...GULF OF MEXICO...

A weak low pressure has developed over the SE Gulf near the
northern end of a tropical wave. This system is expected to move
over the southeastern Gulf of Mexico today, the central Gulf on
Wednesday, and the northwestern Gulf on Thursday and Friday.
Increasing winds and seas are expected in association with this
system.  

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

The pressure gradient between high pressure north of the area
and low pressure over Colombia will maintain fresh to locally
strong trade winds over the south-central Caribbean this week.
Elsewhere, gentle to moderate trade winds will persist across
the region for the next several days. Expect increasing winds
and seas over the NE Caribbean toward the end of the week as
high pressure builds across the western Atlantic.  

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

A ridge north of the area will support pulses of  fresh to
locally strong winds off Hispaniola and near the entrance to the
Windward Passage for the next several nights. Winds and seas
will increase E of 65W toward the end of the week as high
pressure builds across the western Atlantic.
