Tropical Weather Discussion for North America, Central America
Gulf of Mexico, 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 0955 UTC.

...SPECIAL FEATURES...

Gale Warning East of 35W: Meteo-France has issued a GALE WARNING
for the Canarias Offshore Zone. The forecast calls for N to NE
winds to Force 8 on the Beaufort Wind Scale, with severe gusts
between the Canary Islands through at least 28/0000 UTC. These
winds are producing rough seas.

For more information, please see the latest HIGH SEAS
FORECAST issued by Meteo-France at website: https://wwmiws.wmo.int/index.php/metareas/affiches/2

Central and Eastern Atlantic Significant Swell Event: A robust
high pressure system over the Azores supports fresh to near gale-
force trade winds and rough to very rough seas across the eastern
tropical Atlantic Ocean. These wind waves are mixing with a
decaying swell in the area. The rough to very rough seas will
spread westward over the next few days, peaking around 14 ft
Sat night to Sun. Seas will diminish by midweek.

Please read the latest NWS High Seas Forecast issued by the
National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more information.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic through the coast of Sierra
Leone near 07N12W to 04N17W. The ITCZ extends from 04N17W to
04S37W. Scattered moderate to isolated strong convection is
observed south of 08N and east of 27W.

GULF OF MEXICO...

A broad subtropical ridge over the central Atlantic extends into
the Gulf of Mexico, supporting mainly moderate southerly winds
across the basin. Seas in these waters are 4-7 ft.

For the forecast, moderate southerly return flow in the Gulf will
gradually diminish this morning ahead of a cold front approaching
the NW Gulf. This front will reach the basin this morning, slowly
sink southward across the northern half of the Gulf through Sat
night and gradually dissipate. High pressure N of the Gulf will
build back across the basin Sun into early next week, supporting
moderate to fresh winds.

CARIBBEAN SEA...

A tight pressure gradient across the central Caribbean Sea sustain
fresh to strong easterly winds and rough seas. Moderate to fresh
easterly breezes and moderate seas are found in the eastern
Caribbean and Gulf of Honduras. Elsewhere, moderate or weaker
winds and slight to moderate seas prevail.

For the forecast, a broad ridge over the central Atlantic will
support fresh to strong easterly trade winds and moderate to
rough seas across the central and eastern Caribbean over the next
several days. Building ridge by the middle of next week may result
in near gale-force winds off Colombia. Rough seas in mixed swell
will prevail in the tropical N Atlantic through early next week.
Elsewhere, mainly moderate to fresh winds will prevail.

ATLANTIC OCEAN...

A Gale Warning is in effect E of 35W, and a Significant Swell
Event continues to affect the waters over the central and
eastern Atlantic. Please, see the Special Features section above for
more information.

A robust 1035 mb high pressure system over the Azores extends to
the Bahamas. Moderate to fresh southerly winds and moderate seas
are found west of 75W. The tight pressure gradient between the
aforementioned ridge and lower pressures in the deep tropics and
western Africa result in fresh to near gale-force easterly winds
and rough seas over much of the central and eastern Atlantic.
Elsewhere, moderate or weaker winds and moderate seas are prevalent.

For the forecast west of 55W, rough seas prevail over the SE
waters. A weak front will shift off the SE U.S. coast early Sat
and move slowly southeastward and weaken across the waters W of
65W through Sun night before dissipating. Another cold front will
enter the northern waters early next week and gradually shift
southeastward and weaken. Fresh to strong easterly winds and rough
seas are forecast behind the front Mon night through Tue night
north of 27N. The subtropical ridge will build by the middle of
next week, resulting in moderate to fresh winds and rough seas
over much of the basin.
