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 
1717 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough axis enters the Atlantic near 08N13.5W, and 
continues southwestward to 07N16W, where it transitions to the 
ITCZ to 02N31W to 02N36W and to near 01.5N46.5W. Numerous 
moderate to isolated strong convection is noted from 01N to 07N
between 22W and 41W. Scattered moderate convection is seen from 
05S to 01N between 25W and 36W. Similar convection is found from
the Equator to 05N between 10W to 22W. 

...GULF OF AMERICA...

A trough is analyzed over the western Gulf. The stalled frontal 
boundary that extends from western Cuba to inland the Yucatan 
Peninsula has dissipated. A trough is now analyzed in the same
area. Otherwise, high pressure prevails across the Gulf. Moderate
northeast winds are concentrated over the southeastern Gulf. Seas
of around 6 ft in residual NE swell are over these waters. Light 
to gentle anticyclonic winds are present over the remainder of the
basin, except offshore the Texas coast, where moderate south to 
southwest winds are present. Seas are 2 to 5 ft across the rest 
of the of the Gulf, except in the NE Gulf where seas are 3 ft or 
less.

For the forecast, a weak cold front will quickly push across the 
E Gulf tonight into tomorrow before dissipating by Fri. Conditions
across the entire Gulf will be quiescent for next few days as 
subtle high pressure prevails. Looking ahead, a strong cold front 
should reach the N waters on Sun or Sun night with building winds 
and seas behind the front.

...CARIBBEAN SEA...

A stationary front stretches southwestward from the Great Bahama
Bank to western Cuba, where it transition to a surface trough that
extends to the Yucatan Channel into the Yucatan Peninsula. 
Isolated weak showers are possible near the trough. A trough is 
analyzed over the NE part of the basin. The latest scatterometer 
satellite data passes indicate fresh to strong trade winds present
over south-central Caribbean waters while moderate to fresh trade
winds are elsewhere east of about 80W. Seas are 6 to 8 ft with 
the fresh to strong trade winds, 5 to 7 ft elsewhere over the 
central Caribbean and 4 to 6 ft elsewhere east of 80W. Light and 
variable winds are west of 80W along with seas of 2 to 4 ft in 
southeast swell, except for higher seas of 4 to 6 ft in a north to
northeast swell between the western tip of Cuba and the northeast
part of the Yucatan Peninsula.

For the forecast, a moderate pressure gradient between the 
Bermuda- Azores High and the Colombian Low will continue to 
produce widespread fresh to strong trades over the central 
Caribbean for the next several days. Similarly, trades over the 
tropical North Atlantic will generally be fresh to strong with 
seas to 11 ft in large E swell through the weekend. Some of this 
large swell will also funnel through the Atlantic passages in the 
Lesser Antilles.

...ATLANTIC OCEAN...

A cold front extends from the north-central Atlantic southwestward 
to 31N48W and to 26N73W, where it continues as a stationary front
to the central Bahamas and to western Cuba. Moderate SW winds and
seas 8 to 11 ft are found along the front. satellite imagery 
reveals a large area of scattered moderate to isolated strong 
convection along and north of the frontal boundary between 60W and
74W. Elsewhere, a 1025 mb high pressure near 27N38W is the 
dominate feature for the central and eastern Atlantic areas. Its 
associated pressure gradient is generally providing for gentle NE 
to E winds. Seas of 8 to 10 ft in long- period north swell is 
mixing with an east swell component south of 23N and east of the 
Lesser Antilles, where fresh to locally strong trade winds are 
quite expansive in coverage. Gentle to moderate winds are over the
remainder of the Atlantic basin along with seas of 5 to 7 ft.

For the forecast, the aforementioned frontal boundary will 
dissipate late tonight. Fresh to strong SW to W winds will develop
north of the Bahamas tonight ahead of our next cold front. The 
new front should emerge off of the Florida/Georgia coast late 
tonight and extend from near 31N75W to the Florida Straits 
tomorrow morning, moving to 31N60W to the Turks and Caicos Fri 
morning, and dissipating in our NE waters from 31N55W to 27N60W 
Sat morning. Winds north of 27N both ahead and behind the cold 
front will be fresh to strong on Thu and Fri. Additionally, 8-10 
ft seas due to mixed SE and N swell will impact the waters south 
of 25N east of 65W tomorrow and extending through the weekend. 
Winds will improve across forecast waters Fri night through the 
weekend.
