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: A Gale Warning remains in effect for
the Canarias and Agadir Marine Zones of Meteo France. The
forecast calls for NE winds to Force 8 on the Beaufort Wind
Scale, with severe gusts between the Canary Islands through at
least 01/0000 UTC. Seas currently range from 9 to 13 ft N of 10N
and E of 30W based on a recent altimeter pass. Higher seas of 12
to 15 ft are possible just N of the Canary Islands.

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 near the Azores is maintaining fresh to
near gale-force trade winds across the eastern and central
Atlantic. Wind waves generated by these winds will continue to
generate seas of 8 to 13 ft across most of the waters between 20W
and 60W, with highest seas E of 40W. This event will persist
through early next week, while drifting SW.

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 along the coast of Guinea
near 11N14W, then extends southwestward to 05N18W. The ITCZ
continues from 05N18W to the coast of Brazil near 04S38W.
Scattered moderate convection is observed south of 06N and east of 30W.

...GULF OF MEXICO...

A stationary front extends from the Florida Big Bend region to a
1013 mb low pres near 27N87W and then to the south Texas coast. A
few showers and isolated thunderstorms are noted in the SE Gulf
waters. A weak pressure gradient dominates the Gulf, resulting in
moderate or weaker winds and slight to moderate seas.

For the forecast, the storm activity will progress southeastward
this morning and weaken. The weak front will slowly sink
southeastward and exit the basin tonight. Later, a strong high
pressure system will build west-southwestward over the area from
the N Atlantic beginning on Sun night, with the related gradient
generally supporting moderate to fresh east to southeast winds
across the Gulf. Locally strong winds will occur at night off N
Yucatan Tue and Wed.

...CARIBBEAN SEA...

A strong high pressure system centered over the central Atlantic
combines with the Colombian low to support fresh to near gale-
force trade winds over the central Caribbean. Seas are 7 to 10 ft
with these winds. Moderate to fresh trades and moderate seas
dominate the eastern Caribbean, while mainly gentle to moderate E
to SE winds with moderate seas are noted over the NW part of the
basin. Seas to 8 ft are noted across the Atlantic passages in the
Lesser Antilles.

For the forecast, an expansive subtropical ridge over the central
Atlantic will support fresh to near gale-force easterly trade winds
and moderate to rough seas across the central and eastern Caribbean
over the next several days. A tighter pressure gradient will
initiate gale-force winds off Colombia at night Mon through at least
late next week and support locally very rough seas. Fresh to strong
trades expected elsewhere across most of the central and eastern
portions of the basin. In the meantime, rough seas in mixed swell
will prevail in the tropical N Atlantic through the forecast period,
with seas to 12 ft reaching 55W Mon. Elsewhere, little change is
expected with moderate to fresh trades continuing through the period.

...ATLANTIC OCEAN...

A Gale warning is in effect E of 35W. Please, see the Special
Features section for more information.

A nearly stationary front has exited the coast off NE Florida,
supporting numerous showers and isolated thunderstorms W of 75W
and N of 27N. Meanwhile, a 1034 mb high pressure system located
near the Azores extends an extensive ridge across the entire
Atlantic forecast waters. The tight pressure gradient between the
ridge and lower pressures in the deep tropics and western Africa
result in fresh to near gale-force easterly winds and rough to
very rough seas over much of the central and eastern Atlantic.
Moderate to fresh easterly winds and rough seas are found north of
20N and between 50W and 65W. Elsewhere, moderate or weaker winds
and moderate seas are prevalent.

For the forecast west of 55W, the aforementioned front is expected
to move slowly southeastward and weaken across the waters W of
65W through Sun night before dissipating. Elsewhere, high pressure
over the central Atlantic continues to maintain control over much
of the western Atlantic while rough seas prevail over the SE
waters. Another cold front is expected to enter the northern
waters early next week and gradually shift southeastward and
weaken. Fresh to near gale-force easterly winds and rough to very
rough seas, peaking around 14 ft, are forecast behind the front
Mon through Tue night north of 27N. High pressure will build by
the middle of next week resulting in moderate to fresh winds and
rough seas over much of the basin.

1215 UTC Thu Mar 19 2026

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 1010 UTC.

...SPECIAL FEATURES...

