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...

Areas of dense fog will be possible, especially close to shore
under continued deep and moist SE flow. A weak cold front will
drift into the Texas coastal waters through the evening before
stalling and moving back inland into early Thu, with isolated
thunderstorms possible ahead of it. Strong high pressure across
the W Atlc will maintain a ridge extending W across the Gulf
coast states to produce fresh return flow across most of the
basin, except strong winds through the Straits of Florida and
across central portion of the Gulf. Seas will occasionally build
to 8 ft in and near the area of higher winds, with mainly 4-7 ft
seas elsewhere and otherwise. The ridging will weaken by the end
of the week through the weekend, allowing for winds and seas to
diminish and subside somewhat. A weak cold front will drift
into the far NW waters Sat night and stall there through Sun
night.

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

Strong high pres across the NW Atlc will dominate the region as
it settles across the Bermuda area through the end of the week.
Fresh to strong tradewinds will prevail across the Caribbean and
Tropical N Atlc waters through Thu, with nocturnal winds pulsing
to gale force winds off of Colombia. Winds will likely peak
overnight tonight, to around 40 kt, with large seas up to 12-16
ft NW of the coast of Colombia. Fresh to strong winds will
continue through the approach to the Windward Passage, as well as
in the Gulf of Honduras through Thu night, and all other Atlantic
passages. High pres will weaken through the weekend, leading to
diminishing winds and seas across the basin.

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

W Atlc ridge will persist along 33N-34N through Thu then drift
SW and slowly weaken by the end of the week through the weekend.
Gentle to moderate winds will prevail N of 25N with fresh to
strong winds S of 25N through Thu. NNE swell will move through
waters E of 65W through Fri night. As the ridging weakens, the
winds and seas will significantly diminish and subside with
little change likely into early next week.
