Tropical Weather Discussion for North America, Central America
Gulf of America, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through 
2315 UTC.

...TROPICAL WAVES...

A tropical wave is analyzed along 19W, south of 20N, moving W at
10 to 15 kt. No convection is noted with this feature at this
time. 

A tropical wave is along 34N, south of 20N, moving W at around 10
to 15 kt. Scattered showers are noted along the wave axis and S 
of 12N. 

A tropical wave is along 64W, south of 20N, moving W at around 10
to 15 kt. Scattered showers are in the vicinity of the wave axis 
between 57W and 69W.

A tropical wave is over the central Caribbean with axis along 77W,
and extends from eastern Cuba to near western Colombia. No 
significant convection is associated with this wave at this time.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 19N16W and continues 
southwestward to 06N43W. The ITCZ extends from 06N43W to 10N58W. 
Aside from the convection described in the tropical wave section
above, no activity is noted at this time.
 
...GULF OF AMERICA...

A weak ridge continues to dominate the Gulf region, anchored by a
1015 mb high centered near 26N88W. Light to gentle winds prevail
across most of the basin, except gentle to moderate winds over 
the Bay of Campeche likely due to the pressure gradient between 
the ridge and a surface trough. Seas are generally 1 to 3 ft. 
Scattered showers and thunderstorms are noted in the periphery of
the high pressure, mainly affecting the land areas and nearshore
waters. 

For the forecast, weak pressure gradient will support light to
gentle winds and slight seas over much of the waters into late
next week. Winds will pulse to fresh with moderate seas off 
western Yucatan during the evenings due to a diurnal surface 
trough moving west off the peninsula each night.

...CARIBBEAN SEA...

The pressure gradient between high pressure to the north and the
Colombian low is maintaining fresh trades and 5 to 7 ft seas 
offshore Colombia, and in the Gulf of Venezuela. Similar wind 
speeds are also noted in the Gulf of Honduras. Gentle to moderate
winds and slight to moderate seas prevail elsewhere. 

For the forecast, the pressure gradient will continue supporting 
fresh to locally strong trades along with moderate seas over the 
central Caribbean through the weekend. This gradient will tighten
starting Mon, leading to a broader area of strong, locally near- 
gale force, winds and rough seas, early next week. Elsewhere, 
moderate or weaker winds and slight to moderate seas will prevail 
through the middle of next week. 
 
...ATLANTIC OCEAN...

A surface trough extends from near 30N78W to 25N81W. Scattered 
showers and thunderstorms are associated with this feature. 
Another trough is analyzed along 72W from 21N to 28N with no
dominates the remainder of the Atlantic, centered near 26N36W. 
Under this weather pattern, moderate or weaker winds and moderate 
seas prevail. 

For the forecast west of 55W, high pressure will generally 
prevail across the area into the middle of next week, supporting 
moderate or weaker winds and moderate seas. A weak cold front will
approach the northern waters then stall along 31N for the first 
part of next week.
