    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Sat Jan 10 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 0800 UTC.

    ...SPECIAL FEATURES...

    Caribbean Sea Gale Warning: Strong to near gale force NE to E
    winds will pulse offshore of NW Colombia through Sun night due to
    the gradient between building high pressure N of the region and
    low pressure over northern Colombia, except minimal gale force
    until around sunrise this morning. Seas to 12 ft will occur
    within these winds. After Sun night, fresh to locally strong
    winds will prevail there.

    Gulf of Mexico Gale Warning: A strong cold front will move off
    the coast of Texas this morning. Strong to near-gale force N
    winds following the front will rapidly reach gale force near
    Tampico late this morning and afternoon, and in Veracruz adjacent
    waters this evening through Mon. Winds may peak around 45 kt near
    Veracruz. Seas will quickly build and likely peak at around 21 ft
    offshore of Veracruz Sun and Sun night. The front will weaken and
    stall from near western Cuba to the Yucatan Channel to the
    eastern Bay of Campeche by Mon evening. Conditions in the SW Gulf
    will gradually improve Mon night into Tue.

    Please read 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 and then continues to 06N18W. The ITCZ extends from
    06N18W to 04N35W and to 01N50W near the coast of Brazil. Widely
    scattered moderate convection is observed mainly south of 08N.

    ...GULF OF Mexico...

    A Gale Warning is in effect for the W-central Gulf and western
    Bay of Campeche area. Please read the Special Features section
    above for details.

    A subtropical ridge over the western Atlantic extends southwestward
    to the Gulf of Mexico. The pressure gradient between this ridge
    and lower pressures associated with a cold front over the southern
    United States result in moderate to fresh SE-S winds over much of
    the basin, especially east of 96W. Seas in these waters are 3-6
    ft. Elsewhere, light to gentle winds and slight to moderate seas
    prevail. Areas of dense fog are present within 20 nm of shore of
    SE Louisiana to nearshore of the western Florida Panhandle.

    For the forecast, moderate to fresh SE winds will diminish this
    morning as a cold front near the Texas coast enters the basin.
    Strong to near- gale force N winds following the front will
    rapidly reach gale force near Tampico late this morning and
    afternoon, and in Veracruz adjacent waters this evening through
    Mon. Winds may peak around 45 kt near Veracruz. Seas will quickly
    build and likely peak at around 21 ft offshore of Veracruz Sun and
    Sun night. The front will weaken and stall from near western Cuba
    to the Yucatan Channel to the eastern Bay of Campeche by Mon
    evening. Conditions in the SW Gulf will gradually improve Mon
    night into Tue. Moderate or lighter winds and slight to moderate
    seas will prevail across the basin through early Wed. The next
    cold front could impact the basin with increasing winds and
    building seas by Wed night.

    ...CARIBBEAN SEA...

    A Gale Warning is in effect the waters off NW Colombia. Please
    read the Special Features section above for details.

    The tight pressure gradient between the subtropical ridge over
    the western Atlantic and lower pressures in NW South America
    results in strong to near gale-force NE winds in the south-central
    Caribbean. This was confirmed by earlier scatterometer satellite
    passes. Seas in these waters are 8-12 ft. Elsewhere, moderate to
    fresh easterly winds and moderate seas prevail, except locally
    fresh to strong in the Lee of Cuba, across and through the
    approach to the Windward Passage, and offshore southern Haiti. No
    significant convection is noted across the Caribbean basin.

    For the forecast, strong to near gale force NE to E winds will
    pulse offshore of NW Colombia through Sun night due to the
    gradient between building high pressure N of the region and low
    pressure over northern Colombia, except minimal gale force until
    around sunrise today. Seas to 12 ft will occur within these winds.
    After Sun night, fresh to locally strong winds will prevail
    there. Moderate to fresh NE to E winds are forecast elsewhere in
    the central and SW Caribbean, including the Windward Passage and
    Hispaniola adjacent waters. Locally strong winds will be likely
    pulsing at night over the Windward Passage and S of Hispaniola
    through Sat night, with similar winds pulsing in the lee of Cuba
    early today and Sat night. Elsewhere, moderate or weaker winds
    will prevail, except for moderate to fresh winds near the Gulf of
    Honduras this morning. A decaying cold front may move into or near
    the far NW Caribbean early next week where it will stall and wash out.

