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 1800 UTC surface analysis and satellite imagery through 
2305 UTC.

...SPECIAL FEATURES...

East Atlantic Gale Warning: Meteo-France has issued a Gale 
Warning along with very rough seas for their AGADIR Marine Zone, 
through 23/0000 UTC. Please see the latest HIGH SEAS FORECAST and
WARNING issued by Meteo-France at website: https://wwmiws.wmo.int
for more information.

...MONSOON TROUGH/ITCZ... 

The monsoon trough enters the Atlantic through the coast of Guinea
near 10N14W and continues to 02N21W. The ITCZ extends from 02N21W
to 02S43W. Scattered moderate convection is noted south of 07N and
east of 27W.

...GULF OF AMERICA...

A stationary front is located along the Texas coast, producing
scattered showers and isolated thunderstorms across the NW Gulf
waters. The rest of the basin is under the influence of a strong
subtropical ridge over the western Atlantic. Moderate to locally
strong easterly winds and moderate seas are found south of 26N and
east of 93W. Light to gentle winds and slight to moderate seas
prevail elsewhere.

For the forecast, a moderate pressure gradient between high pressure 
centered offshore the SE United States and lower pressure toward 
the SW Gulf will support pulsing fresh to strong SE winds over 
the SE Gulf through tonight, along with moderate seas. Conditions
will start to improve Tue as the area of high pressure moves 
further from the area and the pressure gradient weakens. One 
exception is off the NW Yucatan Peninsula where pulses of strong 
winds are expected as a diurnal trough moves into the waters. 

...CARIBBEAN SEA... 

The combination between a 1027 mb high pressure system in the 
western Atlantic and relatively lower pressure in South America is
supporting fresh to strong easterly trade winds across the central
Caribbean, lee of Cuba and Gulf of Honduras. Seas of 6-9 ft are
noted in the central Caribbean, while seas of 3-6 ft are found in
the lee of Cuba and Gulf of Honduras. Moderate or weaker winds and
slight to moderate seas are prevalent in the remainder of the
basin.

For the forecast, high pressure north of the basin will support
pulsing fresh to strong NE winds across the central and western 
Caribbean through midweek. The high will then shift eastward which
will loosen the pressure gradient and diminish winds into late 
week. Large northerly swell impacting the Mona and Anegada 
passages will gradually subside by midweek. Gentle to moderate 
winds and slight to moderate seas will then prevail through the 
weekend. 

...ATLANTIC OCEAN...

Please see the Special Features section above for information on 
gale-force winds in the far eastern Atlantic.

A surface trough extends from 31N57W to the Lesser Antilles,
producing scattered showers and isolated thunderstorms north of
20N and between 45W and 60W. The remainder of the SW North
Atlantic is dominated by a broad subtropical ridge over the
western Atlantic. The pressure gradient between this ridge and
lower pressures associated with the aforementioned trough result
in fresh to strong NE winds between a line from 31N55W to the US 
Virgin Islands and 70W. Seas in these waters are 7-11 ft. Fresh 
to strong SE winds and rough seas are present from 22N to 26N and 
between 53W and 58W. 

The remainder of the tropical Atlantic is dominated by a 1026 mb 
high pressure system centered south of the Azores. This ridge 
forces moderate to fresh easterly winds between 20W and 50W. 
Seas in the area described are 5-10 ft, with the highest seas 
near 23N21W. A tighter pressure gradient near Africa allow for 
fresh to strong N-NE winds and seas of 6-11 ft north of 11N and 
east of 20W. Elsewhere across the Atlantic, moderate or weaker 
winds and moderate seas prevail.

For the forecast west of 55W, the pressure gradient between a 
surface trough along 58W and high pressure centered just W of 
Bermuda will support fresh to strong NE winds and rough seas over 
Atlantic waters E of 70W, as well as S of 28W, including the 
Bahamas and Greater Antilles through midweek. Both the trough and 
the high pressure will then weaken, loosening the pressure 
gradient and leading to improving conditions through the end of 
the week.
