    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Sun Mar 1 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 0925 UTC.

    ...SPECIAL FEATURES...

    Caribbean Sea Gale Warning: A broad subtropical ridge over the
    central Atlantic will support strong to near gale-force easterly
    trade winds and rough seas across the south-central Caribbean during
    the next several days. A tighter pressure gradient will initiate
    gale-force winds off Colombia at night starting Mon and continue
    through at least next weekend. Locally very rough seas are expected
    with these winds.

    Central and Eastern Atlantic Significant Swell Event: A strong high
    pressure of 1033 mb located SW of the Azores near 33N38W is
    maintaining fresh to strong winds across much of the eastern and
    central Atlantic. Wind waves associated with these winds will
    continue to generate seas of 8 to 14 ft across most of the waters
    between 20W and 60W, with highest seas E of 50W. This swell event
    will persist through early next week.

    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 through the coast of
    Guinea-Bissau near 12N16W and continues southwestward to 04N18W.
    The ITCZ extends from 04N18W to the coast of Brazil near 04S38W.
    Scattered to numerous moderate to strong convection is observed
    south of 08N and between Africa and 44W.

    ...GULF OF MEXICO...

    A weak stationary front extends across the SE Gulf waters,
    producing a few showers ahead of this boundary. The weak pressure
    gradient across the basin supports moderate or weaker winds and
    slight to moderate seas.

    For the forecast, the storm activity will continue southeastward
    across the far SE Gulf this morning. The stationary front will
    transition to a weakening cold front this morning, slowly move
    southeastward and exit the basin. Afterward, a strong high
    pressure system will build west- southwestward over the area from
    the N Atlantic beginning tonight, with the related gradient
    generally supporting moderate to fresh east to southeast winds
    across the Gulf. Locally strong winds will occur at night off the
    northern Yucatan Peninsula starting Tue.

    ...CARIBBEAN SEA...

    A broad high pressure over the central Atlantic extends into the
    Caribbean Sea, supporting strong to near gale-force easterly winds
    and rough seas in the south-central Caribbean. Fresh to strong
    easterly breezes and rough seas are found in the SE Caribbean.
    Rough seas are noted in the Atlantic passages of the Lesser
    Antilles. Moderate to fresh easterly winds and moderate seas are
    evident in the rest of the central and eastern Caribbean.
    Elsewhere, moderate or weaker winds and slight to moderate seas prevail.

    For the forecast, a broad subtropical ridge over the central Atlantic
    will support fresh to near gale-force easterly trades and moderate
    to rough seas across the central and eastern Caribbean through the
    forecast period. A tighter pressure gradient will initiate gale-
    force winds off Colombia at night Mon through at least late this
    week and support locally very rough seas. Fresh to strong
    northeast winds will begin in the Windward Passage starting late
    Mon night. 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 cold front extends southwestward from 31N74W to SE Florida. A
    band of showers with embedded strong thunderstorms is ahead of the
    front between 67W-78W. A strong high pressure of 1033 mb situated
    SW of the Azores near 33N38W extends a ridge across the remainder
    of the Atlantic forecast waters. This system is maintaining fresh
    to strong winds across much of the eastern and central Atlantic,
    particularly E of 60W, with rough seas. Moderate to fresh E to SE
    winds and moderate seas are noted on the western periphery of the
    ridge. Elsewhere, moderate or weaker winds and moderate seas are prevalent.

    For the forecast west of 55W, the front will slowly move southeastward
    reaching from near 31N69W to the central Bahamas tonight and from
    31N62W to the SE Bahamas Mon morning as it weakens. 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 this week and gradually shift southeastward and weaken.
    Fresh to near gale- force easterly winds and rough to very rough
    seas, peaking to around 13 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.

    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.
