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 few showers and thunderstorms are active across the SE Gulf on
the NE side of an upper low centered over the central Gulf near
26N89W. An associated surface trough is analyzed from SE
Florida to western Cuba. This weather will move with the upper
low as it tracks WNW toward the Texas coast through mid week,
while winds will increase to fresh in the SE Gulf through the
Straits of Florida in the wake of the surface trough through the
early part of the week. Meanwhile the remnants of Harvey in the
Caribbean will move across the Yucatan peninsula and may emerge
into the far SW Gulf/Bay of Campeche Wed bringing increasing
winds and seas along with active convection, possibly re-
developing into a tropical cyclone as it moves NNW toward NE
Mexico through late week. Elsewhere, weak ridging will persist
across the northern Gulf or along the northern coast, maintaining
light to gentle winds and slight seas.

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

The remnants of former tropical cyclone Harvey are centered over
the central Caribbean between Grand Cayman Island and central
Panama. The convection remains disorganized over eastern Honduras
well to the west of the poorly low level center. Along with
scattered thunderstorms, Harvey is accompanied by fresh to
strong winds and seas of 8 to 10 ft on its northern periphery as
it continues to move WNW through the northwest Caribbean through
early Tue, with a medium chance of re-developing into a tropical
cyclone. Interests in Central America should continue to monitor
http://hurricanes.gov for the latest on this area.

A broad tropical wave is associated withe remnant low of Harvey,
between central Cuba and central Panama. A 02 UTC scatterometer
pass indicated strong eastern winds between Jamaica and eastern
Cuba in the wake of the tropical wave. Moderate to fresh
easterly trade winds persist elsewhere. Winds will pulse to
fresh to strong in the S central Caribbean late Wed night through
the end of the week as the pressure gradient tightens across
that area. Another tropical wave will pass 55W Tue, enter the
eastern Caribbean Wed, then cross the central Caribbean through
late in the week.

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

Scattered showers and thunderstorms are noted east of the central
Bahamas associated with a trough reaching from central Hispaniola
northward along 72W to 25N. An area of fresh winds and seas of 8
to 9 ft also accompany the trough as it moves west toward the
central and southern Bahamas through mid week. Meanwhile,
ridging extends from E to W along 30N. The ridge will lift
northward as the trough continues to progress to the W, reaching
the southern Bahamas and Turks/Caicos late tonight. Weak ridging
will build across the area through midweek with fairly tranquil
marine conditions expected basin-wide.
