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 0600 UTC surface analysis and satellite imagery through 
0730 UTC.

...TROPICAL WAVES...

An eastern Atlantic tropical wave is along 28W, south of 16N, and
just SW of the Cabo Verde Islands, moving westward around 10 kt. 
A few showers are observed near the wave axis.

Another eastern Atlantic tropical wave is along 37W, from the Mona
Passage south of 18N to western Venezuela, moving westward at
10-15 kt. A few showers are observed near the wave axis.

An eastern Caribbean tropical wave is along 68.5W, south of 17N, 
moving westward at 10-15 kt. A few showers are present near the
wave axis, with a large cluster of deep thunderstorms ahead of the
wave over NW Venezuela and portions of Colombia.

A western Caribbean tropical wave is along 85W, south of 18N,
extending across eastern Honduras, Nicaragua and western Costa 
Rica, into the eastern Pacific. The wave is moving westward at 
around 10 kt. A few showers near the wave axis.

...MONSOON TROUGH/ITCZ... 

The monsoon trough enters the Atlantic through the coast of
Mauritania near 18N16W and continues southwestward to 08N30W. The
ITCZ extends from 08N30W to 06N35W, then resumes W of a tropical
wave near 05N39W to the coast of Brazil at 02N51W. No significant
convection is evident along the monsoon trough or ITCZ, except
near the coast of Brazil from the Equator to the ITCZ, W of 48W.

...GULF OF AMERICA...

An upper level trough extends from the central United States 
southward across Texas and NE Mexico, and the adjacent Gulf 
waters, and is providing unstable conditions to the east of the 
trough. A few showers and isolated thunderstorms are noted in the
northern Gulf waters. At the surface, a surface trough is 
analyzed in the SW Gulf west of the Yucatan Peninsula with 
scattered thunderstorms south of 22N. The rest of the Gulf is 
mainly influenced by the western periphery of the Atlantic 
subtropical ridge, extending westward across Florida and into the 
central Gulf. The pressure gradient between the ridge and lower 
pressures in Mexico result in moderate to fresh SE winds over much
of the western and central Gulf waters. Seas in the area 
described are 3-5 ft. Elsewhere, moderate or weaker winds and 
slight seas prevail, locally 3-5 ft in the Straits of Florida. 

For the forecast, Atlantic ridging will extend westward across 
the Gulf through the next several days. Fresh northeast to east 
winds are expected each afternoon and evening north of the Yucatan
Peninsula and into the eastern Bay of Campeche as a trough 
develops daily and moves westward. Moderate to fresh southeast 
winds are forecast elsewhere in the western and south- central 
Gulf, with gentle to moderate winds across the remainder of the 
basin. 

...CARIBBEAN SEA...

The eastern portion of the eastern Pacific Ocean monsoon trough
extends from Costa Rica into the SW Caribbean through a 1010 mb
low pressure area near 11N81W to the coast of Colombia near
10.5N75W. Scattered thunderstorms are present near the low.

The pressure gradient between the subtropical Atlantic high
pressure centered just east of Bermuda and lower pressure over 
Colombia and the SW Caribbean continues to support fresh to 
locally strong easterly trade winds across the eastern and 
central Caribbean, and near the Gulf of Honduras. Seas in these 
waters are 5-9 ft. Elsewhere, moderate or weaker winds and slight
to moderate seas are prevalent, except locally fresh winds through
the Windward Passage.

For the forecast, the pressure gradient between high pressure N 
of the basin and relatively lower pressures in the Caribbean and 
in northern South America will maintain fresh to strong trades and
moderate to rough seas over most of the central and west-central 
Caribbean through the forecast period. Winds will pulse to fresh 
to strong speeds near the Gulf of Honduras during the evening and 
overnight hours, with greater coverage of these winds expected to 
begin on Mon, with passage of a tropical wave. Moderate to fresh 
winds will prevail elsewhere, except in the lee of Cuba and the SW
Caribbean where gentle to moderate winds are expected through 
early next week. Mostly fresh trades will remain over the Tropical
N Atlantic zones through early next week. Moderate to locally 
rough seas with these winds will gradually subside through 
tonight. 

...ATLANTIC OCEAN...

Please see the TROPICAL WAVES section above for information on
tropical waves present in the basin. 

The broad subtropical ridge over the central Atlantic dominates
the tropical Atlantic waters. The pressure gradient between the
ridge and lower pressures in the deep tropics support moderate to
fresh easterly winds south of 22N and west of 40W, including
through the Windward Passage. Seas in these waters are 5-8 ft. In
the eastern Atlantic, moderate to locally strong N-NE winds and 
seas of 6-9 ft are noted north of 20N and east of 20W. Elsewhere,
moderate or weaker winds and moderate seas prevail.

For the forecast west of 55W, surface ridging will be the main 
feature controlling the wind regime across the region into next 
week, keeping fairly benign marine conditions. Pulsing fresh to 
locally strong winds are expected north of Hispaniola to near 22N 
during each late afternoon and at night through early next week.
