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 coast of west Africa near 
10N14W and continues to 05N17W. The Intertropical Convergence 
Zone extends from 05N17W to the coast of South America near 
04S38W. Scattered moderate convection was noted from 03N-03S 
between 15W-40W. 

...DISCUSSION...

GULF OF MEXICO... 

A diffluent flow aloft over the western portion of the basin 
supports cloudiness with a few showers mainly west of 90W.
Scatterometer data depicts gentle to moderate easterly winds west
of 90W while light to gentle winds prevail over the eastern half
of Gulf. Southeast return flow is forecast to increase over the 
northwest Gulf fueling scattered strong to severe thunderstorms 
over the extreme NW Gulf and along the Upper Texas and Louisiana 
coasts by late Sunday. 

CARIBBEAN SEA...

Upper-level anticyclonic flow dominated the entire basin with an 
area of strong subsidence extending from Honduras across the 
north-central Caribbean then east-southeastward to the northern 
Leeward Islands. Mid to upper-level moisture was noted across 
Cuba extending over the Bahamas. At the surface, gentle to
moderate trades were noted across the Caribbean except locally 
moderate to fresh winds within 90 NM of the coast of Colombia.  
Expect little change in general weather conditions over the next 
24 hours.

...HISPANIOLA...

Strong subsidence was noted over the island at this time. Little 
change in the overall pattern is expected through the remainder of
the weekend. 

ATLANTIC OCEAN...

A surface trough extends across the west Atlantic from 31N66W to
28N73W. To the east, a 1022 mb surface high is centered near
25N49W. The remains of a frontal system were analyzed as a 
surface trough that extends from 32N32W to 26N37W. No significant 
convection is related to any of these features. Expect during the 
next 24 hours for the troughs to dissipate. Surface ridging will 
prevail across the basin.
