    Special Tropical Weather Outlook
    NWS National Hurricane Center Miami FL
    715 PM EDT Tue May 22 2018

    For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

    A broad surface low centered just east of Belize is producing a
    large area of cloudiness and showers extending from the northwestern
    Caribbean Sea across Cuba and into the Florida peninsula. Little
    development is expected during the next couple of days due to strong
    upper-level winds and proximity to the Yucatan Peninsula of Mexico.
    However, gradual subtropical or tropical development is possible
    late this week while the system moves slowly into the central or
    eastern Gulf of Mexico. Regardless of development, locally heavy
    rainfall is possible across western Cuba, the Cayman Islands, and
    much of Florida during the next several days. For more information
    on the heavy rain threat, please see products issued by your local
    weather office. The next Special Tropical Weather Outlook on this
    system will be issued by 800 AM EDT on Wednesday.
    * Formation chance through 48 hours...low...near 0 percent.
    * Formation chance through 5 days...medium...50 percent.

    Tropical Weather Discussion
    NWS National Hurricane Center Miami FL
    128 AM EDT Wed May 23 2018

    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 32N. The following information is based on satellite
    imagery, weather observations, radar and meteorological analysis.

    Based on 0000 UTC surface analysis and satellite imagery through
    0515 UTC.

    ...SPECIAL FEATURES...

    A 1007 mb low pressure center is near 18N87W. A surface trough
    extends from the NE Yucatan Peninsula near 22N87W to the low
    center to the N coast of Honduras near 16N86W. This system just
    east of Belize is producing a large area of cloudiness and showers
    extending from the northwestern Caribbean Sea across Cuba and
    into the Florida peninsula. Little development is expected during
    the next couple of days due to strong upper-level winds and
    proximity to the Yucatan Peninsula of Mexico. However, gradual
    subtropical or tropical development is possible late this week
    while the system moves slowly into the central or eastern Gulf of
    Mexico. Regardless of development, locally heavy rainfall is
    possible across western Cuba, the Cayman Islands, and much of
    Florida during the next several days. For more information on the
    heavy rain threat, please see products issued by your local
    weather office. There is a very low possibility of tropical storm
    formation over the next 24 hours. There is a medium chance for
    tropical formation within 5 days.

    ...TROPICAL WAVES...

    A tropical wave is along 41W, S of 10N, moving W at 10 to 15
    knots. This wave is embedded in a sharp 700 mb trough. Scattered
    showers are within 120 nm of the wave axis.

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough passes through the coastal sections of Guinea near
    11N15W to 04N18W. The ITCZ continues from 04N18W to 01N30W to
    02N40W. The ITCZ resumes W of the tropical wave near 02N43W and
    reaches the coast of Brazil near 00N50W. Isolated moderate
    convection is from 00N-04N between 02W-22W. Similar convection is
    from 05S-03N between 23W-30W. Scattered moderate to isolated
    strong convection is along the coast of Brazil from 02S-01N
    between 46W-51W.

    ...DISCUSSION

    GULF OF MEXICO...

    10-15 kt E to SE surface return flow is over the Gulf of Mexico.
    Presently scattered showers are over portions of the Florida
    Peninsula, the Straits of Florida, and W Cuba.

    An upper level trough is in place over the far E Gulf of Mexico
    and Florida. Upper level diffluence is E of the trough axis, over
    the W Atlantic. A second upper level trough has entered the NW
    Gulf. An upper level ridge is over the central Gulf in between the
    two troughs.

    An Atlantic surface ridge extending into the northern Gulf of
    Mexico will shift eastward through Fri. An area of low pressure
    is expected to develop off the northern coast of Yucatan on Fri.
    The tropical low will move slowly northward in the eastern Gulf
    this weekend, with highest winds and seas east of the low.

    CARIBBEAN SEA...

    Please read the Special Features section above. Clusters of
    scattered moderate convection is inland over Central America from
    the Yucatan Peninsula to Panama. An area of scattered moderate
    convection is S of Cuba from 16N-22N between 77W-83W.

    An upper level ridge is over the W Caribbean W of 70W with
    considerable upper level moisture. An upper level trough is over
    the E Caribbean with strong subsidence E of 70W and N of 12N.

    A surface ridge north of the area will maintain fresh trade
    winds in the central Caribbean through Thu, with strong winds
    expected along the northern coast of Colombia. A broad low near
    Belize will drift northward into the Gulf of Mexico through Fri.
    Fresh to strong SE winds and building seas are possible in the NW
    Caribbean Thu night and Fri as the low develops.

    ATLANTIC OCEAN...

    Scattered showers are over the W Atlantic W of 74W to include the
    Bahamas and Florida. A 1027 mb high is centered over the central
    Atlantic near 31N50W producing fair weather.

    An E-to-W oriented ridge along 30N will support moderate to fresh
    trade winds south of 22N this week, with winds pulsing to strong
    N of Hispaniola at night. Winds and seas will diminish slightly
    Fri as the ridge shifts east. An area of low pressure in the
    Gulf of Mexico will increase SE winds west of 77W this weekend.
