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 1200 UTC surface analysis and satellite imagery through 
1639 UTC.

...SPECIAL FEATURES...

Significant Rainfall over Central America: Periods of heavy rain 
will continue to affect portions of Central America, particularly
areas in Costa Rica, Nicaragua and Honduras through at least 
early Fri. Abundant tropical moisture persists over the region, 
supported by a broad cyclonic circulation and a tropical wave 
that is currently over Honduras and Nicaragua, and extends 
southward over Costa Rica. Showers and thunderstorms are 
occurring over NE Honduras, the eastern plains of Nicaragua and 
parts of Costa Rica, and western Panama. Areas of Nicaragua and 
Costa Rica are forecast to observe the highest amounts of rain 
today. Please refer to the local Weather Services in the region 
for more information.

...TROPICAL WAVES...

An eastern Atlantic tropical wave has been relocated based on
satellite imagery and wave diagnostics. The wave axis is along 
25W, south of 14N. Scattered moderate convection is depicted from 
04N to 14N between 17.5W and 28W. 

Another Atlantic tropical wave has been relocated based on
satellite imagery and wave diagnostics and is now along 40W, 
south of 15.5N. A few showers are seen near the trough axis.

A western Caribbean tropical wave is along 75W, south of 19N, 
moving westward around 25 kt. No significant convection is 
depicted at the moment in association with this wave. 

A strong tropical wave is along 84W in the western Caribbean, 
south of 19N, moving westward at 10 to 15 kt. The wave is helping
to induce convection over parts of Central America. Please, see 
the Special Features section for more details. 

...MONSOON TROUGH/ITCZ... 

The monsoon trough enters the Atlantic Ocean through the coast of
Mauritania near 19N16W and continues southwestward to 08N41.5W. 
The ITCZ extends from 08N41.5W to 05N52W. Scattered moderate to 
isolated strong convection is present from 05N to 11N between 28.5W
and 38W. 

...GULF OF AMERICA...

A ridge remains in control of the weather pattern across the Gulf
waters producing in general gentle to moderate E to SE winds over
the central Gulf with seas 3 to 5 ft. Light and variable winds 
and slight seas prevail over the NE Gulf and the western Gulf. 
Showers, with embedded thunderstorms, are observed over the SW 
Gulf, including the Veracruz area. Scattered showers and 
thunderstorms are seen elsewhere across the western Gulf. A 
deep layer trough is helping to induce this convective activity.

For the forecast, a ridge will continue to dominate the Gulf 
waters through the upcoming weekend. Fresh to locally strong NE to
E winds will pulse each evening and night over the next several 
days north of the Yucatan Peninsula and in the eastern Bay of 
Campeche due to local effects induced by a thermal trough. Gentle 
to moderate E to SE winds and slight to moderate seas can be 
expected elsewhere through Sun. 

...CARIBBEAN SEA...

Two tropical waves are moving westward across the Caribbean Sea.
Please, refer to the Tropical Waves section for more details. 

Fresh to strong trade winds prevail over most of the east and 
central Caribbean, with the strongest winds of 25 to 30 kt over 
the south-central Caribbean, offshore Colombia. Rough seas are 
within these winds. Gentle to moderate trades and moderate seas 
dominate the remainder of the basin. 

For the forecast, the pressure gradient between the Atlantic 
ridge and lower pressure in the SW Caribbean associated with the E
Pacific monsoon and the passage of tropical waves will continue 
to support fresh to strong trades across most of the central and 
SW Caribbean through Sun night. Winds are expected to reach near 
gale force off Colombia and in the Gulf of Venezuela Thu and Thu 
night. Moderate to rough seas are expected within these winds. 
Elsewhere, moderate to fresh winds and moderate seas will prevail.
Winds will increase to strong speeds over the Gulf of Honduras 
tonight through Sat night due to a tighter pressure gradient 
between the Atlantic ridge and a broad area of low pressure 
located over the eastern Pacific region, offshore of Central 
America and Southern Mexico. 

...ATLANTIC OCEAN...

A broad upper-level low, spinning just N of the NW Bahamas, is
generating scattered to numerous showers and thunderstorms over
most of the waters NW of a line from 27N54W to the SE Bahamas, 
including the area between the Bahamas and east-central Cuba and 
the Straits of Florida. The Bermuda-Azores high dominates the 
Atlantic forecast region, with a 1028 mb center located near 
33N37W. Scatterometer and altimeter data indicates moderate to 
fresh trades and moderate seas over the tropical Atlantic 
including the coast of W Africa, and between the Canary Islands. 
Fresh E to SE winds are noted N of Puerto Rico. Elsewhere, 
moderate or weaker winds and slight to moderate seas prevail. 

For the forecast west of 55W, the Bermuda High and associated 
ridge will prevail across the region through the weekend, 
supporting moderate to fresh E to SE winds and moderate seas S of 
25N. Gentle to locally moderate winds and slight to moderate seas 
are expected elsewhere. Otherwise, fresh to strong E winds will 
pulse late in the afternoons and at night N of Hispaniola through 
the weekend.
