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 0000 UTC surface analysis and satellite imagery through 
0500 UTC.

...TROPICAL WAVES...

A tropical wave is along 23W from 13N southward, moving westward 
at 5-10 kt. Scattered moderate convection, enhanced by the Monsoon
Trough and nearby ITCZ, is from 00N to 05N between 20W and 27W. 

A tropical wave is analyzed along 51W, south of 12N, moving 
westward at around 10 kt. Scattered showers are noted near the
wave axis.

A tropical wave in the western Caribbean is near 81W, south of 
15N and into the Eastern Pacific region to near 05N. This wave is
nearly stationary, with surface and upper air data from San Andres
Island indicating the wave remains east of the island. Scattered
showers and tstorms are along the coasts of Panama and Costa Rica.
 
...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 12N17W and continues 
southwestward to 03N23W. The ITCZ extends from 03N23W to 01N45W, 
east of a tropical wave. Outside of the convection related to the 
tropical waves, scattered moderate convection is within 120 nm 
on either side of the ITCZ.

GULF OF AMERICA...

Scattered moderate to strong convection has entered the NW Gulf 
waters mainly N of 26N and W of 88W. Elsewhere, the subtropical 
Atlantic ridge extends across Florida and much of the central and 
eastern Gulf waters. Satellite scatterometer data indicates gentle
to moderate SE winds across the basin, except for fresh to strong
E winds pulsing offshore the Yucatan Peninsula and through the
Straits of Florida. Seas across the basin are analyzed at 2-4 ft.

For the forecast, high pressure extending from the western 
Atlantic to the northern Gulf will change little through late Mon,
then weaken for the remainder of the week. 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 tonight through Tue as a 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.
Numerous showers and thunderstorms over the NW and north-central 
Gulf producing frequent lightning with gusty winds will continue 
to reduce visibility into early Sun. Otherwise, increasing 
moisture over the southeastern Gulf beginning around the middle 
portion of the upcoming week should lead to increasing chances for
unsettled weather in that part of the Gulf. Mariners are urged to
keep up with the latest forecast. 

CARIBBEAN SEA...

The pressure gradient between high pressure N of the region and
the Colombian Low supports fresh to strong trades in the central 
Caribbean as well as the Gulf of Honduras. Elsewhere, satellite 
scatterometer data indicates moderate to fresh trades across the 
basin. Satellite altimeter data supports an analysis of 4-7 ft 
seas across much of the Caribbean, while areas near the north
coast of Colombia are seeing seas of 7-9 ft prevail. Scattered 
moderate convection is ongoing over the waters near Cuba and 
Hispaniola.

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 well into the upcoming week bringing rough seas 
across those waters. Fresh to strong trades will pulse each 
evening over the Gulf of Honduras through the period. Fresh trades
elsewhere across the basin will begin to increase in coverage 
starting early next week as N Atlantic high pressure begins to 
shift southeastward tightening the pressure gradient. 

ATLANTIC OCEAN...

High pressure dominates the Atlantic waters, providing for
moderate to fresh trades and 4-7 ft seas across much of the 
basin. Winds are locally strong along the northern shore of
Hispaniola. Some isolated to scattered moderate convection is
moving offshore the SE US and into the western Atlantic.

For the forecast west of 55W, high pressure will continue to 
dominate most of the forecast region 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 evening into Mon before stalling near
27N, 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 initially stronger Atlantic 
high pressure begins to shift east-southeastward tightening the 
pressure gradient. The high pressure will then begin to weaken Wed
allowing for the tight gradient to slacken leading to diminishing
trades. Expect for increasing moisture along with unsettled 
weather conditions for the far western portion of the area 
beginning around the middle portion of the upcoming week.
