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 extending from 25N81W to 18N92W will support strong
to near gale force winds in the SW basin and moderate to fresh
winds elsewhere. The front will move E of the basin by this
evening. A second front will enter the northern Gulf on Sat.
Strong high pressure building behind this front will support
fresh northeast winds over most of the SE Gulf by the end of the
week. These winds may reach strong speeds on Sat along with
building seas.

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

Moderate to fresh winds are expected over the central and
eastern Caribbean through Sat, and will decrease to gentle to
moderate for the remaining period. A tropical wave located over
the west-central Caribbean Sea is expected to move westward over
the next couple of days and interact with a frontal system,
producing a broad area of low pressure over the western
Caribbean Sea by Thursday night or Friday. Environmental
conditions are forecast to be conducive for some development
thereafter, and a tropical depression could form over the
weekend.

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

Moderate to fresh winds ahead and behind a cold front that
extends from 30N76W to 26N80W will prevail to the E of the
Bahamas through Thu as the front dissipates. A pair of tropical
waves will move across the eastern and central Caribbean Thu
through Sun and will support moderate to fresh winds over the SE
offshore waters, incresing to strong N of Hispaniola at night.
