    DISCUSSION AND OUTLOOK
    ----------------------
    At 800 AM AST (1200 UTC), the center of Tropical Storm Fiona was
    located by an Air Force Reserve reconnaissance aircraft near
    latitude 16.1 North, longitude 63.4 West. Fiona is moving toward
    the west near 13 mph (20 km/h). A westward to west-northwestward
    motion with a decrease in forward speed is expected through Sunday
    night. A turn toward the northwest is forecast early next week. On
    the forecast track, the center of Fiona is expected to move near or
    just south of the Virgin Islands and Puerto Rico today through
    Sunday, and approach the southern or eastern coast of the Dominican
    Republic Sunday night and Monday.

    Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
    Some strengthening is forecast, and Fiona could be at or near
    hurricane strength when it moves near Puerto Rico and the Dominican
    Republic over the weekend.

    Tropical-storm-force winds extend outward up to 125 miles (205 km)
    from the center.

    Data from the Air Force Reserve Hurricane Hunter aircraft indicate
    that the minimum central pressure is 1000 mb (29.53 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Tropical Storm Fiona can be found in the Tropical
    Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header
    WTNT42 KNHC and on the web at hurricanes.gov/text/MIATCDAT2.shtml.

    WIND: Hurricane conditions are possible on Puerto Rico late
    tonight or on Sunday, and within the hurricane watch area in the
    Dominican Republic late Sunday through Monday.

    Tropical storm conditions will continue across portions of the
    Leeward Islands within the warning area through this morning.
    Tropical storm conditions will reach the U.S. and British Virgin
    Islands later this morning, spread westward across Puerto Rico this
    afternoon and tonight, and reach portions of the Dominican Republic
    on Sunday. Tropical storm conditions are possible across the watch
    area in the Dominican Republic beginning Sunday afternoon.

    RAINFALL: Fiona is forecast to produce the following rainfall:

    Leeward Islands and Northern Windward Islands: Additional 2 to 4
    inches.

    British and U.S. Virgin Islands: 4 to 6 inches with local 10 inches
    possible.

    Puerto Rico: 5 to 10 inches with local 16 inches possible,
    particularly across eastern and southern Puerto Rico.

    Dominican Republic: 4 to 8 inches with 12 inches possible,
    particularly on the far eastern coast.

    Haiti: 1 to 3 inches with isolated maximum totals of 4 inches.

    Turks and Caicos: 4 to 10 inches.

    These rains are likely to produce flash and urban flooding, along
    with mudslides in areas of higher terrain, particularly in southern
    and eastern Puerto Rico and the eastern Dominican Republic.

    STORM SURGE: The combination of storm surge and the tide will cause
    normally dry areas near the coast to be flooded by rising waters
    moving inland from the shoreline. The water could reach the
    following heights above ground somewhere in the indicated areas
    in areas of onshore winds if the peak surge occurs at the time of
    high tide...

    Southern coast of Puerto Rico...1 to 3 ft

    Localized coastal flooding is also possible elsewhere in Puerto Rico
    and the U.S. Virgin Islands. For information specific to your area,
    please see products issued by your local National Weather Service
    forecast office.

    Storm surge will raise water levels by as much as 1 to 3 feet above
    normal tide levels along the immediate coast in areas of onshore
    winds in the Dominican Republic.

    SURF: Swells generated by Fiona are affecting the Leeward Islands,
    the northern Windward Islands, the Virgin Islands, and Puerto Rico.
    Swells will spread westward to the northern coast of Hispaniola, the
    Turks and Caicos Islands, and the southeastern Bahamas over the
    weekend. These conditions could cause life-threatening surf and rip
    current conditions. Please consult products from your local weather
    office.
