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 1200 UTC surface analysis and satellite imagery through
1700 UTC.

...SPECIAL FEATURE...

High pressure north of the area will support fresh to strong
easterly winds across the south-central Caribbean through the
weekend, pulsing to gale-force tonight off Colombia and near-gale
force each night thereafter. Please refer to the High Seas Forecast
product under AWIPS/WMO headers FZNT02 KNHC/HSFAT2, or the
following website:

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Africa near 05N08W
to 00N15W. The ITCZ continues from 00N15W to 01N25W to the coast
of Brazil near 02S42W. Scattered moderate convection is noted
along and in the vicinity of both boundaries mainly south of 07N.

GULF OF MEXICO...

A dissipating frontal boundary was analyzed as a surface trough
that extends across the Straits of Florida from 24N81W to 23N84W.
A pair of surface troughs extend over the southwest Gulf waters
with no significant convection. The first is from 22N89W to 19N92W
while the second one is from 23N97W to 20N96W. Surface ridging
prevails across the remainder of the basin, anchored by a 1029 mb
high centered inland over western Georgia. Scatterometer data
depicts gentle to moderate anticyclonic winds across the basin.

High pressure will continue building in the wake of the front and
will prevail through the weekend. The next cold front will move
into the northwest Gulf by Sunday night.

CARIBBEAN SEA...

Gale-force winds are expected to develop tonight across the
south-central Caribbean. Refer to the section above for details.

High pres north of the area supports moderate to fresh trades
across the central Caribbean, while moderate northeasterly winds
prevail elsewhere, except near the Windward Passage at night
tonight and Thu night, where fresh to strong winds are expected.
Fresh easterly swell will build in the tropical Atlantic by the
end of the week.

ATLANTIC OCEAN...

A cold front enters the waters at 31N68W to 24N80W. Showers are
noted along the front. To the east, a surface trough extends from
28N65W to 25N66W with scattered showers mainly between 58W-65W.
Surface ridge prevails elsewhere, anchored by a 1037 mb high
centered near 39N36W.

The cold front will stall from near 30N65W to the Straits of
Florida by tonight. High pressure will build in the wake of the
front over the west Atlantic and prevail through the weekend. No
significant change is expected elsewhere.
