Corrected Atlantic Ocean section

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 
1730 UTC.

...SPECIAL FEATURES...

East Atlantic Gale Warning: Meteo-France has issued a Gale 
Warning along with rough to very rough seas for their AGADIR 
Marine Zone through 23/0600 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 axis enters the Atlantic along the coast of
Guinea near 10N14W, and continues southwestward to 03N20W, where
it transitions to the ITCZ to 01N30W and to south of the Equator
reaching to near the coast of Brazil at 02S43W. Scattered 
moderate to isolated strong convection is seen within 120 nm north
of the ITCZ between 20W-28W. Scattered moderate convection is 
within 120 nm north of the ITCZ between 28W-31W, and also from
01N to 03N between 31W-38W.

...GULF OF AMERICA...
 
Broad high pressure ridging extends west-southwestward from the 
western Atlantic to across the eastern and central Gulf. The
related gradient is providing for moderate to fresh east-southeast
winds across the basin along with seas of 3 to 5 ft, except for 
slightly lowers seas of 2 to 4 ft in the north-central and NE Gulf 
sections. No significant convection is present over the basin.

For the forecast, high pressure centered NE of the area will 
bring mainly moderate SE winds and relatively tranquil marine 
conditions to the northern half of the basin through the week. The
southern Gulf will experience fresh east to southeast winds, 
pulsing to strong off the NW Yucatan Peninsula each night as a 
diurnal trough affects the waters. 

...CARIBBEAN SEA... 

The pressure gradient between subtropical ridging to the north
and relatively lower pressures in South America and the southern
Caribbean is inducing fresh to strong trades over most of
the central Caribbean as well as south of the Greater Antilles 
and adjacent passages. Seas in these areas are 6 to 9 ft. 
Elsewhere in the western Caribbean, moderate to fresh trades 
prevail along with seas of 4 to 7 ft, except for higher seas of 
6 to 8 ft north of 18N between 76W and 80W. In the eastern part 
of the basin, mainly gentle trades, with slight to moderate seas 
prevail.

For the forecast, high pressure north of the basin will support 
pulsing fresh to strong trades over the central and western 
Caribbean sections into tonight. The high pressure will shift 
eastward, which will weaken the pressure gradient and diminish 
winds Wed afternoon through late week. Moderate northerly swell 
impacting the Mona passage will gradually subside into early this
evening. Gentle to moderate trades along with slight to moderate 
seas will then prevail into the upcoming weekend.

...ATLANTIC OCEAN...Corrected 

Please see the Special Features section above for information on a
Gale Warning issued in the far eastern Atlantic.

A stationary front stretches from near 31N52W to 30N60W and to 
near 27N58W. This stationary front will soon begin to weaken,
then gradually dissipate tonight into Wed. South of this front, a
persistent surface trough stretches from near 30N58W to a 1011 mb 
low near 25N60W, and continues southward to 15N58W. The low is 
co-located with a large upper-level low. satellite imagery shows 
a rather extensive area of mostly light to moderate rain over an
area that covers the waters from 25N to 28N between 58W and 62W.
To the southeast of this area, numerous moderate convection is
occurring from 24N to 27N between 52W and 58W. Latest partial 
scatterometer satellite data passes indicate fresh to strong 
northeast to east winds west of the trough and low to near 67W 
and north of 20N. These winds are due to a tight pressure 
gradient between persistent high pressure off the U.S. eastern 
seaboard and the trough and low. Seas with these winds are 7 to 
10 ft. Farther to the west, waters north of 25N that are closer 
to the high are experiencing gentle winds and slight to moderate 
seas, where waters south of 25N are generally under fresh 
northeast to east winds and seas of 5 to 7 ft, including the 
Greater Antilles and adjacent passages. 

Across the central and eastern tropical Atlantic, a 1028 mb high 
pressure center is well north of the area. Broad ridging 
associated with this feature controls the weather pattern over 
these areas of the Atlantic allowing for moderate to fresh 
trades to exits along with seas of 5 to 7 ft. East of 35W and 
north of the Cabo Verde Islands, seas of 8 to 10 ft are present 
due to northeast swell that has been generated from higher winds 
that are northeast of the discussion area.

For the forecast west of 55W, the pressure gradient between 
the aforementioned low and trough and the high pressure that is 
centered well north of the area will continue to support fresh 
to strong northeast winds and rough seas over Atlantic waters to 
the east of about 70W and north of 23N into Wed. The trough will 
gradually weaken later during the week as it moves slowly 
westward. This will lead to a weakening of the pressure gradient 
that will result in improving marine conditions for the end of 
the week.
