    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 in Jamaica and rushed to completion
    in Cuba.

    A Hurricane Watch means that hurricane conditions are possible
    within the watch area. A watch is typically issued 48 hours
    before the anticipated first occurrence of tropical-storm-force
    winds, conditions that make outside preparations difficult or
    dangerous.

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

    A Hurricane Warning may be required for portions of the Bahamas and
    the Turks and Caicos islands later today or tonight. Interests in
    Bermuda should also 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 1100 AM EDT (1500 UTC), the center of Hurricane Melissa was
    located near latitude 16.4 North, longitude 78.2 West. Melissa is
    moving toward the west near 3 mph (6 km/h). A slow turn toward the
    northwest and north is expected later today, followed by a turn
    toward the northeast and a faster forward speed on Tuesday. A
    northeastward motion is expected on Wednesday and Thursday. On the
    forecast track, the core of Melissa is expected to move over Jamaica
    tonight and early Tuesday, across southeastern Cuba Tuesday night,
    and across the southeastern Bahamas on Wednesday.

    Maximum sustained winds are near 165 mph (270 km/h) with higher
    gusts. Melissa is a category 5 hurricane on the Saffir-Simpson
    Hurricane Wind Scale. Some fluctuations in intensity are likely
    before Melissa makes landfall on Jamaica on Tuesday. However,
    Melissa is expected to reach Jamaica and southeastern Cuba as an
    extremely powerful major hurricane, and will still be at hurricane
    strength when it moves across the southeastern Bahamas.

    Hurricane-force winds extend outward up to 30 miles (45 km) from the
    center and tropical-storm-force winds extend outward up to 195 miles
    (315 km).

    The minimum central pressure estimated from the latest Air Force
    Reserve Hurricane Hunter aircraft data is 908 mb (26.82 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 occurring in Jamaica, and
    catastrophic and life-threatening hurricane-force wind conditions
    are expected to begin tonight and continue into early Tuesday.
    Within the eyewall, total structural failure is likely, especially
    in higher elevation areas where wind speeds atop and on the windward
    sides of hills and mountains could be up to 30 percent stronger.

    Tropical storm conditions are expected to begin in eastern Cuba on
    Tuesday, with hurricane conditions expected to begin in the
    hurricane warning area by Tuesday evening. Tropical storm conditions
    are expected in Haiti late Tuesday and Wednesday.

    Tropical storm and hurricane conditions are possible in the
    southeastern and central Bahamas, as well as the Turks and Caicos
    Islands, on Wednesday.

    RAINFALL: Melissa is expected to bring rainfall of 15 to 30 inches
    to portions of Jamaica and additional rainfall of 8 to 16 inches for
    southern Hispaniola through Wednesday, with storm total local maxima
    of 40 inches possible. Catastrophic flash flooding and numerous
    landslides are likely.

    For eastern Cuba, storm total rainfall of 15 to 20 inches, with
    local higher amounts, is expected by Monday into Wednesday resulting
    in life-threatening and potentially catastrophic flash flooding with
    numerous landslides.

    Over the Southeast Bahamas, total rainfall of 4 to 8 inches is
    expected Tuesday into Wednesday resulting in areas of flash
    flooding.

    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: A life-threatening storm surge is likely along the
    south coast of Jamaica tonight and on Tuesday. 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. Peak storm surge heights
    could reach 7 to 11 feet above normal tide levels, near and to the
    east of where the center of Melissa makes landfall. This storm surge
    will be accompanied by large and destructive waves.

    Storm surge of 4 to 6 ft above normally dry ground is possible in
    the southeastern Bahamas and Turks and Caicos Islands on 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, and the Bahamas, the Turks and Caicos Islands,
    and Bermuda later this week. These swells are likely to cause
    life-threatening surf and rip current conditions. Please consult
    products from your local weather office.
