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 slowing cold front extends from Tampa Bay Florida to 26N90W
then becomes stationary to extreme northeast Mexico. The front
will stall east to west along 26N late this evening. Remnants of
the front will lift north as a warm front on Sat ahead of a
second cold front reaching the Texas coast around sunrise on Sun
preceded by a line of thunderstorms. This second cold front will
reach from the Mississippi Delta to the Bay of Campeche on Sun
night, from the Florida Big bend to the Yucatan Peninsula on Mon
night, then drift southeast on Tue and finally southeast of the
gulf waters late Wed.

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

Atlantic high pressure will maintain fresh to locally strong
trades across the south-central Caribbean through early Sun.
Strong nocturnal trades are then expected to resume on Sun night
along the north coast of the South America. Northeast swell
currently across the tropical waters east of the Leewards will
gradually subside through late Sat. A weakening cold front will
pass southeast through the Yucatan Basin on Tue night, and wash
out across the northwest Caribbean during the middle of next
week.

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

A cold front extending southwest from 31N72W to Port Canaveral
Florida will reach from Bermuda to south Florida this evening,
then stall east to west along 26N on Sat night. Remnants of this
front will lift north on Sun with near gale force southeast flow
developing north of the Bahamas on Mon to the east of a surface
low shifting east across the southeast United States. The
surface low will move northeast along the Georgia and South
Carolina coasts on Tue, and drag a cold front across the
northwest waters during the middle of next week.
