    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
    0530 UTC.


    Caribbean Sea Gale Warning: A tight surface pressure gradient
    continues to exist, between comparatively higher surface pressures
    in the western Atlantic Ocean, and lower surface pressures in
    northern sections of South America. This pattern is supporting
    winds reaching gale-force strength from 10N to 13.5N between 73W
    and 77.5W. Wave heights within the area of gale-force winds will
    range from 10 feet to 16 feet. Please read the latest NHC High
    Seas Forecast under AWIPS/WMO headers MIAHSFAT2/FZNT02 KNHC for
    more details.


    The monsoon trough passes through coastal sections of Sierra Leone
    near 08N13W, to 05N17W. The ITCZ continues from 05N17W, crossing
    the Equator along 22W, to 02N30W, to 01S38W. Precipitation:
    scattered moderate to strong rainshowers are from 01N to the coast
    of Africa between 04W and 07W, and from 02N southward between 47W
    and 49W. scattered moderate to isolated strong rainshowers are
    from 02N southward between 16W and 21W, and from 02N southward
    between 40W and 42W. isolated moderate to locally strong
    rainshowers are elsewhere from 10N southward from 60W eastward.
    Upper level SW wind flow is to the south of the line 23N16W 20N30W
    18N40W 14N50W 11N58W.



    Upper level SW wind flow is moving from southern Mexico, across
    Texas and Louisiana and the Gulf of Mexico that is from 92W
    westward. Broad upper level anticyclonic wind flow spans the rest
    of the area. Isolated moderate rainshowers are in Mexico from 20N
    to 22N between the coast and 99W, and in Texas from 30N southward,
    and mainly in the middle Texas coastal plains at the moment.

    A surface ridge extends from the NE corner of the Gulf of Mexico,
    southwestward, to the coast of Mexico near 21N97W.

    Strong surface high pressure across the W Atlantic Ocean will
    persist, with a ridge extending W across the U.S.A. Gulf coast
    states, in order to produce fresh return flow across most of the
    basin, except for strong winds through the Straits of Florida and
    across central sections of the Gulf. A weak cold front will move
    slowly into the far NW waters on Sunday, and stall there on Sunday


    Please read the SPECIAL FEATURES section for details about the
    Gale Warning for the waters that are near the coast of Colombia.

    A surface ridge passes across central Cuba, to 19N82W in the NW
    corner of the area, to southern Costa Rica.

    Rainshowers are possible, in areas of broken-to-overcast low
    level clouds, across the entire area. 24-hour rainfall totals
    that are listed for the period that ended at 21/0000 UTC...
    TABLES...MIATPTPAN/SXCA01 KNHC...are: 0.50 in Guadeloupe, and
    0.05 in Curacao.

    Surface high pressure across the NW Atlantic Ocean will build S
    across the region through Wednesday, and then settle across the
    Bermuda area through the end of the week. Fresh-to-strong trade
    winds will prevail across the Caribbean Sea and the Tropical N
    Atlantic waters through Thursday, with nocturnal winds pulsing to
    gale-force off the coast of Colombia. High pressure will weaken
    through the weekend, leading to diminishing winds and seas.


    An upper level trough passes through 32N34W to 28N36W 24N48W, to
    19N60W. A cold front passes through 32N30W, to 23N40W and 21N53W.
    A dissipating cold front continues from 21N53W to 21N62W. Broken
    to overcast low level clouds and possible rainshowers are to the
    NW and N of the line that passes through 32N27W 22N40W 18N60W

    A surface ridge passes through 32N68W, beyond central Cuba, into
    the NW corner of the Caribbean Sea.

    A W Atlantic Ocean ridge will persist along 33N-34N through
    Thursday, and then it will drift SW, and slowly weaken through the
    weekend. Gentle-to-moderate winds will prevail N of 25N, with
    fresh-to-strong winds S of 25N through Thursday. NNE swell will
    move through the waters E of 65W through Friday night.