    ...ATLANTIC OCEAN...

    A broad 1028 mb high pressure system centered northwest of Bermuda
    near 34N66W dominates much of the SW North Atlantic, west of 55W.
    A cold front extends from near 31N49W to 26N60W, where it becomes
    a frontal trough to 25N65W to 28N74W. Moderate to fresh NE-E
    winds and moderate seas are found west of a line from 31N50W to
    Puerto Rico. Meanwhile, the central and eastern tropical Atlantic
    waters are dominates by a 1032 mb high pressure system located
    northwest of Madeira. A tight pressure gradient forces fresh to
    strong easterly winds and moderate to rough seas across much of
    the waters east of 44W. Elsewhere, moderate or weaker winds and
    moderate seas are prevalent.

    For the forecast west of 55W, high pressure building and sliding
    eastward in the wake of a cold front that extends from 27N55W to
    26N59W continuing as a frontal trough to 25N65W and 28N74W will
    support moderate to fresh NE winds across the waters E of the
    Bahamas, the Great Bahama Bank, and the approaches to the Windward
    Passage through Sun, with locally strong winds near the Windward
    Passage as the front washes out. A new cold front will emerge off
    the NE Florida coast Sun. Fresh to strong NW winds and rough seas
    will follow this front, which is forecast to reach from Bermuda to
    the northern Bahamas by Mon morning. Thereafter, the front will
    become stationary as it dissipates Mon night into Tue. The next
    cold front may enter the NW waters by Wed night.

    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Sun Jan 11 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 0800 UTC.

    ...SPECIAL FEATURES...

    Gulf of Mexico Gale Warning: A strong cold front extends from
    the Florida Panhandle to the central Bay of Campeche. Gale force N
    winds have diminished slightly near Tampico, Mexico while they
    continue S of 22N offshore Veracruz with an earlier ASCAT
    scatterometer pass showing winds around 45 kt and they could be
    slightly higher. Gale conditions are expected in Veracruz
    adjacent waters through Mon. Winds may continue to peak around 45
    kt near Veracruz early today. Seas will continue to build and
    likely peak at around 21 ft offshore of Veracruz today and tonight.
    The front will weaken and stall from near western Cuba to the
    Yucatan Channel to the eastern Bay of Campeche by Mon evening.
    Conditions in the SW Gulf will gradually improve Mon night into
    Tue. Please read 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 Sierra Leone near
    08N13W, then runs southwestward to 05N18W. The ITCZ continues
    from 05N18W to the coast of Brazil at 00.5N50W. Scattered
    moderate convection is noted from 03N to 10N between 22W and 52.5W.

    ...GULF OF MEXICO...

    A Gale Warning is in effect for the W-central Gulf and western
    Bay of Campeche. Please read the Special Features section above for details.

    As previously mentioned, a strong cold front extends from the
    Florida Panhandle to the central Bay of Campeche. Strong to near
    gale force northerly winds are behind the front with gale force
    winds S of 22N, along with rough to very rough seas. A narrow
    band of showers and thunderstorms is along the front, primarily S
    of 25N. Scattered showers and thunderstorms are also seen on
    conventional infrared satellite imagery in the eastern Bay of
    Campeche with a surface trough analyzed along the W coast of the
    Yucatan Peninsula. The remainder of the area is under the
    influence of a surface ridge, that extends from near Bermuda,
    across Florida into the Gulf region. Gentle to moderate SE to S
    winds and moderate seas are ahead of the front, with the exception
    of slight seas within 120 nm of the Florida Peninsula.

    For the forecast, as the front continues to move through the
    basin winds will peak around 45 kt near into today. Seas will
    continue to build and likely peak at around 21 ft offshore of
    Veracruz today and tonight. The front will weaken and stall from
    near western Cuba to the Yucatan Channel to the eastern Bay of
    Campeche by Mon evening. Conditions in the SW Gulf will gradually
    improve Mon night into Tue. Moderate or lighter winds and slight
    to moderate seas will prevail across the basin through early Wed.
    The next cold front could impact the basin with increasing winds
    and building seas by Wed night, with that front rapidly shifting
    SE of the basin Thu.

