    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Mon Jan 26 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 1000 UTC.

    ...SPECIAL FEATURES...

    Gulf of Mexico Gale Warning: A strong cold front continues to
    move E-SE across the Gulf this morning, and extends from the
    Florida Big Bend southwestward to 20N94W then southward and
    inland across Mexico E of Coatzacoalcos. Strong to near gale-
    force N winds and rough to very rough seas are found behind the
    front. Recent satellite scatterometer data indicated that
    northerly gales were occurring offshore Tampico, and are expected
    to begin across the waters near Veracruz by sunrise. These gale
    conditions are forecast to continue offshore Tampico through this
    morning and offshore Veracruz through late Mon night. The cold
    front will sweep across the rest of the basin tonight through Mon
    evening. Seas are expected to quickly build across the Gulf region
    through Mon reaching 16 or 17 ft across SW portions. Marine
    conditions will improve from NW to SE Tue through Wed as the
    front moves southeastward into the NW Caribbean and high pressure
    settles across the northern Gulf. Mariners are advised to keep up
    with the latest forecasts.

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

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough reaches the Atlantic through the coast of
    Guinea near 10N14W and continues southwestward to 03.5N19W. The
    ITCZ extends from 03.5N19W to 04N43W and to 00.5N50W. Scattered
    moderate isolated strong convection is observed south of 08N
    between 13W and 52W.

    GULF OF MEXICO...

    Please read the Special Features section for details on the Gale
    Warning in effect for the western and SW Gulf.

    A cold front extends from the Florida Big Bend southwestward to
    20N94W then southward and inland across Mexico E of Coatzacoalcos.
    Modified arctic air is spilling across the entire basin behind the
    front to produce a blanket of cold air stratus behind the front.
    Area radars show fine lines of moderate showers along and ahead of
    the front across the eastern Gulf and into Florida, with a few
    isolated strong showers. Gulf buoys show seas have reached 10 ft
    across NW and SW central portions, outside of the strongest winds.
    Winds offshore of Tampico are likely 12-13 ft already. Ahead of
    the front, moderate to locally fresh S to SW winds and moderate
    seas to 6 ft prevail.

    For the forecast, the cold front will sweep across the rest of
    the basin through Mon evening with very rough seas expected to
    quickly build across the basin today and tonight. Marine
    conditions will improve from NW to SE Tue through Wed as the front
    moves southeastward into the NW Caribbean and high pressure
    settles across the northern Gulf. The high will shift southeastward
    Thu as low pressure develops in the far western Gulf along the
    next cold frontal boundary. This front is expected to reach from
    the Florida Panhandle to Veracruz by Fri evening.

    CARIBBEAN SEA...

    Generally stable conditions prevail across the Caribbean waters.
    Satellite imagery shows scattered shallow light showers extending
    across the basin from south of Jamaica east and southeastward to
    the Lesser Antilles. A broad high pressure ridge north of the
    area supports fresh to strong easterly winds and rough seas to
    near 8 ft off northern Colombia. Moderate to fresh easterly
    breezes and moderate seas are prevalent in the north- central and
    eastern Caribbean and Gulf of Honduras. Elsewhere, moderate or
    lighter winds and slight to moderate seas are evident.

    For the forecast, high pressure NE of Bermuda will slide SE and
    weaken through Tue and maintain a ridge N of the Caribbean basin,
    supporting mostly fresh trades over the eastern and central
    Caribbean as well as the Tropical N Atlantic waters, while fresh
    winds offshore of Colombia pulse to strong at night. Large E swell
    over the Tropical N Atlantic will slowly subside into early next
    week, with seas lingering near 8 ft through early Wed. A cold
    front will enter the NW Caribbean late today and begin to stall
    from eastern Cuba to NE Honduras by late Tue into Wed. Strong
    northerly winds will follow the front before briefly diminishing
    to mostly fresh on Wed, and increasing to fresh to strong Wed
    night and Thu as stronger high pressure builds southward across
    the N Gulf of Mexico.

    ATLANTIC OCEAN...

