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 trough along 94W south of 24N will move west of the of the
area tonight. Fresh to strong southeast winds will follow in
behind the trough. Scattered showers and thunderstorms along and
in the vicinity of this trough will continue through tonight, and
possibly linger behind on Fri. Otherwise, relatively weak high
pressure will remain elsewhere across the area maintaining gentle
to moderate winds across the region through the period./.

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

Fresh to strong east to southeast winds will develop over the
Gulf of Honduras tonight into early Fri, then diminish to mainly
moderate to fresh speeds through the rest of the period. Fresh
to strong northeast to east winds will continue over the
south-central Caribbean through Mon night while expanding in
coverage. These winds will reach the Hispaniola adjacent waters
Sat night through Mon due to the tightening of the gradient in
the wake of the next tropical wave to pass across the region. A
tropical wave, with axis near 69W will move across Hispaniola
tonight and early Fri, and across the western Caribbean Fri
through Sun afternoon..

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

Favorable upper-level conditions in combination with a middle
level trough S of 28N near 78W and a surface trough near 78W
continue to support numerous showers and thunderstorms over much
of the central and northwestern Bahamas. This activity has become
better organized since yesterday. Additional slow development of
this system is possible during the next several days while it
moves northwestward toward the Florida peninsula, and then turns
northeastward off the southeastern coast of the United States.
The shower and thunderstorm is expected to contain strong gusty
winds and produce rough seas.

The pressure gradient between the surface trough and high
pressure across the remainder forecast waters will lead to the
continuation of moderate to locally fresh winds across the region
during the entire period.
