    ...SPECIAL FEATURES...

    Western Atlantic Gale Warning: A slow-moving cold front extends
    from 31N72W to a 1009 mb low pressure centered near 29N73W to the
    Florida Straits. The front will drift slowly eastward, before
    stalling into the weekend from just E of Bermuda to eastern Cuba.
    The low will move NE along the boundary and lift N of the area
    near Bermuda Thu night. Thunderstorms with gusty winds will impact
    waters along and east of the cold front through at least Thu. The
    pressure gradient between strong high pressure to the north and
    the front is supporting NE gales offshore NE Florida, mainly N of
    28N and W of 72W. These gales will continue through tonight before
    gradually diminishing as the low pressure weakens and begins to
    move N of the region. Very rough seas have been generated by these
    gales, and seas of up to 20 ft are forecast in the gale area
    today into tonight. The very rough seas will linger across
    portions of the waters N of the Bahamas into Thu night, with rough
    seas in N swell impacting much of the waters N of 25N into the
    weekend. With the stationary front lingering over the basin
    through the weekend, NE winds W of the boundary will be slow to
    diminish through the period.

    East Atlantic Large Swell: Long period NW to N swell continues to
    propagating through portions of the far eastern Atlantic, causing
    seas of 12 to 14 ft N of 19N and E of 39W. Rough seas cover a much
    broader area, N of 10N and E of 55W. The swell will only very
    slowly decay, and seas of 12 ft or greater will reach as far as
    15N by Thu. Seas should fall below 12 ft Thu night, although rough
    seas will likely persist into the weekend.

    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 on
    both the West Atlantic Gale Warning and the Significant Swell in
    the East Atlantic.

    East Atlantic Gale Warning: Meteo-France has issued a Gale
    Warning for the forecast zone of Madeira. The forecast calls for
    NW gales to 40 kt, with severe gusts from 08/12 UTC to 09/00 UTC
    at least. Very rough seas in NW swell are also reaching the islands.

    For more details, refer to the Meteo- France High Seas Forecast
    listed on their website https://wwmiws.wmo.int .

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough enters the Atlantic near 07N11W and continues
    SW to 02N21W. The ITCZ extends west-southwestward from 02N21W to
    00N44W. Scattered moderate convection is from 03S to 07N between 05W and 38W.

    ...GULF OF MEXICO...

    A slow-moving cold front extends from the Florida Keys to a 1010
    mb low pressure centered near 24N85W to just N of the Yucatan
    Channel. ENE winds gradually increase N of this boundary, becoming
    strong in the NE Gulf, where seas are rough. in the western Gulf,
    mainly gentle NE winds and moderate seas prevail. A cluster of
    moderate convection has developed early this morning within 90 nm
    of the coast of Tampico, Mexico, otherwise no thunderstorms are
    present in the Gulf.

    For the forecast, the cold front will drift slowly E and out of
    the basin by Thu, keeping strong to near gale-force NE winds and
    rough seas in place over the NE Gulf into Thu. As high pressure
    builds SW into the northern Gulf Fri through the weekend, moderate
    to fresh E to SE winds will establish through the basin.

    ...CARIBBEAN SEA...

    The Atlantic ridge extends SW reaching the NE Caribbean. This
    system is supporting fresh to locally strong E to SE winds and
    seas of 6 to 8 ft across the eastern part of the basin. Gentle to
    moderate NE to E winds and 3 to 5 ft seas are ongoing across the
    SW Caribbean while light and variable winds and slight seas
    dominate the NW Caribbean. Scattered moderate convection is noted
    between Jamaica, eastern Cuba, and Haiti, in association with a
    trough to the north.

    For the forecast, fresh to strong trades will prevail over the
    central and eastern basin into Thu, with gentle to moderate winds
    to the west. Strong high pressure will then build southward from
    the western Atlantic, with a tightening pressure gradient leading
    to increasing winds, especially in the south-central basin.

    ...ATLANTIC OCEAN...

    A Gale Warning is in effect for the portions of the western
    Atlantic. A Gale Warning has also been issued by Meteo-France for
    portions of the far eastern Atlantic. Please refer to the Special
    Features section for details.

    Aside from the cold front that is inducing the gales, a low
    pressure trough along 68W from 31N southward to about 22W is
    leading to fresh to strong S winds N of 26N between the trough
    axis and 60W. The trough and cold front are leading to numerous
    moderate to scattered strong convection extending northward from
    Hispaniola and eastern Cuba between 65W and 75W.

    E of 65W, broad northeast to east winds dominate the basin. Most
    areas are having moderate to fresh breezes, but a zone of strong
    easterly extend N of 20N and E of 40W, where some significant
    northerly swell is leading to very rough seas. Details on the
    swell and its forecast propagation can be found in the Special
    Features section above. Moderate seas dominate the remainder of the Atlantic.

    For the forecast west of 55W, please refer to the Special Features
    Western Atlantic Gale Warning section for forecast details
    related to the marine conditions caused by the previously
    mentioned frontal boundary.