    ...CARIBBEAN SEA...

    The tight pressure gradient between the subtropical ridge over
    the western Atlantic and lower pressures in NW South America
    results in strong to near gale-force NE winds in the south-central
    Caribbean. Seas in these waters are in the rough range.
    Elsewhere, moderate to fresh easterly winds and moderate seas
    prevail. Patches of low level moisture, embedded in the trade
    wind flow, are moving across the basin producing isolated to
    scattered passing showers.

    For the forecast, strong to near gale force NE to E winds will
    pulse offshore of NW Colombia through tonight due to the pressure
    gradient between building high pressure N of the region and low
    pressure over northern Colombia, resulting in rough seas. After
    tonight, fresh to locally strong winds will prevail there. Pulsing
    moderate to fresh NE to E winds are forecast elsewhere in the
    central and SW Caribbean, including the Windward Passage and
    Hispaniola adjacent waters through at least the early part of the
    week. Elsewhere, moderate or weaker winds will prevail. A decaying
    cold front may move into or near the far NW Caribbean early this
    week where it will stall and wash out. Another front may move into
    the NW basin Thu.

    ...ATLANTIC OCEAN...

    A broad 1027 mb high pressure system centered NE of Bermuda near
    32.5N52.5W extends a ridge across the western Atlantic, Florida
    and the Bahamas. A surface trough is analyzed from 31N37W to
    24N49W, with an inverted trough analyzed near 55W from 20N to 29N.
    Moderate to fresh NE to E winds and moderate seas prevail across
    most of the waters N of 20N and W of 50W except weaker right under
    the ridge axis. An area of showers and thunderstorms is on the E
    side of the inverted trough. This convective activity covers
    roughly the waters from 20N to 28N between 50W and 57W. Farther
    E, high pressure of 1028 mb located near the Madeira Islands
    dominates the remainder of the Atlantic forecast region. The
    pressure gradient between the high pressure and lower pressures in
    the vicinity of the Monsoon trough/ITCZ is generating a large
    area of fresh to strong NE to E winds from 07N to 25N E of 35W to
    the coast of W Africa, along with rough seas. Moderate to fresh
    trade winds and moderate seas are noted over the remainder of the
    tropical Atlantic. Elsewhere, moderate or weaker winds and
    moderate seas are prevalent.

    For the forecast west of 55W, a cold front will emerge off the NE
    Florida coast later today. Fresh to strong NW winds and rough
    seas will follow this front, which is forecast to reach from
    Bermuda to the northern Bahamas by Mon morning. Thereafter, the
    front will become stationary as it dissipates Mon night into Tue.
    The next cold front may enter the NW waters by Wed night, reaching
    from near Bermuda to the SE Bahamas late Thu night, with
    associated gale winds possible N of 29N Thu night.

    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 0800 UTC.

    ...SPECIAL FEATURES...

    Gulf of Mexico Gale Warning: A cold front is moving across the
    Gulf from near S Florida to N of the Yucatan Channel to the
    central Bay of Campeche where it is stalling. Gale force NW to N
    winds to 40 kt with seas to 18 ft are occurring over the SW Gulf
    in the wake of the front. Strong northerly winds and moderate to
    rough seas follow the front elsewhere. The front will weaken and
    stall from western Cuba to the northern Yucatan peninsula to the
    eastern Bay of Campeche by Tue morning. Conditions in the SW Gulf
    will gradually improve tonight into Tue. Please read 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 exits the coast of Guinea near 10.5N14W and
    continues to 04N20W. The ITCZ extends from 04N20W to the coast of
    northern Brazil near 02N50W. Scattered moderate convection is
    from 01N to 09N between 22W and 45W.

    ...GULF OF MEXICO...

    Please see the Special Features section for information on a Gale Warning.

    A cold front is moving across the Gulf from near S Florida to N
    of the Yucatan Channel to the central Bay of Campeche where it is
    stalling. Gale force NW to N winds to 40 kt with seas to 18 ft are
    occurring over the SW Gulf in the wake of the front. Strong
    northerly winds and moderate to rough seas follow the front
    elsewhere. Moderate to fresh NE winds and slight to moderate seas
    are analyzed ahead of the front in the far SE Gulf and the
    Straits of Florida.

