninsula and SE waters today. Strong NW winds assumed to be
occurring off of Veracruz will diminish this afternoon and fall
to below 20 kt tonight with seas gradually subsiding there.
Sufficient pres gradient will continue across the NE waters
today for strong NE winds and seas 5-8 ft there. Strong high pres
moving toward the eastern seaboard will maintain the pres
gradient across the NE and N central waters through Fri to
maintain fresh to locally strong E winds there. Next cold front
expected to sink across NW Gulf on Sun.

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

Broad low pres continues across SW Carib while strong ridge
persists across E central Atlc. A pair of tropical waves moving
across the E Carib today will maintain fresh E to SE winds E of
70W and very active weather, spreading across the NE Carib and
islands next 36-48 hrs. The strong ridge across the Atlc is
producing strong trades across the tropical N Atlc waters where
seas are 8-10 ft and will build W with and behind the 2 waves
during the next few days to freshen winds and build seas into the
8-11 ft range through Fri both inside the Carib E of 80W and
across tropical N Atlc waters. This general pattern to persist
into next week.

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

A broad surface trough continues between 66W and 72W to the SE of
a stalled front from 31N70W to SE FL. Front has drifted SE across
the FL coastal waters this morning and allowed for more wind and
seas than anticipated yesterday. Ft Pierce buoy fluctuating 7-8
ft past several hours and some of this wind swell reaching into
Miami area past few hours. Strong NE winds continue N of the
stalled boundary where seas are 8-12 ft. The front is expected
to move slowly SE and gradually merge with trough next 48 hrs,
becoming quasi-stationary along a position from 30N66W to the NW
Bahamas to the upper Fl Keys. Models develop a sfc low along
front late Thu early Fri just to the N of area and move it NE
while intensifying, and allowing high pres to build against
frontal remnants and freshen NE winds across waters W of 75W into
the weekend.
