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 strong cold front extends from the Florida panhandle to near
Tampico Mexico. The front will reach from northern Florida to
near Veracruz Mexico later this morning, and move south of the
basin tonight. Gale force winds are expected west of the front
along the coast of Mexico through tonight. Scatterometer data at
0400 UTC showed 33-40 kt NNW winds south of 26N west of the
front, and 25-32 kt N to NE winds elsewhere behind the front.
High pressure behind the front will slowly shift eastward along
the US gulf coast through Friday. The next cold front reaches
the Texas coast Sun night.

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

A weakening stationary front from eastern Cuba to southern
Nicaragua will dissipate later today. No recent scatterometer
data is available for confirmation of winds associated with the
front. Winds west of the front will diminish through Thu. A cold
front in the Gulf of Mexico will reach the NW Caribbean tonight,
accompanied by widespread showers, then extend from central Cuba
to Honduras Thu. Model guidance indicates active convection will
be concentrated north of Honduras through Thu morning. Fresh to
strong winds are expected behind the front through Thu night.
Fresh to locally strong E winds will pulse near the NW Colombia
coast each night through Sun night. Large NE swell will maintain
high seas in the tropical Atlc through Wed.

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

A weakening stationary front from 31N65W to eastern Cuba will
dissipate later today. A strong cold front will move off Florida
this afternoon, extend from 31N69W to eastern Cuba on Thu, then
stall SE of the Bahamas from 24N65W to the Windward Passage on
Fri. Strong high pressure behind the front will bring strong
winds and high seas NE of the Bahamas today through Thu night. An
area of low pressure deepening north of the area near Bermuda is
expected to induce an band of 30-35 kt winds in far northern
waters N of 30N on Thursday, affecting Atlc zones 113 and 115.
Marine conditions will improve Thu night through Fri night. The
frontal remnants will move west as a trough beginning on Fri.
