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

imagery, weather observations, radar and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through 
2300 UTC.


Atlantic Gale warning...A strong cold front will move off the NE 
Florida coast Tuesday evening. Low pressure will develop along 
the front north-northeast of the Bahamas Wednesday night and 
Thursday, followed by strong northerly winds to gale force. The 
front and low pressure will drift slowly eastward through Fri.

Please refer to the lastest Atlantic High Seas Forecast, under

The monsoon trough extends from the coast of Liberia near 06N10W 
to 02N23W. The ITCZ continues from 02N23W south of the equator 
at 25W. Scattered moderate rain showers are noted from 01N-06N 
between 09W-23W.


Weak surface ridging prevails across the basin, anchored by high 
pressure across the northern Gulf. This is producing gentle to 
moderate anticyclonic winds across the majority of the basin. No 
significant showers are noted. Cloud cover is increasing over 
the N Gulf ahead of a cold front poised to reach the coast of 
Texas and Louisiana tonight. Scattered moderate showers are 
along this front. The cold front will move into the northern 
Gulf tonight. Fresh northerly winds will follow the front as it 
sweeps southward, exiting the basin late Wed. Expect moderate to 
fresh southerly return flow in the NW Gulf by late week as high 
pressure builds over the Carolinas north of the front.

CARIBBEAN SEA...  A surface trough is analyzed south of Cuba 
along 80W based on surface observations. Random isolated showers 
are noted over the northern Caribbean. Scatterometer data shows 
moderate to fresh trades over much of the eastern and central 
Caribbean, with strong winds south of 13N near the coast of 

High pressure north of the area will support fresh to strong 
trade winds off Colombia into Wednesday. The winds will diminish 
later in the week as the high shifts east ahead of a cold front. 
The front will move into the northwest Caribbean late Wed, then 
stall and weaken from eastern Cuba to eastern Honduras through 


A cold front extends from 32N40W to 28N49W to 27N58W, and 
continues as a weakening stationary front to 27N60W. Scattered 
showers are within 60 nm of the front between 50W-60W. A surface 
trough extends north of Haiti from 20N72W from 25N69W. Scattered 
showers and isolated thunderstorms are seen from 22N-27N between 
65W-73W, including the waters east of the Bahamas. Scatterometer 
data shows moderate to fresh NE winds within 150 nm north of the 
front between 50W-70W. Over the eastern Atlantic, an occluded 
1004 mb low is near 28N17W, with a cold front extending along 
the coast of Africa. Scattered showers are within 120 nm NE of 
the low center.
