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 
0515 UTC.

...ITCZ/MONSOON TROUGH...

The Monsoon Trough extends from the African coast near 08N13W to 
05N16W. The Intertropical Convergence Zone extends from 05N16W 
to the Equator near 44W to the coast of South America near 
01S47W. Scattered moderate convection is from 00N to 05N between 
22W and 44W. 

...DISCUSSION...

GULF OF MEXICO...

Weak high pressure of 1023 mb remains centered over the 
northeastern Gulf near 29N84W, supporting fair conditions and 
light to gentle winds over the northeastern Gulf. A cold front has
entered the northwestern Gulf and extends from 30N94W to 27N98W. 
Moderate to fresh northerly winds are north of the front. 
Scattered showers and isolated thunderstorms are within 180 nm 
southeast of the front. A thermal surface trough extends from 
22N95W to 18N94W. Scattered showers and isolated thunderstorms 
associated with this trough are confined south of 25N between 90W 
and 96W. Other than the winds mentioned behind the front and over
the NE Gulf, mainly moderate to fresh easterly winds cover the 
Gulf basin. 

CARIBBEAN SEA...

The pressure gradient between high pressure north of the region
and climatological low pressure over Colombia has been supporting
fresh to strong east to northeast winds over the south Central 
Caribbean for the past several days. Winds near the coast of 
Colombia have been pulsing to near gale each night. Moderate to 
fresh east to northeast winds dominate the remainder of the 
Caribbean. Dry air and subsidence from aloft is inhibiting any 
deep convection across the basin. The only notable precipitation 
is associated with patches of trade wind showers propagating 
across the Caribbean, as well as showers along the coast of 
Central America. Little change is expected over the next 24 hours.

...HISPANIOLA...

Scattered showers in the trade wind flow will continue to affect
the windward locations of the island through Friday. 
  
ATLANTIC OCEAN...

Several surface troughs cover the SW N Atlantic tonight. One
trough extends from 24N76W to 21N76W. Scattered showers are within
120 nm of the trough axis. Another trough extends from 27N68W to
24N70W. This trough has fractured off of a third trough that
extends from 31N63W to 28N67W. The pair of troughs support a 
broad area of showers and isolated thunderstorms within 120 nm of 
either side of a line from 30N60W to 25N74W. A fourth trough 
extends from 27N58W to 22N61W. No significant convection is noted 
with this trough. A 1029 mb area of High pressure centered near 
28N34W dominates the remainder of the central and eastern 
Atlantic with fresh to strong trades covering much of the tropical
central Atlantic. These winds support seas of 9 to 12 ft.
