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 has recently exited the Gulf. Scatterometer data
shows fresh to strong NE winds in most of the forecast area. The
pressure gradient associated with trough across the SW Gulf
continues to support 25-30 kt NW winds west of the trough along
the Veracruz coast of southern Mexico. High pressure behind the
front will slowly shift eastward along the US Gulf coast through
Friday. Fresh southerly return flow will set up in the western
Gulf Fri and Sat ahead on the next cold front, forecast to reach
the Texas coast Sun night.

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

A cold front extends from W Cuba near 23N81W to the Gulf of
Honduras near 16N88W. Fresh to strong NE winds are over the
entire NW Caribbean N of 15N and W of 78W. Widespread shallow
convection is all across this area. A stationary front will
extend from NW Hispaniola to NE Nicaragua Fri. Strong winds and
widespread showers are expected behind the front. Fresh to
strong trade winds will pulse near the coast of Colombia coast
Fri night, then expand and strengthen across much of the central
Caribbean over the weekend as high pressure builds N of area in
the west-central Atlantic.

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

A cold front extends over the W Atlantic from 31N70W through the
N Bahamas to W Cuba near 23N81W. The cold front will extend from
near 31N63W to NW Hispaniola tonight, then extend from 31N57W to
22N64W to 20N73W on Friday. A band of gale force westerly winds
are currently north of 30N within 180 nm W of front. Strong
winds and high seas are expected NE of the Bahamas through early
Fri. High pressure will build east over the SW N Atlantic waters
over the weekend.
