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 1040 UTC.
...SPECIAL FEATURES...
Caribbean Gale Warning: A strong ridge north of the area will
continue to support fresh to strong trade winds across the south-
central Caribbean. Winds will pulse to gale-force each night
offshore of Colombia through early next week. Peak seas with
these winds are expected to be at or near 12 ft.
...MONSOON TROUGH/ITCZ...
The monsoon trough passes through the coastal plains of Liberia
near 06N10W to 04N15W. The ITCZ continues from 04N15W to 02S37W.
Scattered moderate convection and thunderstorms are ongoing from
08S to 04N between 21W and 44W.
...GULF OF MEXICO...
Surface ridging associated with a 1021 mb high pressure centered
off Cedar Key, Florida near 29N83W extends basin-wide. A surface
trough prevails over the eastern Bay of Campeche producing
isolated showers, and supporting moderate winds. A tighter
pressure gradient over the SE Gulf is also supporting moderate E
to SE winds through the Florida Straits and the Yucatan Channel.
Seas across the basin are slight, except moderate over NW Cuba
adjacent waters.
For the forecast, fresh to locally strong NE to E winds will
occur each afternoon and evening offshore of the Yucatan Peninsula
and through the Florida Straits as a surface trough develops over
the Yucatan Peninsula daily and moves westward towards Tampico
and Veracruz. Otherwise, high pressure over the remainder of the
basin will support gentle to moderate winds and slight to moderate
seas through early next week.
...CARIBBEAN SEA...
See the Special Feature Section for details on an ongoing Gale
Warning off the coast of Colombia.
A broad subtropical ridge north of the area is supporting fresh
to strong NE to E winds across the central and southwest
Caribbean, the lee of Cuba and Hispaniola, and the Windward
Passage. Moderate to fresh NE to E winds prevail elsewhere along
with moderate seas.
For the forecast, winds will pulse to gale force each night and
early morning offshore of Colombia as a strong pressure gradient
prevails between high pressure over the western Atlantic and low
pressure over northwestern Colombia. Locally rough seas will be
possible near and to the west of the strongest winds. Fresh E to
NE trade winds and rough seas are expected across the remainder
southwestern and central Caribbean through early next week, with
winds pulsing to strong speeds through the Windward Passage, in
the Gulf of Venezuela, downwind of Hispaniola and in the lee of
Cuba. Moderate to locally fresh NE winds will occur across the
remainder of the basin. East swell developing today will lead to
rough seas near the Windward and Leeward Islands and their
passages into the eastern Caribbean Sea through Mon night.
...ATLANTIC OCEAN...
Surface ridging prevails over the western and eastern subtropical
Atlantic waters while the tail of a cold front continues to move
eastward over the central Atlantic. The front extends from 31N52W
to 27N61W. A surface trough is ahead of the front from 30N49W to
25N57W with isolated showers. Moderate to fresh NE to E winds are
ongoing behind the front between 55W to 72W with mainly moderate
seas. Winds of same magnitude and direction are also ongoing over
the subtropical waters E of 30W where rough seas to 9 ft are
present. Otherwise, moderate to fresh NE to E winds are across the
tropical Atlantic with locally strong NE winds just west of the
Cape Verde Islands. Seas over the tropics are 8 to 9 ft.
For the forecast west of 55W, moderate to fresh E trade winds
will prevail south of 25N through Mon night. An increasing
pressure gradient due to building high pressure in the western
Atlantic will support moderate to fresh NE winds north of 25N and
east of 70W through Fri morning. Winds will diminish in this
region thereafter, with gentle to moderate winds continuing into
early next week. Developing east swell will lead to rough seas NE
of the Leeward Islands and NE of Puerto Rico this evening through Sun.

1215 UTC Mon Feb 10 2025
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 0945 UTC.
...SPECIAL FEATURES...
Caribbean Gale Warning:
A tight pressure gradient between a 1026 mb high pressure oriented
along 31N and low pressure centered across NW Colombia continues
to support strong winds that pulse to gale force during the
overnight hours offshore Barranquilla, Colombia. These conditions
will prevail through Thursday night. Seas will peak at 11 to 13 ft
near the highest winds.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic Ocean near the coastal
border of Guinea and Sierra Leone, then runs southwestward to
03N23W. An ITCZ continues west-southwestward from 03N23W across
00N30W to 00N45W. Scattered moderate convection is seen south of
the monsoon trough from 01N to 05N between 10W and 23W, and near
the ITCZ from the Equator to 04N between 23W and 45W.
