...SPECIAL FEATURES...

Atlantic Ocean Gale-Force Wind Warning:

The strong cold front that already moved through the Gulf of 
Mexico, is moving through the SW N Atlantic Ocean now. The cold 
front stretches from 31N76W to the Bahamas and to central Cuba 
near 23N79W. The wind speeds are gale-force N of 27N behind the 
front. Expect the sea heights to range from 16 feet to 20 feet, 
from tonight through Saturday. The wind speeds will diminish to 
less than gale-force tonight. The wind speeds will become gentle 
to moderate by Sunday. The comparatively higher sea heights will 
persist to the E of the Bahamas through early next week. 
Precipitation: 
widely scattered moderate to isolated strong is from 24N 
northward from 60W westward.

Please, read the latest Offshore Forecast, that is issued by the 
National Hurricane Center, at the website, 
https://www.nhc.noaa.gov/text/MIAOFFNT3.shtml, for more details.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal border sections of 
Sierra Leone and Liberia, to 04N26W. The ITCZ is not 
distinguishable at the moment. Precipitation: scattered moderate 
to strong is within 75 nm to the north of the monsoon trough, 
and within 150 nm to the south of the monsoon trough, between 
12W and 18W. Isolated moderate is elsewhere from 10N southward 
from 60W eastward.

...GULF OF MEXICO...

Please, read the SPECIAL FEATURES section, for details about a 
gale-force wind warning.

The strong cold front of the last 24 hours has moved through the 
entire Gulf of Mexico. Broad surface anticyclonic wind flow spans
the whole area. A surface ridge passes through the Deep South of 
Texas, to the coastal plains of Mexico, to the Isthmus of 
Tehuantepec of southern Mexico. The broken to overcast skies with 
the front gradually are becoming clearing skies more and more with
time. Strong to near-gale force northerly winds follow the front,
except for offshore waters of Tampico and Veracruz that are 
experiencing gale conditions with seas to 13 feet.

The strong cold front has exited the basin. Gale force winds 
continue along the coasts of Tampico and Veracruz, through Sat 
morning. The central and eastern Gulf of Mexico can expect 
frequent gusts to gale force through Sat morning with rough 
seas. Seas are forecast to build to 12-15 ft with the strongest 
winds. Marine conditions will improve by Sun. Then, expect 
increasing southerly return flow in the western Gulf, from Sun 
night into Mon, ahead of a low pressure system that is forecast 
to move across the NW Gulf on Tue.

...CARIBBEAN SEA...

A cold front passes through central Cuba, beyond the SE part of 
the Yucatan Peninsula, to the eastern sections of the Isthmus of 
Tehuantepec of southern Mexico. Precipitation: broken to 
overcast multilayered clouds and rainshowers are along and to 
the north of the cold front.

Patches of shallow moisture are supporting passing rainshowers, 
that are evident throughout the area. 

Mostly fresh-to-some strong winds are within 240 nm of the 
coasts of Venezuela and Colombia between 66W and 76W. Moderate 
winds or slower are elsewhere. The sea heights range from 3 feet 
to 5 feet.

Fresh to strong winds will pulse north of Colombia tonight with 
gentle to moderate trades elsewhere. A cold front will enter the 
NW Caribbean tonight and reach eastern Cuba to the Gulf of 
Honduras by Sat morning, and from Haiti to near Cabo Gracias a 
Dios, Nicaragua by Sun morning. Fresh to strong 
northerly winds and building seas of 8-10 ft will follow the 
front with the highest seas in the Yucatan Channel. Fresh to 
locally strong winds can be expected in the Windward Passage, 
from Sun through early Tue, behind the front. 

...ATLANTIC OCEAN...

Please, read the SPECIAL FEATURES section, for details about a 
gale-force wind warning and accompanying sea heights, that are 
related to a cold front.

The sea heights range from 7 feet to 9 feet from 06N to 16N 
between 25W and 35W. The sea heights are reaching 8 feet within 
250 nm of the coast of Africa from 12N to 15N. The sea heights 
range from 4 feet to 7 feet, elsewhere, from 60W eastward. 
Strong winds are within 380 nm of the coast of Africa from 13N 
to 18N. Fresh winds are elsewhere from 11N to 20N within 500 nm 
of the coast of Africa. Fresh winds are from 05N northward 
between 24W and 40W. Mostly fresh-to-some strong winds are from 
11N southward between 40W and 50W.

A surface trough curves along 31N52W 28N56W, to a 1016 mb low 
pressure center that is near 25N57W. The surface trough 
continues from the 1016 mb low pressure center to 22N57W and to 
19N60W. Precipitation: isolated moderate to locally strong is 
from 19N northward between 47W and 61W. Isolated moderate also 
is from 10N to 19N between 50W and 60W.

Upper level cyclonic wind flow covers the Atlantic Ocean from 
15N to 28N between 40W and 50W. A surface trough is along 
46W/47W from 13N to 24N. Precipitation: isolated to widely 
scattered moderate and locally strong are from 10N to 28N 
between 35W and 50W. tween 42W and 44W. Isolated moderate is in 
the remainder of the area that is from 13N to 30N between 35W 
and 48W.

A cold front stretches from 31N76W to the Bahamas and to central 
Cuba near 23N79W. Strong winds are following the front. Gale 
force winds will develop N of 27N behind the front with seas of 
16-20 ft tonight through Sat. Winds will diminish below gale 
force by Sat night, with winds becoming gentle to moderate by 
Sun. Large seas will persist E of the Bahamas through early next 
week.