    A 1027 mb high is centered NE of Bermuda near 35N54W and extends a
    broad ridge southwestward across the NW Bahamas, south Florida
    and through the Straits of Florida. A 1011 mb low center of
    located over central Georgia, with a strong cold front then
    trailing southwestward across the Gulf of Mexico. A tight
    pressure gradient between the ridge and the low center supports
    fresh to strong southerly winds and rough seas to 8 ft north of
    28N and west of 75W. Farther east, a cold front enters the
    tropical Atlantic near 31N39W and continues southwestward to
    28N50W and then as a stationary front to 31N63W. Moderate to
    locally fresh E winds and rough seas 8 to 12 ft in N swell are
    found north of the boundary. The remainder of the basin is under
    the influence of a broad subtropical ridge that sustains moderate
    to fresh easterly winds and moderate to rough seas 7 to 10 ft
    south of 25N and between the Bahamas and Africa. Elsewhere,
    moderate or weaker winds and moderate to locally rough seas
    prevail. A band of multilayer clouds associated with very strong
    winds aloft persist across the tropical Atlantic, extending from
    NE South America all the way to W Africa.

    For the forecast west of 55W, fresh to strong SW winds over the
    NW forecast waters will continue through mid morning in advance of
    a strong cold front that is expected to move offshore northeast
    Florida this morning, accompanied by scattered showers and
    thunderstorms. The front will reach from near 31N73W to the NW
    Bahamas and S Florida Mon evening, from near 31N57W to the Turks
    and Caicos Islands and eastern Cuba Tue evening, then begin to
    become stationary and weaken as it reaches from near 28N55W to the
    SE Bahamas and to eastern Cuba Wed evening. Fresh to strong NW to
    N winds and rough seas are expected W of the front this afternoon
    through Tue afternoon. The frontal boundary will begin to
    dissipate on Thu as another cold front moves out across the
    western forecast waters, reaching from near 29N55W to the central
    Bahamas Fri morning, before stalling N of 24N Fri night.

    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Tue Jan 27 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 1000 UTC.

    ...SPECIAL FEATURES...

    Gulf of Mexico Gale Warning: A strong cold front has moved
    southeast of the basin and into the NW Caribbean overnight, and
    extends from the NW Bahamas southwestward across central Cuba and
    into south central Belize. 1039 mb high pressure across SW
    Louisiana and SE Texas extends a ridge south and southeastward
    behind the front, forcing strong northerly winds across the
    entire basin, except across NW portions, where moderate N to NE
    winds prevail. NW gales near Veracruz has diminished slightly
    overnight, to around 35 kt, where seas are 16-18 ft, as confirmed
    by overnight satellite altimeter data. Very rough seas of 12 ft
    and higher prevail elsewhere S of 20N across most of the Bay of
    Campeche, and near the NE coast of the Yucatan Peninsula and
    through the Yucatan Channel. Gales off of Veracruz are expected
    to diminish to 25-30 kt by sunrise. Marine conditions will improve
    from NW to SE across the basin today through Wed as the front
    moves farther southeastward into the NW Caribbean and high
    pressure settles across the northern Gulf.

    Atlantic Gale Warning: A strong W Atlantic cold front extends
    through 31N69W southwestward across the NW Bahamas and through
    central Cuba. Behind the front, strong high pressure across the NW
    Gulf of Mexico extends east and southeastward behind the front,
    and is forcing strong NW to N winds and rough seas across the
    Atlantic waters. Northerly gales have been occurring overnight near
    and offshore NE Florida to the Cape Canaveral area over and east
    of the Gulfstream, and are expected to diminish below gale-force
    by sunrise. Seas in this area area are 10-13 ft in N swell moving
    against the Gulfstream current. The front will move from near
    31N56W to the SE Bahamas and eastern Cuba this evening, then
    become stationary and weaken as it reaches from near 29N55W to the
    SE Bahamas and east Cuba Wed evening. As this occurs, winds will
    gradually diminish from NW to SE today and tonight. Moderate to
    large NW swell generated behind the front will gradually move SE
    of this area tonight through Wed.

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

    Significant rainfall event: A cold front is entering the NW
    Caribbean and forecast to stall from eastern Cuba to NE Honduras
    by late today into Wed. As the front becomes nearly stationary
    over the NW Caribbean, the northerly winds behind it will
    transport abundant tropical moisture into the Gulf of Honduras and
    northern Honduras, where the onshore flow will favor the
    development of showers and thunderstorms. Deep tropical moisture
    will remain in place across southern Mexico and northern Central
    America supporting more shower and thunderstorm activity with
    rainfall amounts of 2 to 4 inches, and localized amounts of 4 to
    6 inches due to orographic effects. The heaviest rainfall is
    expected in southern Mexico late tonight into Tue, and in northern
    Guatemala and Belize Tue into early Wed, and well as in northern Honduras.