East Atlantic Gale Warning: A gale warning is in effect, issued by Meteo-France, for the high seas zones of Irving, west of Madeira,
and Meteor until 20/00 UTC at least, with severe gusts. Please refer
to the next Special Feature for details on associated large swells.
Please refer to the high seas forecast issued by Meteo-France on the
website: https://wwmiws.wmo.int for more details.

East Atlantic Long-period N Swell: Large, long-period north swell
generated by a large fetch of gale to storm-force winds in the
northeast Atlantic will continue to propagate southward of 31N
through the weekend. Expect seas of 12-24 ft through Sat mainly N
of the Cape Verde Islands and east of 43W. Seas across these
northeastern waters will then gradually reduce in areal coverage
and subside below 12 ft near the Canary Islands on Mon. Please
refer to the latest High Seas Forecast issued by the National
Hurricane Center at website
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic through the coast of Guinea
near 10N14W, then curves southwestward to 04N17W. The ITCZ
continues from 04N17W to 00N30W to the coast of Brazil near
01S46W. Scattered moderate isolated strong convection is ongoing
from 03S to 05N west of 10W.

...GULF OF MEXICO...

A 1025 mb high pressure system near the mouth of the Mississippi
River dominates the Gulf of Mexico. The pressure gradient between
this ridge and lower pressures associated with a stationary front
east of the area results in fresh to strong NE winds across the
Florida Straits with rough seas, and moderate to fresh NE winds
and moderate seas elsewhere in the eastern Gulf, east of 90W.
Otherwise, moderate or weaker winds and slight to moderate seas
prevail elsewhere.

For the forecast, the pressure gradient between a ridge across
the Gulf region and a stationary front over the NW Caribbean Sea
will continue to support fresh to locally strong NE winds and
moderate to rough seas over the SE Gulf, including the Straits of
Florida, through Fri. A surface trough will come off the Yucatan
Peninsula every evening with moderate to fresh NE winds, which
will affect the eastern Bay of Campeche from Sat through Mon.
Elsewhere moderate or weaker winds, and slight to moderate seas
will prevail.

...CARIBBEAN SEA...

A stationary front extends from central Cuba to the Gulf on
Honduras. A surface trough is ahead of the front curving SE to NW
Colombia offshore waters. Low level convergence induced by both
the front and the pre-frontal trough continue to support scattered
showers across E Cuba and adjacent waters N of 17N. Moderate to
fresh northerly winds with seas to 7 ft are behind of the front
over the NW Caribbean. Over the eastern and central Caribbean,
moderate E to SE winds and moderate seas prevail.

For the forecast, fresh to locally strong N winds and rough seas
will continue to follow the stationary front through Fri night as
it transitions to a cold front today before dissipating offshore
Nicaragua late Fri. Afterward, moderate to fresh NE winds will
remain in the western Caribbean, including the lee side of Cuba
and the Windward Passage as high pressure develops across the
northern Bahamas in the wake of the front. As the ridge shifts
slightly eastward, fresh to strong winds will develop offshore
Colombia Sun through Mon night.

...ATLANTIC OCEAN...

Refer to the Special Features section for details on an east
Atlantic Gale Warning issued by Meteo-France, and associated large
northerly swells.

A stationary front extends from 31N69W to Andros Island to
central Cuba into the NW Caribbean. A pre-frontal trough is
analyzed from 30N66W to the southern Bahamas. Heavy showers and
isolated thunderstorms associated with both features cover the
offshore waters between 61W and 78W. Fresh to strong NE winds
and moderate to rough seas are noted behind of the front while
moderate to fresh SE winds are ahead of it along with moderate to
rough seas.

An extensive 1032 mb high pressure system centered near 38N44W
dominates the remainder SW N Atlantic and central subtropical
waters. Over the eastern subtropical waters, a cold front is
moving across the Canary Islands with a reinforcing front trailing
the leading front. The pressure gradient between the broad ridge
and the low pressure system associated with the front is
supporting fresh to near gale-force winds and very rough seas to
22 ft, N of 24N and east of 41W to the coast of Africa. Moderate
to fresh winds and rough seas under a relatively tight pressure
gradient are present between 60W and 41W, including the tropical waters.

For the forecast west of 55W, the front will remain nearly
stationary west of Bermuda to the central Bahamas today, then it
will transition to a cold front as a low pressure attached to the
front moves quickly NE of the forecast area through Sat night.
High pressure over the SE CONUS and over the north-central
Atlantic will continue to support fresh to strong winds and rough
seas on either side of the front and across the offshore forecast
waters N of 25N through the weekend. A new cold front is forecast
to enter the NE Florida offshore waters Mon night into Tue, which
will bring strong winds and rough seas to the area.

imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through 1020 UTC.

