    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Tue Mar 3 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 0930 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 to 13 ft. The swell has propagated
    from this source region, with the very rough seas currently over
    the waters from 12N to 21N between 36W and 53W. These seas will
    gradually subside from east to west through tonight. Rough seas
    are then forecast to subside E of the Lesser Antilles this weekend.

    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 near 05N08W to 02N11W. The
    ITCZ extends from that point to 03S26W to the coast of Brazil
    near 03S40W. Scattered moderate convection is ongoing from 03S to
    06N between 05W and 45W.

    ...GULF OF MEXICO...

    A weak surface trough is analyzed in the NE Gulf along 87W with
    little convection near it. Surface ridging dominates elsewhere
    and supports moderate to fresh E winds E of 87W, and moderate or
    weaker winds elsewhere. Seas are mainly slight basin-wide.

    For the forecast, high pressure will extend from the N central
    Atlantic southwestward across the region through the week, with
    the resultant pressure gradient supporting moderate to fresh east
    to southeast winds across the Gulf, except in the Bay of Campeche
    where winds will be mostly moderate northeast to east. Fresh to
    strong winds will occur nocturnally off the northern Yucatan
    Peninsula starting today.

    ...CARIBBEAN SEA...

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

    Surface ridging from strong high pressure centered N of the area
    is supporting fresh to near-gale winds over the eastern and
    central Caribbean, and moderate to fresh NE winds in the lee side
    of Cuba and the Windward Passage. Seas in the regions of highest
    winds are moderate, except for rough seas in the south-central and
    SE Caribbean.

    For the forecast, a broad area of high pressure over the central
    Atlantic will support fresh to near gale-force trades along with
    moderate to rough seas across the central and eastern Caribbean
    through Sat night. Winds off Colombia will pulse to gale-force
    during the nocturnal hours through the weekend. Fresh to strong
    northeast winds in the Windward Passage and in the lee of Cuba
    will continue to pulse through the forecast period. In the Gulf of
    Honduras, fresh to strong winds will begin to pulse at night from
    Thu through Sat. Elsewhere, rough to very rough seas in wind
    generated east swell over the tropical N Atlantic will begin to
    slowly subside on Thu.

    ...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 continues 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 26N.
    Over the E Atlantic subtropical waters, the passage of a cold
    front is bringing strong to near gale-force N to NW winds to the
    waters just N of the Canary Islands. Long period NW swell is
    supporting very rough seas to 15 ft within this area of very
    strong winds. Lastly, a stationary front extends from 31N56W
    southwestward to 24N69W being followed by strong NE to E winds
    and rough seas to 11 ft extending westward toward 74W. Scattered
    showers and thunderstorms prevail along and E of the front to about 55W.

    For the forecast west of 55W, the stationary front will become
    diffuse by this evening. Fresh to strong northeast to east winds
    along with rough to very rough seas behind the front will diminish
    tonight. However, seas will linger into Wed while expanding
    southeastward and merging with similar seas south of 25N east of
    Bahamas. Otherwise, strong high pressure will become centered over
    the western N Atlantic through the next few days. It will be the
    main feature controlling the general flow wind pattern across the
    region, with fresh to strong east winds confined to mostly south of 25N.

    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    1215 UTC Thu Mar 5 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 1020 UTC.

    ...SPECIAL FEATURES...

    Caribbean Sea Gale Warning: The tight pressure gradient between
    a well established high pressure ridge over the northwestern
    Atlantic and low pressure over NW Colombia will continue to
    support fresh to near gale-force NE to E winds, and rough to very
    rough seas across much of the central and southwestern Caribbean
    Sea through the middle or next week. Winds offshore of Colombia
    are expected to pulse to gale-force overnight through Sat night.

    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 near 07N12W and extends to
    04N16W. The ITCZ extends from 04N16W to 00N30W to the coast of
    Brazil near 02S45W. Scattered moderate convection is noted from
    00N to 06N between 16W and 30W. Scattered to numerous moderate to
    strong convection is from 02S to 03N W of 34W.

    ...GULF OF MEXICO...

    Broad surface ridging extends from the central Atlantic westward
    into the Gulf, which is providing moderate to fresh E to SE winds
    across the eastern half of the basin, and moderate or weaker
    winds W of 90W. Seas basin-wide are slight to moderate. Otherwise,
    oil rigs platforms as well as buoy data are reporting dense fog
    over the NW Gulf with visibility less than 2 nm.

    For the forecast, Atlantic high pressure will extend a broad ridge southwestward into the Gulf through early next week, thus
    supporting mainly moderate to fresh E to SE winds basin-wide. Seas
    will be slight to moderate through the forecast period.

    ...CARIBBEAN SEA...

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

    The pressure difference between high pressure well north of the
    area and the NW Colombia low pressure maintains fresh to strong
    trades across much of the central and eastern Caribbean. Moderate
    to fresh trades prevail elsewhere. Rough seas are analyzed in the
    central and portions of the SW Caribbean, with moderate seas in
    the eastern Caribbean and slight to moderate seas prevailing in
    the NW basin.

    For the forecast, a ridge of high pressure will prevail N of the
    area into the weekend. The pressure gradient between the ridge and
    the Colombian low will support fresh to near gale-force trades
    across the central and eastern Caribbean through Mon. Winds
    offshore of Colombia will pulse to gale-force during the overnight
    hours through Sat night while fresh to strong NE winds in the
    Windward Passage and in the lee of Cuba will pulse through early
    Sat evening. In the Gulf of Honduras, fresh to strong winds will
    pulse at night today through Sun night. Otherwise, rough seas in
    easterly trade wind swell over the tropical N Atlantic will
    continue through Tue.

    ...ATLANTIC OCEAN...

    A 1037 mb high near 40N30W extends a ridge across much of the
    Atlantic, also supported by a 1027 mb high near 33N65W. As a
    result, fresh to strong trades and rough seas cover much of the
    Atlantic between the west coast of Africa and 55W between the
    Equator and 27N. Moderate to fresh trades and moderate to rough
    seas prevail between 55W and the southern Bahamas to the S of
    27N. Otherwise, moderate or weaker winds and slight to moderate
    seas prevail elsewhere.

    For the forecast west of 55W, moderate to fresh easterly winds
    will prevail S of 25N through Mon night, reaching strong speeds N
    of Hispaniola into the Windward passage. Rough seas will prevail
    within these winds and E of the central and southern Bahamas
    through Tue. Otherwise, moderate or weaker winds can be expected
    elsewhere across the region.