    Please follow your local weather office for more details.

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough reaches the Atlantic through the coast of
    Guinea near 10N14W and continues southwestward to 03N22W. The
    ITCZ extends from 03N22W to 00N34W and to the coast of Brazil near
    03S40W. Scattered moderate isolated strong convection is observed
    south of 06N and between 08W and 51W.

    GULF OF MEXICO...

    Please read the Special Features section for details on the Gale
    Warning in effect for the SW Gulf.

    A strong cold front extends has moved southeast of the basin and
    into the NW Caribbean overnight, and extends from the NW Bahamas
    southwestward across central Cuba and into south central Belize.
    1039 mb high pressure across SW Louisiana and SE Texas extends a
    ridge south and southeastward behind the front, forcing strong
    northerly winds across the entire basin, except across NW
    portions, where moderate N to NE winds prevail. Seas of 8 ft and
    greater are generally S of a line from Cedar Key, Florida to
    28N88W to near Tampico, Mexico. Recent buoy observations show seas
    of 10-12 offshore of the Tampa bay area. Peak seas across
    the basin of 15-18 ft are over the SW Gulf across and downwind of
    gales off of Veracruz.

    For the forecast, marine conditions will improve from NW to SE
    today through Wed as the front moves farther southeastward into
    the NW Caribbean and high pressure settles across the northern
    Gulf. The high will shift southeastward on Thu as low pressure
    develops in the north- central Gulf along the next cold front.
    This front is expected to reach from the Florida Panhandle to
    Veracruz by Fri evening and move SE of the basin Sat. Another
    round of strong northerly winds will follow this front, with gale-
    force winds near Veracruz likely to begin Sat morning.

    CARIBBEAN SEA...

    A cold front has moved into the NW Caribbean overnight, extending
    from central Cuba to south central Belize. A few clusters of
    moderate showers are along the front. Strong northerly winds to 30
    kt and rough seas are noted behind the front, as depicted by
    overnight satellite scatterometer data. Seas of 10-12 ft are
    currently across the Yucatan Channel. Meanwhile, the remainder of
    the basin is under the influence of a broad subtropical ridge
    over the central Atlantic. Fresh to strong easterly winds and
    rough seas to 9 ft are found off Colombia. Moderate to fresh
    easterly winds and moderate seas are noted in the north- central
    and eastern Caribbean. Elsewhere, light to gentle winds and slight
    seas prevail.

    For the forecast, high pressure over the central Atlantic will
    slide E-SE and weaken through Tue night and maintain a ridge N of
    the Caribbean basin. This pattern will support fresh trades over
    the eastern and central Caribbean as well as the Tropical N
    Atlantic waters through early Wed, while fresh winds offshore of
    Colombia pulse to strong at night through Thu. Large E swell over
    the Tropical N Atlantic will slowly subside through Wed afternoon.
    The cold front over the NW basin will move SE today and begin to
    stall and weaken from eastern Cuba to NE Honduras this evening
    through Wed. Strong northerly winds will follow the front before
    briefly diminishing to mostly fresh Wed morning, then increase to
    fresh to strong Wed afternoon through Thu as stronger high
    pressure builds southward across the N Gulf of Mexico. Mainly
    moderate N winds and seas will prevail over the NW Caribbean Thu
    night through Fri night. Looking ahead, a new strong cold front
    will move into the NW basin Sat.

    ATLANTIC OCEAN...

    Please read the Special Features section about the Gale Warning
    off NE Florida.

    A strong cold front extends from 31N69W across the NW Bahamas and
    into central Cuba. Scattered showers are noted along this
    boundary. Fresh to near gale-force N winds and rough seas prevail
    behind this boundary. Fresh to strong SW winds and rough seas are
    found ahead of the front to 60W and north of 28N. The rest of the
    tropical Atlantic is dominated by a broad subtropical ridge that
    extends from 1025 mb high pressure near 30N40W to the central
    Bahamas. Moderate to fresh easterly trade winds and moderate to
    rough seas in a mix of E and N swell are found south of 25N and
    east of 65W to 30W. A cold front is found SE of the central
    Atlantic high, from 31N20W to 28N35W, with moderate to fresh winds
    on both sides of the front.

