    SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

    * Jamaica

    A Hurricane Watch is in effect for...
    * Southwestern peninsula of Haiti from the border with the
    Dominican Republic to Port-Au-Prince

    A Tropical Storm Warning in effect for...

    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 rushed to completion.

    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, eastern Cuba,
    the southeastern and central Bahamas, and the Turks and Caicos
    Islands should monitor the progress of Melissa. Watches could be
    required for portions of eastern Cuba later today.

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


    DISCUSSION AND OUTLOOK
    ----------------------
    At 200 PM EDT (1800 UTC), the center of Hurricane Melissa was
    located near latitude 16.6 North, longitude 75.2 West. Melissa is
    moving slowly toward the west-northwest near 1 mph (2 km/h). A slow west-northwestward or westward motion is expected today through
    the end of the weekend. A turn to the north and northeast is
    forecast on Monday and Tuesday. On the forecast track, the center of
    Melissa is expected to move near or over Jamaica during the weekend
    and early next week, and it could be near or over eastern Cuba by
    the middle of next week.

    Maximum sustained winds have increased to near 75 mph (120 km/h)
    with higher gusts. Rapid intensification is forecast to occur over
    the next couple of days and Melissa is forecast to become a major
    hurricane by Sunday.

    Hurricane-force winds extend outward up to 35 miles (55 km) from
    the center and tropical-storm-force winds extend outward up to 125
    miles (205 km).

    The estimated minimum central pressure is 980 mb (28.94 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 expected to begin in Jamaica by
    tonight, with hurricane conditions expected by Sunday or Monday.
    Tropical storm conditions are expected and hurricane conditions are
    possible within the watch and warning area in Haiti later today.

    RAINFALL: Melissa is expected to bring total rainfall of 15 to 25
    inches to portions of southern Hispaniola and Jamaica into
    Wednesday, with local maxima of 35 inches possible across eastern
    Jamaica and the Tiburon Peninsula of Haiti. Additional heavy
    rainfall is likely beyond Wednesday but exact storm totals are still
    uncertain. Catastrophic flash flooding and landslides are expected
    across southwestern Haiti and portions of Jamaica, with the
    possibility of catastrophic flood impacts also extending across the
    remainder of southern Haiti into southern Dominican Republic.

    For eastern Cuba, total rainfall of 5 to 10 inches, with local
    amounts to 15 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 later in the weekend or early next
    week. Peak storm surge heights could reach 7 to 11 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 early next week.

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