    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...

    South-Central Caribbean Gale Warning:
    A tight pressure gradient between high pressure SE of Bermuda and
    lower pressure over northwest Colombia is supporting gale force
    ENE winds offshore Colombia near Barranquilla early this morning,
    along with seas of up to 11 ft (3.5 m). The gradient will relax
    later today as the high pressure moves farther east, allowing
    gales to end.

    Please read the latest High Seas and Offshore Waters Forecasts
    issued by the National Hurricane Center at website: ttps://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and https://www.nhc.noaa.gov/marine/offshores.php
    for more details on these events.

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough enters the Atlantic near the coastal border of
    Guinea and Sierra Leone near 09N23W, then continues to 02N22W.
    The ITCZ continues from 02N22W to 00N32W. Scattered moderate to
    strong convection is evident from 00N to 02N between 29W and 32W.

    ...GULF OF MEXICO...

    A nearly stationary front resides along the northern Gulf coast
    from the Florida Panhandle to Deep South Texas. South of this
    boundary, a 1025 mb high pressure centered near 26N92W is
    dominating the weather over the basin. A generally light,
    anticyclonic flow is established over the basin, except for gentle
    NE winds in the eastern Bay of Campeche. Seas are 3 ft or less.

    For the forecast, high pressure will remain in control of the
    weather pattern across the Gulf waters through Fri, bringing light
    to gentle SE winds. Southerly winds will increase to moderate to
    fresh speeds Fri night ahead of a cold front that will moves cross
    the west and central waters Sat night and Sun. Strong winds and
    rough seas are possible in the northern Gulf with this frontal system.

    ...CARIBBEAN SEA...

    See the Special Features section above on a Gale Warning.

    A surface trough that extends along 68W through the Mona Passage
    is leading to scattered moderate convection within 120 nm south of
    Puerto Rico. Otherwise, dry conditions prevail, with moderate to
    fresh trades across most of the basin, with the except of the NW,
    where gentle to moderate NE to E winds are ongoing. Seas are 5 to
    7 ft in the central and eastern basin, 5 to 9 ft in the SW, and 3
    to 5 ft in the NW.

    For the forecast, gale-force winds will end early this morning
    offshore Colombia, but will pulse to near gale-force again tonight
    due to the pressure gradient between the Colombia/Panamanian low
    and high pressure centered N of the region. Winds will continue to
    pulse to strong nightly thereafter. Elsewhere, moderate to fresh
    trades will prevail through the weekend.

    ...ATLANTIC OCEAN...

    Large NW swell over the central Atlantic continues to decay this
    morning and seas have now fallen below 12 ft. Still, the long-
    period-swell is leading to widespread rough seas of 8-11 ft for
    all waters E of 60W. Across the same area, S of 25N, moderate to
    fresh trades dominate. A dissipating cold stationary front from
    31N31W to 25N45W separates two high pressure centers that are
    providing waters N of 25N with mainly gentle winds.

    Waters W of 60W and S of 25N are being dominated by ridging
    associated with the western high pressure, centered near 30N50W
    with 1022 mb. This is inducing gentle winds above moderate seas. N
    of 25N, SW winds have increased to strong ahead of a cold front
    that is sagging southward to just N of the area. Already rough
    seas in this area of strong winds continue to build.

    For the forecast west of 55W, the cold front will enter NW waters
    this morning. Ahead of the front, strong SW to W winds will
    prevail N of 28N, along with rough to very rough seas. These
    hazardous conditions will spread east through tonight, then
    diminish Fri as the front weakens. By Fri night the cold front
    will extend from near 31N55W to the SE Bahamas, and the boundary
    will sag SE and out of the area Sat night. On Sun, S winds will
    increase to strong offshore Florida, in advance of another cold
    front that will move off the SE U.S. coast Mon.

    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Mon Mar 2 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 0900 UTC.

    ...SPECIAL FEATURES...