    For the forecast, the front will weaken and stall from western
    Cuba to the northern Yucatan peninsula to the eastern Bay of
    Campeche by Tue morning. Conditions in the SW Gulf will gradually
    improve tonight into Tue. Moderate or lighter winds and slight to
    moderate seas will prevail across the basin through early Wed. The
    next cold front could impact the basin with increasing winds and
    building seas by Wed night, with that front rapidly shifting SE of
    the basin Thu. Conditions should improve by the end of the week.

    ...CARIBBEAN SEA...

    A strong and broad ridge north of the Caribbean continues to
    support strong to near gale-force NE-E winds and rough seas in the south-central Caribbean. Elsewhere, moderate to fresh NE-E
    breezes and moderate seas prevail. No significant convection is
    noted in the Caribbean.

    For the forecast, strong to near gale force NE to E winds will
    pulse offshore of NW Colombia through much of the week due to the
    pressure gradient between high pressure NE of the region and low
    pressure over northern Colombia, resulting in rough seas. Pulsing
    moderate to fresh NE to E winds are forecast south of Hispaniola,
    in the Windward passage, and in the lee of Cuba through the early
    part of the week. Elsewhere, moderate or weaker winds will
    prevail. A weakening stationary front is forecast to extend across
    western Cuba and the northern Yucatan peninsula by Tue morning
    while gradually dissipating. Another cold front may move into the
    NW part of the basin Thu.

    ...ATLANTIC OCEAN...

    A strong cold front extends from just W of Bermuda to the
    northern Bahamas and S Florida with fresh to strong winds and
    rough to very rough seas building behind it. The remainder of the
    SW North Atlantic, west of 55W, is under a weak pressure gradient
    that supports moderate or weaker winds and moderate seas.

    A surface trough is analyzed at 64W and north of 20N. The
    interaction of this feature and divergence aloft sustains
    scattered showers east of the boundary. The remainder of the
    tropical Atlantic is under the influence of a broad subtropical
    ridge over the far NE Atlantic. Moderate to locally fresh easterly
    winds and seas of 4-8 ft are noted between 42W and 55W. Moderate
    to fresh easterly breezes and seas of 5-9 ft are found south of
    25N and east of 40W. Elsewhere, moderate or weaker winds and
    moderate seas prevail.

    For the forecast west of 55W, the front will become stationary as
    it dissipates on Tue. Then, high pressure will follow the front.
    Looking ahead, the next cold front may enter the NW waters by Wed
    night, reaching from near Bermuda to the SE Bahamas late Thu
    night. At that time, gale conditions are possible in the wake of
    the front near 31N with building seas across the waters.

    imagery, weather observations, radar and meteorological analysis.

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

    ...SPECIAL FEATURES...

    Atlantic Gale Warning: A cold front will enter the NW waters later
    this morning, reaching from near Bermuda to the SE Bahamas Fri
    morning, and extending from 31N59W to 25N70W Sat morning where it
    will stall and weaken. Widespread fresh to strong winds and rough
    seas will accompany the front through Fri. Winds are forecast to
    reach gale force ahead and behind the front N of 29N by this
    evening. A reinforcing front may impact the basin late in the
    upcoming weekend, bringing strong to near gale force winds and rough seas.

    Gulf of Mexico Gale Warning: A cold front extends from the
    Florida Big Bend to near Tampico, Mexico. The front is followed
    by fresh to near gale-force NW to N winds and rough seas per
    recent buoy and platform observations, and earlier ASCAT
    scatterometer data, along with building and rough seas. Frequent
    gusts to gale force are expected across the coastal waters of the
    NE Gulf, particularly between Apalachicola, FL and Mobile, AL
    through much of today. Conditions will improve across the Gulf
    region Thu night into the weekend. A reinforcing surge of fresh to
    strong northerly winds may impact the basin late in the weekend,
    potentially developing northerly gale-force winds near Tampico and
    Veracruz on Sun.