...SPECIAL FEATURES...

East Atlantic Gale Warning: Meteo-France has issued a gale
warning, in effect for the high seas zones of Irving, west of
Madeira, Meteor and Agadir, until 21/00 UTC at least, with severe
gusts. Please refer to the next Special Feature for details on
associated very large swells. Please refer to the high seas
forecast issued by Meteo-France on the website:
https://wwmiws.wmo.int for more details.

East Atlantic Long-period N Swell: Very large, long-period north
swell generated by a large fetch of gale to storm-force winds in
the northeast Atlantic will continue to propagate southward of 31N
through the weekend. Expect seas of 12-24 ft into Sat night,
mainly N of the Cape Verde Islands and east of 43W. Seas across
these northeastern waters will then gradually reduce in areal
coverage with the remaining very rough seas subsiding below 12 ft
near the Canary Islands Mon. Please refer to the latest High Seas
Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic through the coast of
Liberia near 06N11W, then curves southwestward to 04N14W. The
ITCZ extends from 04N14W to 01N30W to 01S47W. Scattered moderate
to isolated strong convection is observed from 06S to 05N and
west of 16W.

...GULF OF MEXICO...

Surface ridging anchored by a 1024 mb high near the mouth of the
Mississippi River extends basin-wide, maintaining fairly tranquil
weather conditions. The pressure gradient between this ridge and
a stationary front SE of the area is leading to fresh to locally
strong NE winds across the SE Gulf, along with moderate to rough
seas. Moderate or weaker winds and slight to moderate seas are elsewhere.

For the forecast, the pressure gradient between a ridge across
the Gulf region and a weakening stationary front over the western
Caribbean Sea will continue to support fresh to locally strong NE
winds and moderate to rough seas over the SE Gulf, including the
Straits of Florida, through today. Moderate to fresh NE winds are
expected nightly, through the forecast period, across the eastern
Bay of Campeche due to local effects associated with a thermal
trough. Elsewhere, moderate or weaker winds, and slight to
moderate seas will prevail through Tue night.

...CARIBBEAN SEA...

A weakening stationary front extends from eastern Cuba to the
offshore waters of northern Costa Rica. A few showers are noted
ahead of the front. Fresh to locally strong N winds prevail W of
the front, with seas to 7 ft. To the east of these features,
gentle to moderate E to SE winds, and slight to moderate seas prevail.

For the forecast, fresh to locally strong N winds and moderate to
rough seas will continue behind the front, which is forecast to
dissipate tonight over the SW Caribbean offshore waters.
Afterward, moderate to locally strong NE winds will remain in the
western Caribbean, including the lee side of Cuba and the Windward
Passage through Sun night as high pressure develops across the
northern Bahamas in the wake of the front. As the ridge shifts
slightly eastward, fresh to strong winds will also develop
offshore Colombia Sun evening and prevail through Tue night.

...ATLANTIC OCEAN...

Refer to the Special Features section for details on an east
Atlantic Gale Warning issued by Meteo-France and associated large
northerly swells across the far NE waters.

A stationary front extends from 31N66W to the central Bahamas and
eastern Cuba. A low pressure is now embedded within the front,
which is located near 27N70W. Scattered heavy showers are seen
mainly ahead of the frontal boundary to about 57W. High pressure
building behind the front is supporting fresh to strong northerly
winds and rough to very rough seas to the west of the front while
a broad surface ridge over the central Atlantic supports fresh to
strong southerlies ahead of the front and N of 25N. Rough seas to
10 ft are ahead of the front.

In the east Atlantic, a cold front is just E of the Canary
Islands, which extends to 21N23W to 23N38W. A reinforcing cold
front is approaching the Canary Islands. Strong to near gale
northerly winds and rough to very rough seas are north of 21N and
east of 42W, with hazardous marine conditions in association with
this front depicted further in the aforementioned Special Marine
section above. The rough seas in NE swell extend much farther S
and W, reaching to 15N and as far W as 55W.

For the forecast west of 55W, fresh to near gale force winds and
rough seas on either side of the front, and N of 25N, will
continue to affect the offshores from west to east through the Sun
night as the front transitions to a cold front today. Looking
ahead, a new cold front is forecast to enter the NE Florida
offshore waters Mon night into Tue, followed by fresh to strong NE
to E winds and rough seas. These marine conditions are forecast
to affect most of the waters N of 27N through the middle of the next week.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Mon Apr 13 2026

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 FEATURE...

