...GULF OF MEXICO...

A cold front extending from the Mississippi Delta to Veracruz
Mexico will reach from the Port of Tampa to Yucatan Channel this
evening, and continue east passing through the Bahama Channel on
Sat night. Strong to near gale force southerly flow and
scattered and thunderstorms will precede the front across the
eastern Gulf of Mexico. Strong to near gale force northwesterly
flow will continue west of the front through sunrise Sat, with
an embedded area of minimal gale conditions across the west-
central waters early this afternoon. Moderate west flow expected
on Sat evening as the seas subside to less than 8 ft. The
gradient will continue to relax on Mon with light northerly
winds expected. Moderate return flow will set up across the
northwest waters on Tue, with broad low pressure developing over
the southwest gulf.

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

Fresh to strong trade winds will prevail across the Caribbean
generally east of 80W through early Sun, with nocturnal pulses
to near gale force off the northwest coast of Colombia. A cold
front will enter the Yucatan Channel this evening, stall and
then gradually dissipate over the NW Caribbean on Sat through
Mon. Strong north winds are forecast west of the front across
the Gulf of Honduras late tonight through late Sun. Large north
swell will reach the Leewards on Sat, and spread south through
the northeast Atlantic passages during the upcoming weekend, and
subside from the north early next week.

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

A warm front extending east to west along 25N will accelerate to
the north tonight and gradually wash out across the northeast
portion on Sat, with strong east to southeast flow ahead of the
front. Strong to near gale force southerly return flow will
continue elsewhere north of the Bahamas ahead of a cold front
that will reach from 31N77W to the Bahama Channel Sat evening,
reach from 31N72W to central Cuba on Sun, and extend from
Bermuda to east Cuba on Mon. The front will stall across the
tropical waters north of Antilles by the middle of next week,
with the remnants lifting back north late next week.