    In the far NE Atlantic, a strong low pressure off Ireland is
    producing fresh to strong W winds and rough seas to the area north
    of the Canary Islands and east of 25W. Northerly swell associated
    with this feature is progressing southward, producing seas of
    8-16 ft north of 25N and east of 55W. Elsewhere, moderate or
    weaker winds and moderate seas prevail.

    For the forecast west of 55W, the cold front will reach from near
    31N56W to the SE Bahamas and eastern Cuba this evening, then
    become stationary and weaken as it reaches from near 29N55W to the
    SE Bahamas and east Cuba Wed evening. The frontal boundary will
    meander across this area through Thu, when new high pressure
    across the Gulf of Mexico will build eastward into the W Atlantic
    and freshen winds behind the lingering front through Thu evening.
    Looking ahead, another strong cold front will enter the western
    waters on Sat. Associated low pressure is forecast to deepen
    rapidly across the NW Atlantic Sat through Sun.

    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Thu Jan 29 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 1000 UTC.

    ...SPECIAL FEATURES...

    Significant rainfall event: A weakening stationary front extends
    from E Cuba to the SE coastal waters of Nicaragua. This boundary,
    along with low level onshore flow, will allow for deep moisture
    to prevail in the area. Heavy rainfall is expected through Thu,
    with 2 to 4 inches of rainfall possible primarily over northern
    Honduras, eastern Guatemala, and coastal Belize, and isolated 4+
    inches possible along the windward slopes and near the north coast
    of Honduras where the onshore flow persists. Marine interests in
    the Gulf of Honduras should also be aware as scattered showers and
    isolated thunderstorms will prevail in the area through today.
    Please follow your local weather office for more details.

    Gulf of Mexico Gale Warning: Another cold front is expected to
    move off the Texas coast late tonight. Fresh to strong NW to N
    winds and building seas will follow the front as it reaches from
    Panama City, Florida to just N of Veracruz, Mexico by Fri evening.
    An associated complex area of low pressure will rapidly deepen
    Fri through Sat as it moves from the SE U.S. into the western
    Atlantic. This will reinforce the front as it moves southeast of
    the Gulf basin on Sat, and usher in another blast of arctic air
    across the Gulf. This will support winds to gale-force near
    Veracruz early Sat morning through midday Sat, and across the
    eastern Gulf Sat through Sat evening. Very large seas are expected
    to build behind this front Fri night through Sun, reaching 15 to
    18 ft across eastern portions of the basin and into the western
    Florida coastal waters.

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough enters the Atlantic through the coast of
    Guinea near 11N14.5W and continues southwestward to 04.5N19W. The
    ITCZ extends from 04.5N19W to the coast of Brazil near 01S47W.
    Scattered moderate convection is noted from 01.5S to 05N between
    19W and 50W. Scattered moderate to strong convection is noted from
    01.5S to 03N E of 14W.

    GULF OF MEXICO...

    See the Special Features section above for information on a Gale
    Warning for the SW Gulf, expected to begin in 48 hours.

    1028 mb high pressure has drifted southeastward into the NW Gulf
    tonight, centered offshore the Louisiana coast near 29N92.5W. A
    surface trough in the central Gulf to near the Yucatan coast, and
    a coastal trough in the SW Gulf support some cloudiness in the
    basin, although any shower activity associated with this
    convection is very light. The pressure gradient between the high,
    the central Gulf trough, and a lingering front in the NW Caribbean
    is producing mostly fresh N winds across the SE Gulf and into the
    NW Caribbean this morning, where seas are 4 to 7 ft, highest in
    the Yucatan Channel. Moderate NE winds prevail across the Bay of
    Campeche to the west of the coastal trough, with seas of 4 to 5
    ft. Elsewhere, moderate or lighter winds and slight to moderate seas prevail.

    For the forecast, the fresh N winds across the SE Gulf will
    gradually diminish through morning, as the front in the NW
    Caribbean drifts southward. High pressure over the southern
    Plains will shift east today ahead of a low pressure area moving
    into the lower Mississippi Valley, with a trailing cold front
    moving off the Texas coast late tonight. Fresh to strong NW to N
    winds and building seas will follow the front as it reaches from
    Panama City, Florida to just N of Veracruz, Mexico by Fri evening.
    The low will rapidly deepen Fri through Sat as it moves into the
    western Atlantic. This will reinforce the front as it moves
    southeast of basin Sat, and usher in another blast of arctic air
    across the Gulf. This will support winds to gale-force near
    Veracruz early Sat morning, and across the eastern Gulf Sat
    through Sat evening, with rough to very rough seas across the
    basin. Looking ahead, winds and seas will diminish from west to
    east across the Gulf Sun through Mon as high pressure shifts SE
    into the northern Gulf following the front.

