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 thermal trough will develop late each afternoon over the
Yucatan Peninsula, and shift w across the southwestern gulf
waters, generally to s of 24N between 90W and 93W, during the
overnight and early daylight hours, and gradually lose identity
along about 94W by late each morning. Expect a ne-e-se 15-20 kt
wind shift along the trough axis, except 20 to 25 kt along the n
coast of the Yucatan Peninsula this evening and on Mon evening,
with guidance hinting that these brief strong conditions will
not develop again till Fri evening. Expect seas to build briefly
to 6 ft just w of the strong winds.

A surface high will meander over the far ne gulf waters through
Thu night with fresh moderate southerly return flow over the
waters w of 88W, increasing to fresh breeze each evening, with 3
to 5 ft seas throughout the period. Light and variable winds
will surround the high center, with light to moderate
anticyclonic flow forecast e of 88W through Thu night, except
becoming a fresh breeze across the Fl Straights during the
evenings. Widespread fog observed over the nw gulf this morning
will be carried in weather grids ahead of convection.

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

Atlc high pressure will support fresh e trades, with 5-8 ft
seas, across the central Caribbean through Tue morning, with
strong nocturnal trades within about 90 nm of the nw coast of
Colombia and across the Gulf of Venezuela. The pressure gradient
will tighten on Tue, with strong e winds expanding n from the
Colombian coast to along 15N between about 70W and 77W on Wed,
and expanding further n and further w on Thu with seas building
to 11 ft near 13N75W. Strong nocturnal e to se trades forecast
across the Gulf of Honduras through Thu night. Tropical waves
over the e Caribbean and over the tropical waters e of the
Windwards, will continue westward accompanied by a moderate to
fresh ne-e-se wind shift and only a slight enhancement of
convection.

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

A weakening cold front extending sw from 31N60W to the central
Bahamas will dissipate today. A ridge will extend e to w along
27N later today where it will meander through Tue, then shift n
to along 28N on Wed and along 29N on Thu. Moderate to fresh
easterlies are expected s of 23N, except becoming a strong e
breeze along the n coast of Hispaniola during the evenings
beginning on Mon. Moderate sw flow forecast n of the ridge.
