GULF OF MEXICO...

Surface high pressure anchored off the Carolinas extends a ridge
SW across the northern Gulf waters and provides gentle to moderate
E to SE winds and a gentle breeze basin-wide. Middle to upper
level dry air subsidence support fair weather conditions across
most of the basin, except for scattered showers in the Bay of
Campeche being supported by shallow moisture.

For the forecast, a cold front will enter the NW Gulf on Mon
supporting scattered showers and thunderstorms across the basin as
it reaches from Cape San Blas, Florida to Corpus Christi, Texas
Mon night, from Fort Myers, Florida SW to Veracruz, Mexico
offshore waters Tue night and then exit the basin on Thu. Fresh to
near gale force winds following the front will increase to gale
force winds along the E Mexico offshore waters Tue afternoon
through Wed evening. Fresh to strong northerly winds in the Bay of
Campeche are forecast to diminish to moderate to fresh speeds on
Thu.

CARIBBEAN SEA...

Please see the tropical waves section for information about the
tropical wave in the W Caribbean.



For the forecast, gentle to moderate winds and slight to moderate
seas will persist across most areas of the Caribbean through
tonight and diminish to mainly light to gentle wind speeds Mon
into Tue. Locally fresh winds in the south-central Caribbean and
the Gulf of Honduras will continue through tonight. Moderate winds
are forecast for the eastern and central Caribbean Tue night into
Thu night as two tropical waves move across the region. Otherwise,
a cold front is forecast to reach the Yucatan Channel Thu afternoon
along with moderate to fresh northerly winds and a fresh breeze
with moderate waves.

ATLANTIC OCEAN...

A weak cold front extends from around 31N67W to Nassau in the
Bahamas.

For the forecast west of 55W, the cold front will slide east
through today, and move E of the area Mon night before
dissipating. Another cold front will move offshore the SE U.S. Tue
morning, reach from Bermuda to the central Bahamas Wed evening
and then stall Thu before weakening further Thu night. Moderate to
fresh southerly winds are forecast ahead of the front to the N
and NE of the Bahamas Mon night through Wed night while fresh to
strong northerly winds are forecast behind the front Wed through