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

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough enters the Atlantic along the coast of Sierra
    Leone near 08N13W, then runs southwestward to 08N15W. The ITCZ
    extends from 04N12W to 02N30W to 03N49W. Scattered moderate
    convection is noted on conventional satellite imagery from 00N to
    02N between 14W and 20W, and from 01.5N to 04N between 21W and 26.5W.

    ...GULF OF MEXICO...

    A Gale Warning for frequent gusts to gale force is in effect for
    the coastal waters of the NE Gulf. Please, read the Special
    Features section for more details.

    As mentioned, a cold front extends from the Florida Big Bend to
    near Tampico, Mexico. The front is followed by fresh to near
    gale-force NW to N winds and rough seas per recent buoy and
    platform observations, and earlier ASCAT scatterometer data, along
    with building and rough seas. Multilayer clouds, with possible
    showers, are noted over most of the Gulf waters and Florida.
    Mainly moderate SW-W winds with a pre-frontal trough are noted
    across the remainder of the basin ahead of the front.

    For the forecast, a cold front from the Florida Big Bend to near
    Tampico, Mexico will move rapidly across the basin, shifting
    southeast of the area by this evening. The front is followed by
    increasing winds and building seas. Conditions will improve from
    NW to SE tonight into the weekend. A reinforcing front and surge
    of fresh to strong northerly winds may impact the basin this weekend.

    ...CARIBBEAN SEA...

    Fresh to strong winds over the south-central Caribbean early this
    morning, along with 5 to 7 ft seas. Moderate to fresh winds are
    noted over the remainder of the east and central parts of the
    basin S of 20N. Light to gentle winds and slight to moderate seas
    dominate the western Caribbean, except in the far NW Caribbean
    where a pre-frontal trough reaches from the western tip of Cuba to
    the Gulf of Honduras with moderate NW winds to the W of it. Some
    shower activity is observed near the trough. Elsewhere, patches of
    low level moisture, with possible showers, prevail.

    For the forecast, winds will pulse to fresh to strong winds
    offshore of NW Colombia early this morning, then return Fri night
    through the weekend and into early next week. Elsewhere, moderate
    or weaker winds will prevail through early today, except moderate
    to fresh across the remainder of the central Caribbean S of 20N. A
    cold front will move into the NW Caribbean later today, stall
    from E Cuba to Honduras on Fri, and dissipate on Sat. The pressure
    gradient may tighten in the wake of the front later in the
    upcoming weekend and early next week leading to increasing winds
    and building seas across the basin, while a reinforcing front and
    surge of winds also arrives in the NW Caribbean by early Mon.

    ...ATLANTIC OCEAN...

    Please read the Special Features section about an upcoming Gale Warning.

    A cold front extends from 31N73W to the Straits of Florida where
    it has stalled, with fresh to strong winds on either side N of 27N
    and W of 68W. Scattered showers and thunderstorms are flaring up
    near this boundary. Fresh to strong winds are N of 27N and W of
    68W, along with locally rough seas, mainly N of 30N.

    High pressure dominates the remainder of the tropical Atlantic
    forecast region. Under the influence of this system, an area of
    fresh to strong NE winds is noted from 12N to 26N and E of 35W to
    the coast of W Africa, including near the Cabo Verde Islands.
    Seas of 7 to 10 ft are within these winds. Moderate to locally
    fresh trades are observed across the tropical Atlantic with
    moderate to rough seas. Gentle to moderate winds and mainly
    moderate seas are elsewhere. An upper-level low in the central
    Atlantic near 23N38W is triggering some shower activity, while
    moist southerly flow in the wake of a warm front now well N of 31N
    supports additional shower activity N of 27N between 46W and 60W.

    For the forecast west of 55W, a reinforcing front will move off
    Florida later this morning and merge with the leading front,
    reaching from near Bermuda to the SE Bahamas Fri morning, and
    extending from 31N59W to 25N70W Sat morning where it will stall
    and weaken. Widespread fresh to strong winds will accompany the
    front through Fri. Winds are forecast to reach gale force Thu
    night east of the front and N of 29N. Another cold front may
    impact the basin late in the upcoming weekend.
