    A Hurricane Warning means that hurricane conditions are expected
    somewhere within the warning area. A warning is typically issued
    36 hours before the anticipated first occurrence of
    tropical-storm-force winds, conditions that make outside
    preparations difficult or dangerous. Preparations to protect life
    and property should be complete.

    A Hurricane Watch means that hurricane conditions are possible
    within the watch area.

    A Tropical Storm Warning means that tropical storm conditions are
    expected somewhere within the warning area within 36 hours.

    Interests elsewhere in Haiti, the Dominican Republic, Cuba, the
    southeastern and central Bahamas, and the Turks and Caicos Islands
    should monitor the progress of Melissa.

    For storm information specific to your area, please monitor
    products issued by your national meteorological service.


    DISCUSSION AND OUTLOOK
    ----------------------
    At 200 AM EDT (0600 UTC), the center of Hurricane Melissa was
    located near latitude 16.3 North, longitude 76.1 West. Melissa is
    moving toward the west-southwest near 5 mph (7 km/h). A slow
    westward motion is expected through tonight, followed by a turn to
    the north and northeast on Monday and Tuesday. On the forecast
    track, the center of Melissa is expected to move near or over
    Jamaica through Tuesday, and it could be near or over eastern Cuba
    by the middle of the week.

    Data from an Air Force Reserve Hurricane Hunter aircraft indicate
    that maximum sustained winds are near 120 mph (195 km/h) with higher
    gusts. Melissa is a category 3 hurricane on the Saffir-Simpson
    Hurricane Wind Scale. Continued rapid intensification is forecast
    during the next day or so, followed by fluctuations in intensity.
    Melissa is expected to be a major hurricane when making landfall in
    Jamaica Monday night or Tuesday.

    Hurricane-force winds extend outward up to 25 miles (35 km) from
    the center and tropical-storm-force winds extend outward up to 160
    miles (260 km).

    The estimated minimum central pressure based on dropsonde data is
    958 mb (28.29 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Melissa can be found in the Tropical Cyclone
    Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

    WIND: Tropical storm conditions are likely beginning in Jamaica,
    with hurricane conditions expected by Monday. Tropical storm
    conditions are expected in the warning area in Haiti today. The
    potential for hurricane conditions in the watch area in Haiti
    have diminished for today, but there is still a possibility of
    hurricane conditions occurring there on Tuesday. Hurricane
    conditions are possible in the watch area in eastern Cuba on Tuesday
    into Wednesday.

    RAINFALL: Melissa is expected to bring total rainfall of 15 to 30
    inches to portions of southern Hispaniola and Jamaica into
    Wednesday, with local maxima of 40 inches possible. Additional
    heavy rainfall is likely beyond Wednesday; uncertainty at that time
    range precludes exact storm totals. Catastrophic flash flooding and
    landslides are probable across portions of southern Hispaniola and
    Jamaica.

    For eastern Cuba, total rainfall of 6 to 12 inches, with local
    amounts to 18 inches, are expected into Wednesday resulting in
    life-threatening flash flooding and landslides. Additional heavy
    rainfall is likely beyond Wednesday; uncertainty at that time range
    precludes exact storm totals.

    For a complete depiction of forecast rainfall associated with
    Melissa, please see the National Weather Service Storm Total
    Rainfall Graphic, available at
    hurricanes.gov/graphics_at3.shtml?rainqpf

    STORM SURGE: Life-threatening storm surge is becoming more likely
    along the south coast of Jamaica during the next few days. Peak
    storm surge heights could reach 9 to 13 feet above ground level,
    near and to the east of where the center of Melissa makes landfall.
    This storm surge will be accompanied by large and destructive waves.

    There is a potential for significant storm surge along the
    southeast coast of Cuba late Tuesday or Wednesday.

    SURF: Swells generated by Melissa are expected to affect portions
    of Hispaniola, Jamaica, eastern Cuba, and the Cayman Islands during
    the next several days. Please consult products from your local
    weather office.