...GULF OF MEXICO...
A surface ridge extends southwestward from a 1023 mb high over
the Florida Big Bend area to south of Tampico, Mexico. Light to
gentle winds and seas of 1 to 2 ft are present across the northern
Gulf. Moderate with locally fresh NE to E winds and 3 to 5 ft
seas are found across the southern Gulf. Patchy fog is reducing
visibility over coastal waters within 90 nm of the U.S. shore.
For the forecast, high pressure centered NE of the area will
dominate much of the week, but gradually move east, allowing a
cold front to enter the NW Gulf late this week. Southerly winds
will increase ahead of this front, with some locally strong winds
possible in the central Gulf.
...CARIBBEAN SEA...
Please read the Special Feature Section about a Gale Warning in
effect offshore Colombia.
A broad surface ridge with an axis roughly along 31N is sustaining
a trade-wind pattern across the basin. Fresh to strong ENE winds
and 7 to 10 ft seas are noted in the central and eastern basin, as
well as in the Windward Passage. Mainly moderate E winds with seas
of 4 to 7 ft dominate the western basin.
For the forecast, fresh E to NE trade winds and rough seas are
expected across the southwestern and central Caribbean into the
weekend, with winds pulsing to strong speeds through the Windward
Passage, in the Gulf of Venezuela, and S of Hispaniola. Moderate
to locally fresh NE winds will prevail across the remainder of the
basin. East swell will bring rough seas near the Windward and
Leeward Islands and their passages into the eastern Caribbean Sea
through the week.
...ATLANTIC OCEAN...
A cold front has devolved into a surface trough in the eastern
Atlantic that stretches from 31N19W to 28N22W this morning. A
broad high pressure, anchored by a 1026 mb center near 33N39W,
extending W along 31N, is dominating most of the basin, supporting
light to gentle winds and seas of 4 to 7 ft for waters N of 26N.
To the south, an expansive trade-wind regime dominates, with
mainly fresh ENE winds and seas of 6 to 9 ft.
For the forecast W of 55W, moderate to fresh trade winds will
prevail south of 25N into the weekend. Elsewhere, gentle to
moderate winds will prevail through late week. East swell will
bring rough seas NE of the Leeward Islands and NE of Puerto Rico

1215 UTC Tue Feb 11 2025
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 1000 UTC.
...SPECIAL FEATURES...
Caribbean Gale Warning:
A tight pressure gradient between high pressure centered N of the
basin and lower pressure over northwestern Colombia will continue
to support strong to near-gale winds at the south- central
Caribbean through Friday. These winds are expected to peak at
gale- force during the nighttime and early morning hours offshore
of Barranquilla, Colombia. Seas will peak at 11 to 13 ft near the
highest winds.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic Ocean through the coast of
Sierra Leone near Freetown, then extends southwestward to 03N16W.
An ITCZ meanders westward from 03N16W to 00N42W. Scattered
moderate to isolated strong convection is noted up to 180 nm along
either side of the ITCZ.
...GULF OF MEXICO...
A stationary front extends from near Pensacola, Florida, to New
Orleans, Louisiana, to near Galveston Bay. Convection associated
with this front has diminished early this morning, but patchy fog
is restricting visibility within about 90 nm S of the boundary.
Elsewhere, ridging from a 1022 mb high pressure center N of the
Bahamas is leading to mainly moderate SE winds and 2 to 4 ft seas
throughout the basin.
For the forecast, a cold front will enter the NW Gulf Wed night,
then stall from the Bay of Campeche to near the Florida Big Bend
Fri. Southerly winds will increase ahead of the front in the
central Gulf Wed. Strong to near gale force winds are expected
behind the front, possibly reaching minimal gale force off
Tampico, Mexico briefly Thu evening.
...CARIBBEAN SEA...
Please refer to the Special Feature section for information on a
Gale Warning offshore Colombia.
The Atlantic Ridge oriented along 28N is sustaining a trade-wind
regime across the Caribbean Basin. Outside the Gale Warning area,
strong ENE winds and seas of 9 to 11 ft are evident in the central
basin. Fresh with locally strong NE to ENE winds and 6 to 9 ft
seas are noted across eastern basin, as well as the Windward and
Mona passages. Moderate to fresh ENE winds and seas at 3 to 6 ft
dominate the western basin.