Gale Warning E of 35W: Meteo-France has issued Gale Warnings for
the marine zones of Agadir through 14/12Z and Tarfaya through
14/00Z. The pressure gradient between a 1028 mb high pressure
located midway between the Azores and the Madeira Islands and
relatively lower pressures in NW Africa supports these gale force
winds (Force 8 on the Beaufort Wind Scale) with severe gusts.
Scatterometer data confirmed the presence of these winds. Very
rough seas, in long period NW swell, are also reaching this area.

Please refer to the Meteo-France High Seas Forecast product, listed
on the website at https://wwmiws.wmo.int for more information.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic through the coastal border
of Senegal and Guinea-Bissau near 12N16W, then continues SW to
near 06N20W. The ITCZ extends from 06N20W to NE Brazil near 03S44W.
Scattered moderate convection is noted S of 04N between 22W and 50W.

...GULF OF Mexico...

High pressure centered over the western Atlantic extends a ridge
across Florida into the Gulf region. Under the influence of this
system, fresh to strong NE to E winds and moderate to rough seas
are noted over the SE Gulf, including the Straits of Florida.
Similar wind speeds are observed W of the Yucatan peninsula
associated with a thermal trough. Moderate to locally fresh E to
SE winds and moderate seas are observed elsewhere, except in the
far NE Gulf where light to gentle winds and slight seas are
occurring. High clouds from the deep convection over eastern
Mexico are being carried across the northwestern Gulf by upper-level winds.

For the forecast, the ridge will maintain moderate to fresh E to
SE winds and mostly moderate seas through Fri. Expect stronger
winds to pulse across the SE part of the Gulf, including the
Florida Straits, through Tue, and off the Yucatan Peninsula each
night through Wed, driven by local effects associated with a
thermal trough.

...CARIBBEAN SEA...

A stationary front over the Atlantic that reaches Hispaniola and
a pre-frontal trough are helping to induce scattered to numerous
showers and thunderstorms over Hispaniola, the Mona Passage and
Puerto Rico. High pressure over the western Atlantic combined with
the Colombian low supports fresh to strong trades over the south-
central Caribbean, including the Gulf of Venezuela. Seas are 8 to
9 ft offshore Colombia. Fresh to strong winds and moderate seas
are also noted in the Windward Passage and in the lee of Cuba.
Moderate with locally fresh NE to E winds and 3 to 6 ft seas prevail
elsewhere in the Caribbean Sea.

For the forecast, high pressure over the western Atlantic combined
with the Colombian low will maintain fresh to strong trade winds
and rough seas over the south-central Caribbean and near the coast
of Colombia today, then mainly fresh winds are expected through
Wed night. Fresh to strong northeast winds and building seas will
prevail south of Cuba, in the Windward Passage, and south of
Hispaniola through the the middle of the week. Winds and seas will
diminish across the basin late in the week.

...ATLANTIC OCEAN...

Please read the Special Features section about Gale Warnings off Morocco.

Scattered to numerous showers and thunderstorms are active along
a stationary front that extends from 31N54W to Hispaniola. Fresh
to strong NE winds and seas of 8 to 10 ft are found near and
behind the aforementioned frontal boundary, with the exception of
moderate to locally fresh E winds and 6 to 7 ft seas off NE and
central Florida. High pressure follows the front and extends a
ridge across the western Atlantic and Florida into the Gulf of
Mexico. E of the front, high pressure of 1028 mb located midway
between the Azores and the Madeira Islands dominates the remainder
of the Atlantic forecast region. Fresh to strong N to NE winds
are noted per scatterometer data N of 10N and S of a line from
30N20W to 25N40W. Seas of 6 to 9 ft are within these winds.
Moderate to fresh winds and seas of 5 to 7 ft dominate the
remainder of the tropical Atlantic. Elsewhere, moderate or weaker
winds and moderate seas prevail.

For the forecast west of 55W, the above mentioned front will dissipate
late today but a frontal trough will persist reaching Puerto Rico
by this evening. Then, the frontal trough will move westward through
Wed while weakening. Fresh to strong NE winds and rough seas will
persist west of the front/trough mainly south of 27N through midweek,
then diminishing through Fri.
