The Saffir-Simpson Hurricane Scale is a classification used for most Western Hemisphere tropical cyclones that exceed the intensities of "tropical depressions" and "tropical storms", and thereby become hurricanes. Source: Intellicast

    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 0600 UTC surface analysis and satellite imagery through
    1045 UTC.

    ...SPECIAL FEATURES...
    Please refer to the METEO-FRANCE High Seas Forecast, that is
    listed under the following links: MARINE...BULLETINS
    EXPERTISES...GRAND LARGE...METAREA II...or on the website:
    WWW.METEOFRANCE.COM/PREVISIONS-METEO-MARINE/BULLETIN/
    GRANDLARGE/METAREA2. Gale-force winds are forecast for the area
    that is called: AGADIR.

    ...TROPICAL WAVES...

    An Atlantic Ocean tropical wave is along 30W/31W from 18N
    southward. This position is based on satellite imagery.
    Convective precipitation: isolated moderate to locally strong
    from 03N to 17N beween 27W and 36W.

    An Atlantic Ocean tropical wave is along 18N39W 13N42W 07N45W.
    Convective precipitation: isolated moderate from 10N to 13N
    between 35W and 40W. scattered strong within 45 nm on either side
    of 11N43W 10N46W 08N47W.

    An Atlantic Ocean tropical wave is along 59W/60W from 23N
    southward. Convective precipitation: isolated moderate to locally
    strong from 14N to 24N between 57W and 65W.

    A Caribbean Sea tropical wave is along 71W/72W from 20N in the
    central sections of the Dominican Republic to NW Venezuela.
    Convective precipitation: widely scattered moderate to isolated
    strong from 16N to 20N between 68W and 77W. rainshowers are
    possible from 20N to 23N between 67W and 75W.

    A Caribbean Sea tropical wave is along 87W/88W, from 18N
    southward. This wave cuts across parts of Honduras and El
    Salvador, into the eastern Pacific Ocean. Convective
    precipitation: rainshowers are possible within 60 nm on either
    side of the tropical wave.

    ...ITCZ/MONSOON TROUGH...

    The Monsoon Trough passes through the coastal sections of Senegal
    near 14N17W, to 13N28W, to 12N39W. The ITCZ continues from 09N45W
    to 08N50W and 08N55W. Convective precipitation: scattered strong
    from 05N to 10N between 49W and 54W.

    ...DISCUSSION...

    ...THE GULF OF MEXICO...

    An upper level cyclonic circulation center is about 60 nm to the
    S of SE Louisiana. Cyclonic wind flow covers the Gulf of Mexico
    from 24N northward. A second cyclonic circulation center is about
    150 nm to the NW of the NW corner of the Yucatan Peninsula.
    Convective precipitation: isolated to widely scattered moderate
    from 24N northward. scattered moderate to isolated strong from 19N
    to 20N between 94W and 96W. earlier precipitation that was in
    Mexico, from the Yucatan Peninsula to the Isthmus of Tehuantepec,
    has weakened leaving convective debris clouds.

    A surface ridge extends from Lake Okeechobee in south Florida,
    into the central sections of the Gulf of Mexico, to 25N94W, into
    NE Mexico.

    A thermal trough is along 92W/93W from 22N southward.

    ...CURRENT CONDITIONS AND WEATHER, FOR THE OFFSHORE OIL PLATFORM
    SITES, THAT ARE IN THE AREA WHOSE BOUNDARIES ARE FROM 27N
    NORTHWARD AND FROM 88W WESTWARD, and FOR THE COASTAL PLAINS OF
    THE U.S.A., FROM THE DEEP SOUTH OF TEXAS TO FLORIDA...

    Convective precipitation: isolated to widely scattered moderate
    from 24N northward. scattered moderate to isolated strong from 19N
    to 20N between 94W and 96W.

    ...THE CARIBBEAN SEA...

    Upper level cyclonic wind flow covers the Caribbean Sea from 16N
    northward between the Mona Passage and NW Cuba. A tropical wave is
    along 71W/72W. Convective precipitation: widely scattered moderate
    to isolated strong from 16N to 20N between 68W and 77W.
    rainshowers are possible from 20N to 23N between 67W and 75W.

    Upper level anticyclonic wind flow covers the area from Central
    America into the NW corner of the Caribbean Sea, to Jamaica,
    including in the SW corner of the Caribbean Sea.

    Middle level to upper level anticyclonic wind flow covers the
    easternmost part of the area, to the E and SE of the trough/
    cyclonic wind flow.

    Convective precipitation: numerous strong in the Gulf of Uraba of
    Colombia, within a 30 nm radius of 09N77W. rainshowers are
    possible from 11N southward from 80W westward.

    24-hour rainfall totals in inches, for the period that ended at
    22/0000 UTC, according to the PAN AMERICAN TEMPERATURE AND
    PRECIPITATION TABLES...MIATPTPAN/SXCA01 KNHC...are: 0.13 in
    Guadeloupe, and 0.01 in Tegucigalpa in Honduras.

    ...HISPANIOLA...

    Hispaniola is on the eastern side of an upper level trough.
    The trough extends from the Atlantic Ocean near 27N76W. Upper
    level southerly wind flow is moving across the area.

    A Caribbean Sea tropical wave is along 71W/72W from 20N in the
    central sections of the Dominican Republic to NW Venezuela.
    Convective precipitation: widely scattered moderate to isolated
    strong from 16N to 20N between 68W and 77W. rainshowers are
    possible from 20N to 23N between 67W and 75W.

    SURFACE OBSERVATIONS...for Port-au-Prince in Haiti: VFR. for the
    DOMINICAN REPUBLIC: Barahona: VFR. few cumulonimbus clouds. Santo
    Domingo: nearby rainshowers. few cumulonimbus clouds. La Romana:
    VFR. Punta Cana: VFR. Santiago: MVFR. ceiling 1600 feet. Puerto
    Plata: VFR. few cumulonimbus clouds.

    The GFS MODEL forecast for 250 mb shows that the current trough
    will last for another 12 hours or so. An Atlantic Ocean-to-
    Hispaniola ridge will bring anticyclonic wind flow to the area for
    the rest of the 48-hour forecast period. The GFS MODEL forecast
    for 500 mb shows that Hispaniola will be on the southern side of
    an Atlantic Ocean ridge. Larger-scale anticyclonic wind flow will
    be interspersed with a few inverted troughs, during the next 48
    hours. The GFS MODEL forecast for 700 mb shows that E-to-SE wind
    flow will move across the area, with Hispaniola on the southern
    side of an Atlantic Ocean ridge.

    ...THE ATLANTIC OCEAN...

    A western Atlantic Ocean upper level cyclonic circulation center
    is about 225 nm to the east of SE Florida. The cyclonic wind flow
    that surrounds the cyclonic center covers the Atlantic Ocean and
    the Bahamas, and parts of Cuba and Hispaniola. Convective
    precipitation: Rainshowers are possible from 22N northward between
    67W and interior sections of Florida, and also in the coastal
    waters of Florida in the Gulf of Mexico.

    An upper level cyclonic circulation center and associated trough
    are about 1700 nm to the west of southern Morocco. Convective
    precipitation: isolated moderate from 20N northward between 37W
    and 50W.

    A surface ridge passes through 32N39W, to 29N45W, to a 1023 mb
    high pressure center that is near 28N57W, to 27N73W. into the
    central Gulf of Mexico.