For the forecast, fresh E to NE trade winds and rough seas are
expected across the remainder southwestern and central Caribbean
into the weekend, with winds pulsing to strong speeds through the
Windward Passage, in the Gulf of Venezuela, and S of Hispaniola.
As the high pressure to the north builds southeast for the latter
half of the week, strong winds and rough seas will expand to
include much of the eastern Caribbean.
...ATLANTIC OCEAN...
A surface ridge extends west-southwestward from the northeastern
Atlantic across 31N37W and a 1025 mb high near 28N56W to a 1022
mb high north of the Bahamas. Light to gentle winds with 3 to 6 ft
seas in mixed moderate swells are found north of 25N. Farther
south, mainly fresh ENE winds and seas of 7 to 10 ft exist.
For the forecast W of 55W, fresh to locally strong trade winds
will prevail south of 25N through the weekend. Gentle to moderate
winds will prevail N of 25N until Fri, when a cold front will
slide south of 30N to the W of 70W, bringing fresh to strong NE
winds behind it. Easterly swell and waves from the aforementioned
trade winds will lead to rough seas S of 22N through the weekend.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Wed Feb 12 2025
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 1000 UTC.
...SPECIAL FEATURES...
Caribbean Gale Warning: The tight pressure gradient between a 1027
mb high pressure system near Bermuda and lower pressures in
northern Colombia is resulting in pulsing winds to gale force
each night and early morning offshore of Colombia. This is
expected to continue through early Fri morning. Rough to very
rough seas are forecast with these winds, peaking near 14 ft
during the highest winds. Winds and seas will diminish somewhat
during the weekend.
...MONSOON TROUGH/ITCZ...
The monsoon trough reaches the eastern Atlantic through the coast
of Guinea-Bissau near 12N16W and continues southwestward to
03N24W. The ITCZ extends from 03N24W to 00N37W and to 00N50W.
Scattered moderate convection is observed south of 05N and
between 22W and 42W.
...GULF OF MEXICO...
A frontal boundary over the far NW Gulf is now retreating N as a
warm front, noted early this morning from SE Louisiana to the
upper Texas coast. Convection associated with this feature has
moved well inland. Elsewhere, a ridge over the western Atlantic
continues to influence the weather conditions in the Gulf of
Mexico. The pressure gradient between this ridge and lower
pressures in Mexico and southern Texas support fresh southerly
winds over much of the basin. These winds are sustaining seas of 3-6 ft.
For the forecast, a cold front will enter the NW Gulf late tonight,
then stall from just N of Tampa Bay to near Veracruz, Mexico by
Fri night. Strong S winds are expected ahead of this front into
tonight, mainly in the central Gulf. Strong to near gale force
winds are expected behind the front in the western Gulf. Looking
ahead, the next cold front is expected to enter the NW Gulf early
Sun and move SE across the basin by Mon evening. Strong to near
gale force N winds will also follow this front in the western Gulf.
...CARIBBEAN SEA...
A Gale Warning remains in effect off the coast of Colombia. Please,
read the Special Feature Section for details.
The basin remains under the dominion of a broad subtropical ridge
positioned over the central and western Atlantic. The pressure
gradient between this ridge and the Colombian low forces fresh to
strong winds across the central and eastern Caribbean, including
the Windward Passage. Seas in these waters are 6-10 ft. Moderate
to locally fresh easterly winds and moderate seas are noted in the
rest of the Caribbean.
For the forecast, the pressure gradient between a high pressure
ridge across the western Atlantic along 28N and low pressure over
northwestern Colombia will support strong trade winds across the
central Caribbean pulsing to gale force each night and early
morning near the coast of NW Colombia through Thu night. Rough to
very rough seas are expected near and to the west of the highest
winds. Fresh E to NE trade winds and rough seas are expected
across the remainder of southwestern and central Caribbean into
the weekend, with winds pulsing to strong speeds through the
Windward Passage, in the Gulf of Venezuela, and S of Hispaniola.
Atlantic high pressure will move to near 55W early Thu through
Fri, briefly shifting the zone of strong trade winds and rough
seas across the eastern Caribbean and Tropical North Atlantic
waters. Looking ahead, Atlantic high pressure will begin to shift
eastward Mon and Tue, leading to decreasing winds and seas across the basin.
...ATLANTIC OCEAN...
A weak cold front is sagging just S of 30N from 50W to 70W.