    Caribbean Sea Gale Warning: The pressure gradient between high
    pressure N of the area and the Colombian low will continue to
    support strong to near gale-force NE to E winds and rough to very
    rough seas across the south-central and portions of the SW
    Caribbean through at least Sat. Winds will pulse to gale-force
    over these waters at night with the added component of nocturnal
    drainage flow.

    Central and Eastern Atlantic Significant Swell Event: A previous
    gale force wind event off the Canary Islands generated a large NE
    swell with very rough seas greater than 12 ft. The swell has
    propagated from this source region, with these very rough seas
    currently over the waters from 09N to 23N between 33W and 52W.
    The seas, currently peaking near 12 ft will gradually subside from
    east to west through Tue night while rough seas to 10 ft are
    forecast to subside E of the Lesser Antilles late on Sun.

    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 off the coast of Africa
    near 09N13W and continues southwestward to 02N18W. The ITCZ
    extends from that point to the coast of Brazil near 02S40W.
    Scattered to numerous moderate convection is noted within 360 nm
    on either side of the boundaries.

    ...GULF OF MEXICO...

    The tail of a weakening stationary front extends across the
    Straits of Florida to the SE Gulf near 25N87W while a broad
    surface ridge prevails elsewhere. Winds N of 23N are moderate to
    locally fresh from the E to SE over the NW Gulf. Seas are mainly
    slight to 3 ft basin-wide.

    For the forecast, the tail of the weakening stationary front will
    dissipate over the SE Gulf today. Afterward, an expansive area of
    strong high pressure will build WSW from the central N Atlantic
    and hold through the weekend. Its related pressure gradient will
    support moderate to fresh E to SE winds across the Gulf. Locally
    strong winds will occur at night off the northern Yucatan
    Peninsula starting Tue.

    ...CARIBBEAN SEA...

    Please see Special Features section above regarding a Gale Warning
    in the south-central Caribbean.

    Surface ridging from strong high pressure over the E CONUS and
    also the Azores High extends across the northern Caribbean, thus
    supporting the continuation of fresh to strong winds over the
    eastern and central Caribbean, and moderate to fresh NE winds in
    the lee side of Cuba. Seas in the regions of highest winds are
    moderate, except rough offshore Colombia and slight seas over the NW Caribbean.

    For the forecast, the subtropical ridge over the central Atlantic
    will support fresh to near gale-force trades and moderate to
    rough seas across the central and eastern Caribbean through Fri
    night. A tighter pressure gradient will initiate gale-force winds
    off Colombia at night beginning tonight and continuing through at
    least Sat. Fresh to strong NE winds will also begin in the
    Windward Passage and the lee side of Cuba this evening and will
    continue through Fri. In the Gulf of Honduras, fresh to strong E
    winds will begin to pulse at night from Thu through Sat.
    Otherwise, rough to very rough seas in mixed NE to E swell over
    the tropical N Atlantic will subside on Sun.

    ...ATLANTIC OCEAN...

    Please see Special Features above for information on a significant swell event.

    A strong Azores high extending a ridge into the deep tropical
    waters continue to support a broad area of fresh to strong NE to E
    winds and rough to very rough seas from the coast of W Africa all
    the way to the Lesser Antilles and between the ITCZ and 27N.
    Northwest of the Canary Islands, a cold front brings fresh to
    strong N to NE winds and rough seas in NW swell. Lastly, a weak
    stationary front extends from Bermuda to the northern Bahamas.
    Scattered showers and thunderstorms prevail ahead of the front
    and a pre-frontal trough to about 60W. Moderate NE winds and seas
    follow the front.

    For the forecast west of 55W, the stationary front will weaken
    further as it slowly moves southeastward before becoming diffuse
    tonight. Elsewhere, high pressure over the central Atlantic will
    prevail over much of the western Atlantic while rough seas will
    continue over the southeastern waters. Fresh to strong NE to E
    winds and rough to very rough seas are forecast behind the
    remnants of the aforementioned front through Tue night north of
    27N. An expansive area of strong high pressure will build across
    the north-central Atlantic by the middle of the week resulting in
    moderate to fresh winds and rough seas over much of the basin.
