    Tropical Weather Discussion for North America, Central America
    Gulf of America, 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 1200 UTC surface analysis and satellite imagery through
    1530 UTC.

    ...SPECIAL FEATURE...

    Caribbean Gale Warning: A tight pressure gradient between high
    pressure north of the basin and the Colombian low will support
    fresh to strong NE-E winds in the south-central Caribbean during
    the next several days. Winds will pulse to gale-force across the
    waters N of Colombia each night through Sat night. Rough to very
    rough seas will prevail with these winds.

    issued by the National Hurricane Center at website - https://urldefense.com/v3/__https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml__;!!DZ3fjg!6FkKDLf3pr8QmaVz0MPyQ2uUZXRSoDjUPj_gSNdZFCsxoIUInBLOSGRLmj0MqEl4mV8oMl7u4Qk3s7u987Ro75OeTuU$ for more details.

    ...TROPICAL WAVES...

    An eastern Atlantic tropical wave is analyzed along 22W, south of
    16N, moving westward at 5-10 kt. Scattered moderate convection is
    present from 11N to 13N and between 20W and 23W and remains
    disorganized. Some slow development is possible during the next
    couple of days while the system moves generally west-northwestward
    at about 10 mph. By this weekend, the system is forecast to move
    into a less conducive environment, and further development is not
    expected. The disturbance has a low chance of development over the
    next 7 days.

    An eastern Atlantic tropical wave is along 35W, south of 18N,
    moving westward at 15-20 kt. No significant convection is noted
    with this wave at this time.

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough enters the Atlantic through the coast of
    Africa near 21N17W and continues southwestward to a 1012 mb low
    pres near 11N22W to 09N33W. The ITCZ extends from 09N40W to
    08N60W. Scattered moderate convection is present from 11N to 13N
    and between 20W and 23W

    ...GULF OF AMERICA...

    A 1021 mb high pressure system positioned over the northern Gulf
    near 28N88W. A surface trough is analyzed over the Yucatan
    Peninsula. The pattern is supporting moderate to fresh winds
    across the southwest and south-central Gulf, where seas are 3-5
    ft. Gentle to moderate breeze are noted elsewhere over the
    western Gulf, with 2-4 ft seas. Light to gentle breezes are noted
    over the north- central and northeast Gulf with 1-3 ft seas. A few
    showers and thunderstorms are active off Tampa Bay, Florida, and
    Tampico, Mexico.

    For the forecast, fresh to strong winds will pulse offshore the
    Yucatan Peninsula each night. Gentle to moderate winds, and
    slight to moderate seas, will prevail elsewhere.

    Looking ahead, an area of low pressure is forecast to form this
    weekend over the northeastern Gulf of America. Some gradual
    development of this system is possible while it moves slowly
    northeastward over the northeastern Gulf and near the coast of the
    southeastern United States early next week.

    ...CARIBBEAN SEA...

    A Gale Warning is in effect for the south-central Caribbean offshore
    of Colombia. Please refer to the Special Features section for
    more details.

    The Atlantic subtropical ridge centered north of the Caribbean
    forces strong to gale easterly trade winds across the central
    Caribbean, with the strongest winds occurring off Colombia and in
    the Gulf of Venezuela. Rough to very rough seas are found in these
    waters. Fresh NE winds and moderate seas are noted in the
    Windward Passage and Gulf of Honduras. Meanwhile, moderate to
    fresh easterly winds and moderate seas are present in the eastern
    Caribbean. Elsewhere, moderate or weaker winds and slight to
    moderate seas are prevalent.

    A diffluent pattern aloft combined with abundant tropical moisture
    is generating a large area of showers and thunderstorms over the
    Gulf of Honduras. Trade wind convergence is supporting showers and thunderstorms off western Panama. Gusty winds, frequent
    lightning, and higher seas are likely with this convective
    activity.

    For the forecast, the pressure gradient between high pressure north of
    the basin and the Colombian low will support pulsing NE winds to
    gale-force across the waters N of Colombia each night through
    Sat night. Otherwise, strong to near-gale trade winds and rough
    seas will prevail across the central Caribbean into early next
    week. East winds will pulse fresh to strong each evening in the
    Gulf of Honduras and Windward Passage.

    ...ATLANTIC OCEAN...

    A broad ridge extends across the Atlantic basin north of 15N,
    anchored by 1025 mb centered near 30N40W. In addition to the
    tropical waves south of the ridge, a weak surface trough extends
    from the Leeward Islands to 21N55W. Another weak trough reaches
    from the northern Bahamas to 31N75W, supporting showers and
    thunderstorms near 30N75W. Gentle to moderate NE to E winds and
    3-5 ft seas is noted along the ridge axis north of 15N and west of
    35W, and moderate to fresh NE to E winds and 4-6 ft are noted
    elsewhere.

    For the forecast west of 55W, the ridge will remain dominant through
    the forecast period. The weather pattern will support moderate
    to fresh trades south of 25N, with gentle winds to the north.
    Pulsing strong winds are expected each night offshore Hispaniola
    and in the Windward Passage.