Otherwise, the basin is dominated by a broad subtropical ridge.
Fresh to locally strong easterly trade winds are present south of
25N and west of 55W. Seas in the area described are 6-9 ft.
Moderate to fresh southerly winds and moderate seas are noted west
of 75W and north of 25N.
The subtropical ridge is also forcing fresh to strong NE-E trade
winds south of 23N and between Africa and the Lesser Antilles.
Wave heights in these waters are in the 7 to 10 ft range. The
strongest winds and highest seas are found west of 50W and south
of 20N. Elsewhere in the basin, moderate or weaker winds and
moderate seas are prevalent.
For the forecast W of 55W, fresh to locally strong trade winds
will prevail south of 25N through the weekend as the Atlantic
ridge persists along 28N-29N. Associated easterly swell will also
lead to rough seas S of 22N through the weekend. Gentle to
moderate winds will prevail N of 25N until Thu, when a cold front
will move into the NW waters, south of 30N and to the W of 70W,
bringing fresh to strong NE winds behind it. The front is expected
to move eastward into the weekend, and stall E to W along 26N on
Sat. The next front will exit the SE U.S. Sun night and reach from
near Bermuda to the NW Bahamas Mon afternoon.

A 1022 mb low pressure area is centered over the NW Gulf, with
associated cold front extending to near Tampico, Mexico. Fresh to
strong winds are west of the front as well as NE of the low. Strong
to near gale force winds, and seas of 8-11 ft, are off the coast
of Veracruz, Mexico. Elsewhere W of 90W, seas are in the 7-10 ft
range. Moderate to fresh winds, and seas of 4-7 ft, prevail E of
90W.
For the forecast, the low will track NE through early Sun night,
then quickly E to SE toward southern Florida on Mon with the cold
front trailing from the low as it moves across the basin. Fresh to
strong winds are expected around the low pressure while moderate
to fresh winds are expected behind the boundary. Weak high
pressure will settle over the central Gulf Tue through Wed night
in its wake with tranquil marine conditions across the basin.
...CARIBBEAN SEA...
A Gale Warning is in effect off the coast of Colombia. Please,
refer to the Special Features section above for more details.
A dissipating frontal boundary is over the NW Caribbean. Moderate
to fresh winds, and seas of 5-7 ft, are W of the front. Fresh to
strong winds are in the lee of Cuba. Aside from the gale force
winds off Colombia, fresh to strong winds are over the south
central Caribbean, with moderate to fresh winds over the north
central Caribbean. Gentle to moderate winds prevail over the
eastern Caribbean. Seas of 8-10 ft are in the south central
Caribbean, with 4-6 ft seas elsewhere.
For the forecast, moderate to fresh trade winds and moderate seas
will prevail over most of the central and eastern Caribbean
through Mon night, except for strong to near gale-force winds and
rough seas offshore of Colombia and within and near the Gulf of
Venezuela. Winds off Colombia will pulse to gale-force tonight. A
stationary front over the NW Caribbean will dissipate today.
Strong high pressure building in the wake of the front will bring
fresh to strong NE winds in the Lee of Cuba and the Windward
Passage through early Sun.
...ATLANTIC OCEAN...
A cold front extends from near 31N51W southwestward to the
southern Bahamas, then becomes stationary to central Cuba. Fresh
to strong winds, and seas of 8-11 ft are N of 29N E of the front
to 45W. Fresh to strong winds are S of 23N W of the front with
gentle to moderate winds elsewhere W of the front. Seas of 8-14 ft
are W of the front to 75W, and 4-7 ft W of 75W. A surface ridge
extends from 31N28W SW to near 24N59W, with light to gentle winds
along the ridge axis. Fresh to strong winds are west of the coast
of Africa to just W of the Cabo Verde Islands. Moderate winds
prevail elsewhere. Seas of 8-12 ft prevail over much of the waters
E of 50W, and 5-8 ft elsewhere.
For the forecast west of 55W, the front will weaken as it reaches
from near 26N55W to 24N60W tonight before dissipating. Strong
high pressure in the wake of the front will lead to fresh to
strong northeast winds south of 25N and west of the front,
including the Straits of Florida through tonight. Conditions will
improve Sun into early Mon. Broad low pressure from the Gulf will
quickly approach South Florida Mon, and track NE to north 31N by
late Tue night with a trailing cold front across the western part
of the area. By late Wed night, fresh to strong winds will be
confined to the NE part of the area.