    CARIBBEAN SEA...

    Refer to the section above for details on the significant rainfall
    even expected over the Honduras/Nicaragua area through Thu.

    A lingering front remains nearly stationary from the east coast of Cuba
    to the SE coastal waters of Nicaragua, where it has been drifting
    southward overnight. Stratocumulus clouds and light showers cover
    much of the NW Caribbean behind the front. The tight pressure
    gradient between this front and the ridge over the southern
    United States and Gulf of Mexico supports fresh to strong
    northerly winds and moderate to rough seas behind the boundary.
    Seas remain 7 to 10 ft across much of this area. In the south-
    central Caribbean, recent satellite scatterometer data captured
    fresh to strong NE winds S of 13.5N to the coast of Colombia.
    Seas in these waters are 6-8 ft. Elsewhere, moderate or weaker
    winds and slight to moderate seas are prevalent.

    For the forecast, the aforementioned front has begun to drift
    southward across the western Caribbean, as high pressure across
    the NW Gulf of Mexico is starting to shift eastward. Fresh to
    strong N winds will prevail across NW portions behind the front
    through this evening, and force it slowly southward, reaching E
    Cuba to near the Nicaragua-Costa Rica border, where it will stall
    and begin to weaken this evening through Fri. An unusually strong
    cold front will move into the NW basin Sat morning and move
    southeastward, merging with the old lingering front from E Cuba to
    western Panama Sat evening, from eastern Hispaniola to the NW
    coast of Colombia Sun evening, then begin to stall from eastern
    Puerto Rico to NW Colombia Mon evening. Strong to near gale-force
    N winds are expected behind this front, generating very rough seas.

    ATLANTIC OCEAN...

    An Atlantic front is stationary from 31N48W to 1014 mb low
    pressure near 25N67W to the east coast of Cuba. Scattered light to
    moderate showers are evident along the front and E through NE of
    the low. Moderate to fresh northerly winds and seas of 5-8 ft are
    occurring behind the boundary and south of 27N, except seas of 9
    to 10 ft within 120 nm N of the front due to fresh winds. Moderate
    to fresh SW winds and seas of 8-14 ft in NW swell are found north
    of 27N and east of the front to 35W. North of the stalled front,
    a reinforcing front is moving southeast of Bermuda, with fresh to
    locally strong westerly winds and moderate to rough seas to 9 ft
    in W-NW swell occurring north of 30N and west of 65W.

    The remainder of the tropical Atlantic is dominated by a 1025 mb
    high pressure near 27N27W that extends west-southwestward to
    Hispaniola. Moderate to fresh easterly winds and moderate to
    locally very rough seas in mixed N and E swell are found south of
    24N and east of 60W. The strongest winds and highest seas are
    found in the eastern Atlantic. Large northerly swell spreads
    across the eastern Atlantic due to a strong low pressure well
    north of the area. Rough to very rough seas of 12 to 15 ft are
    found north of 24N and east of 40W. Elsewhere, moderate or weaker
    winds and moderate seas prevail.

    For the forecast west of 55W, the aforementioned front will
    meander across this area through tonight. High pressure across
    the Gulf of Mexico will build eastward into the W Atlantic and
    freshen winds behind the lingering front today and tonight, and
    nudge the front southward to near the Atlantic approach to the
    Windward Passage. An unusually strong cold front will enter the
    western Atlantic waters Sat morning. Associated complex low
    pressure is forecast to deepen rapidly across the NW Atlantic Sat
    through Sun, inducing a very large area of westerly gale-force
    winds covering the local waters N of 23.5N, and the central
    Bahamas, Sat through Sun evening, before lifting N of the area Sun
    night. The front is expected to reach from 31N73W to eastern Cuba
    Sat evening, from 31N60W to eastern Hispaniola Sun evening, then
    begin to weaken and stall from 27N55W to eastern Puerto Rico Mon evening.
