Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0430 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal sections of
Guinea-Bissau near 12N17W, to 05N19W.
The ITCZ continues from 05N19W, 03N25W, to 01N30W, to the
Equator along 39W. Precipitation: scattered moderate to strong
is within 90 nm of the coast of Suriname. Scattered moderate to
isolated strong is within 30 nm of the NW coast of French
Guiana. Scattered moderate to widely scattered strong is from
01N to 03N between 41W and 43W. Isolated moderate to locally
strong is from 06N southward from 40W eastward.

GULF OF MEXICO...

Broad surface anticyclonic wind flow spans the Gulf of Mexico. A
surface ridge extends from Louisiana into the SW corner of the
Gulf of Mexico.

Fresh to strong NE winds are in the south central and the
southeastern Gulf of Mexico.

Fresh to strong winds and moderate seas in the southeastern Gulf
of Mexico will diminish gradually and subside by Sunday. High
pressure will continue to extend across the basin through the
middle of next week. Fresh to strong winds will pulse W-NW of
the Yucatan Peninsula at night through early next week.

CARIBBEAN SEA...

A stationary front passes through the northern coastal areas of
Haiti, to the eastern sections of Jamaica, to the eastern
coastal sections of Honduras, to south central Honduras.
Precipitation:  rainshowers are possible from the stationary
front northward and northwestward.

A surface trough is along 11N73W in northern Colombia, to the
Colombia/Panama border, beyond 07N80W, into the eastern Pacific
Ocean. Precipitation: scattered moderate to strong is within a
30 nm radius of 06N75W, about 180 nm to the SE of the surface
trough. Scattered moderate to strong also is in Colombia from
04N southward between 71W and 75W. Please refer to the forecasts
and the weather bulletins from your local meteorological offices
for more details.

Broken to overcast low level clouds, and isolated moderate
rainshowers, cover the rest of the Caribbean Sea. The clouds and
isolated moderate precipitation are moving with the
surface-to-low level wind flow.

The current stationary front stretches from the Windward Passage
to Jamaica, continuing to near the Honduras-Nicaragua border.
The front is expected to dissipate gradually through the
remainder of the weekend. Fresh to strong winds and building
seas to the west of the front will persist in the Lee of Cuba
and across the approach to the Windward Passage through early
next week. High pressure in the Atlantic Ocean will support
fresh to strong trade winds in the south central Caribbean Sea
through early next week, with the highest winds near the
Colombia coast.

ATLANTIC OCEAN...

A cold front passes through 32N59W, to 30N60W 21N70W, to the
northern coastal sections of Haiti.
Precipitation: scattered moderate to isolated strong is from 29N
northward between 50W and 56W. Isolated to widely scattered
moderate and locally strong is elsewhere from 24N northward
between 50W and the cold front. Rainshowers are possible from
20N to 24N between 55W and the cold front.

A cold front passes through 32N29W, to 30N30W, 27N34W, and to
26N40W. A surface trough continues from 26N40W, to 28N44W and
30N47W. Precipitation: isolated moderate rainshowers are from
20N northward between 23W and 50W.

The current cold front from 26N65W to the Windward Passage will
move eastward slowly, in the southeastern waters, and across
Hispaniola. Fresh to strong NW to N winds, and building seas,
are expected through Sunday, behind the cold front. Fresh to
strong winds will continue near the Windward Passage through
Monday. High pressure will settle across the region early next
week, with more tranquil marine conditions forecast.
