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 cold front moving slowly east across the northwest gulf waters
will accelerate east this evening reaching from the Florida Big
Bend area to northeast Mexico late tonight, then stall from
southwest Florida to northeast Mexico on Fri.  Remnants of the
front will lift north as a warm front on Sat ahead of a second
cold front reaching the Texas coast late Sat night. This second,
convective cold front will reach from the Mississippi Delta to
the Bay of Campeche late Sun, and from Tampa Bay to the Yucatan
Peninsula late Mon. The then weakening cold front will move
southeast of the area late Tue.

...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 Sat.
Strong nocturnal trades are then expected to resume Sat night
along the north coast of the South America. Northeast swell
currently across the tropical waters east of the Leewards will
subside on Sat. A weakening cold front will pass southeast
through the Yucatan Basin on Tue, and wash out across the
northwest Caribbean during the middle of next week.

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

Weakening remnants of a stationary front from 28N65W to 25N74W
will drift west and gradually dissipate through Fri. A cold
front moving off the northeast Florida coast this afternoon will
reach from Bermuda to south Florida by late Fri, then stall from
26N65W to the Straits of Florida late Sat. Remnants of this
front will lift north on Sun with minimal gale force southeast
flow developing north of the Bahamas on Sun night all to the
east of a surface low shifting east across the southeast United
States. The surface low will move northeast along the Georgia an
South Carolina coasts on Tue, and drag a cold front across the
northwest waters during the middle of next week.
