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 
0930 UTC.

...TROPICAL WAVES...

A tropical wave is along 19W from 13N southward, moving westward 
at around 10 kt. A cluster of moderate to isolated strong convection,
associated with the wave, covers the area from 02N to 07N between
15W and 20W. Similar convective activity is noted in the vicinity
of 06N13W. 

A tropical wave is analyzed along 46W, south of 12N, moving westward
at 10 to 15 kt. Scattered moderate convection is seen where the 
wave meets the ITCZ. 

A tropical wave is moving across the western Caribbean. Its axis 
is near 81W, south of 15N and into the Eastern Pacific region to 
near 05N, moving westward at around 10 kt. Convection is limited 
over the SW Caribbean.
 
...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 14N17W and continues 
southwestward to 03N25W. The ITCZ extends from 03N25W to 02.5N45W.
Outside of the convection related to the tropical waves, scattered
moderate convection is observed S of 04N between 23W and 35W.

...GULF OF AMERICA...

The Atlantic ridge extends across Florida into the Gulf region.
This system supports gentle to moderate E to SE winds, with the
exception of moderate to fresh NE to E winds to the N and W of the
Yucatan Peninsula. Seas are 3 to 4 ft with these winds, and 1 to 3
ft elsewhere. Scattered showers and thunderstorms are between the
western Florida Panhandle and SE Louisiana, including nearby waters.

For the forecast, high pressure extending from the western Atlantic
to the northern Gulf will change little through late Mon, then 
weaken into midweek. The related pressure gradient will maintain a
gentle to moderate east to southeast wind flow through early Sun,
except for light to gentle southeast winds W of about 94W Sat 
night through Tue as a weak trough develops off the Texas coast. 
Winds then generally become southeast at gentle to moderate speeds
across the basin through midweek, with slight to moderate seas, 
with the exception of fresh to strong winds pulsing off NW Yucatan
from the late afternoons and into the night time hours due to 
local effects associated with a thermal trough. Scattered showers 
and thunderstorms are expected near the above mentioned trough. 

...CARIBBEAN SEA...

The pressure gradient between high pressure N of the region and
the Colombia Low supports fresh to strong trades in the south-
central Caribbean, where seas are 7 to 9 ft. Another area of fresh
to strong trade winds is noted, per scatterometer data, over the 
eastern Caribbean, particularly from 14N to 17.5N between 60W and 
64W with seas of 5 to 7 ft. Moderate to fresh winds dominate the
remainder of the east and central portions of the basin as well as
the Gulf of Honduras with seas of 4 to 6 ft. Gentle to moderate 
winds and 3 to 5 ft seas prevail elsewhere, except in the lee of
Cuba where slight seas are noted. A few showers and thunderstorms
are currently affecting parts of Cuba, the area between Cuba and 
Jamaica, and Haiti, including adjacent waters. Pockets of low- 
level moisture, embedded in the trade wind flow, are affecting the
remainder of the region generating isolated to scattered passing 
showers. 

For the forecast, the pressure gradient between high pressure north
of the area and relatively lower pressures in northern South 
America will support fresh to strong trades over the south-central
Caribbean into early next week creating rough seas over these 
waters. Fresh to strong trades will also pulse each evening over 
the Gulf of Honduras. Mostly moderate trades elsewhere across the 
basin will begin to increase in coverage starting early next week 
as stronger Atlantic high pressure begins to shift southeastward 
tightening the pressure gradient. 

...ATLANTIC OCEAN...

A surface trough, remnants of an old frontal boundary, is analyzed
from 31N34W to 22N56W. Mainly low clouds are near the trough axis.  
High pressure of 1026 mb centered E of Bermuda near 32N59W dominates
the remainder of the forecast region. Under this weather pattern,
fresh to strong northerly winds and seas of 5 to 7 ft are observed
between the Canary Islands. Similar wind speeds are blowing across
the Cabo Verde Islands and regional waters, where seas are in the
6 to 8 ft range. Fresh to locally strong trades and moderate seas
dominate the remainder of the tropical Atlantic. A recent scatterometer
satellite pass show that winds are pulsing to strong force off northern
Hispaniola creating moderate to locally rough seas. Elsewhere, a gentle
to moderate anticyclonic flow is noted with moderate seas.

For the forecast west of 55W, high pressure will continue to dominate
most of the forecast region this weekend into early next week. Fresh
to strong trades will pulse north of Hispaniola during the afternoons
and evenings going into early next week. The western part of a backdoor
cold front will push south across the eastern portion of the area from
Sun afternoon into Mon before stalling near 26N, then begin to weaken,
dissipating on Tue. Fresh to strong northeast winds along with moderate
to rough seas will follow the front, subsiding late Tue. Elsewhere,
trades are forecast to increase over most of the western half of the
area starting Mon, including the waters between Cuba and the Bahamas
as well as the entrance to the Windward Passage as stronger Atlantic
high pressure begins to shift southeastward tightening the pressure
gradient.
