    expected somewhere within the warning area within 36 hours.

    Interests elsewhere in Haiti, the Dominican Republic, and Cuba
    should monitor the progress of Melissa. A hurricane warning may be

    products issued by your national meteorological service.


    DISCUSSION AND OUTLOOK
    ----------------------
    At 800 PM EDT (0000 UTC), the center of Tropical Storm Melissa was
    located near latitude 16.0 North, longitude 75.5 West. Melissa is
    moving toward the north near 2 mph (4 km/h). A slow northward or north-northeastward motion is forecast during the next day or so,
    followed by a sharp turn westward over the weekend. On the forecast
    track, Melissa is expected to move closer to Jamaica and the
    southwestern portion of Haiti during the next couple of days.

    Maximum sustained winds are near 45 mph (75 km/h) with higher
    gusts. Gradual strengthening is forecast over the next day or so,
    followed by rapid intensification this weekend. Melissa is
    forecast to become a hurricane by Saturday and a major hurricane by
    the end of the weekend.

    Tropical-storm-force winds extend outward up to 140 miles (220 km)
    from the center.

    The minimum central pressure estimated from NOAA Hurricane Hunter
    aircraft data is 1000 mb (29.53 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: Hurricane conditions are possible within the watch area in
    Haiti and Jamaica beginning on late Friday or Saturday. Tropical
    storm conditions are expected to begin in Haiti and Jamaica earlier
    on Friday.

    RAINFALL: Melissa is expected to bring 8 to 14 inches of rain to the
    southern Dominican Republic, southern Haiti, and eastern Jamaica
    through Sunday, with locally higher amounts possible. Additional
    heavy rainfall is likely beyond Sunday; however, uncertainty in
    Melissa's track and forward speed reduces confidence in exact
    totals. Significant, life-threatening flash flooding and numerous
    landslides are expected in the southern Dominican Republic and
    eastern Jamaica, with catastrophic flash flooding and landslides
    anticipated in southern Haiti.

    Across the northern Dominican Republic, northern Haiti, and western
    Jamaica, 2 to 4 inches of rain is expected through Sunday. Flash and
    urban flooding will be possible through Sunday. Flooding impacts may
    increase across western Jamaica next week.

    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: Minor coastal flooding is likely along the coast of
    Jamaica by late Friday into Saturday in areas of onshore winds as
    tropical storm conditions begin to reach the area. However, there
    is a potential risk of a more significant storm surge, especially
    along the south coast of Jamaica, early next week. Due to Melissa's
    slow motion and large forecast uncertainty, it is still too soon to
    know exactly how high the storm surge could reach.

    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.
