    The government of Jamaica has issued a Tropical Storm Watch for the

    A Hurricane Watch is in effect for...
    * Border with Dominican Republic to Port-Au-Prince

    A Tropical Storm Watch is in effect for...
    * Jamaica

    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 Watch means that tropical storm conditions are
    possible within the watch area, generally within 48 hours.

    Interests elsewhere in Haiti, the Dominican Republic, and Cuba
    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 1100 AM EDT (1500 UTC), the center of the newly formed Tropical
    Storm Melissa was located near latitude 14.3 North, longitude 71.7
    West. Melissa is moving toward the west near 14 mph (22 km/h). A
    decrease in forward speed and a gradual turn to the northwest and
    north is expected during the next few days. On the forecast track,
    Melissa is expected to approach the southwestern portion of Haiti
    and Jamaica later this week.

    Surface observations and satellite data indicate that the maximum
    sustained winds are near 50 mph (85 km/h) with higher gusts. Gradual strengthening is expected during the next few days.

    Tropical-storm-force winds extend outward up to 115 miles (185 km)
    from the center.

    The estimated minimum central pressure is 1003 mb (29.62 inches).


    HAZARDS AFFECTING LAND

    Key messages for Tropical Storm 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 beginning on Thursday. Tropical storm conditions could begin
    in Jamaica on Thursday or Friday.

    RAINFALL: Melissa will bring heavy rainfall to Haiti and the
    Dominican Republic, with totals of 5 to 10 inches expected through
    Friday. Additional heavy rainfall is possible beyond Friday, but
    uncertainty regarding the track and forward speed of Melissa
    reduces confidence in exact amounts. Areas of significant flash
    flooding and mudslides are possible.

    Over Aruba, Puerto Rico and Jamaica rainfall of 1 to 3 inches is
    expected through Friday. Flash and urban flooding will be possible
    across Puerto Rico through at least Friday.

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