    during the next 36 hours in the indicated locations. For a
    depiction of areas at risk, please see the National Weather

    hurricanes.gov. This is a life-threatening situation. Persons
    located within these areas should take all necessary actions to
    protect life and property from rising water and the potential for
    other dangerous conditions. Promptly follow evacuation and other
    instructions from local officials.

    A Storm Surge Watch means there is a possibility of life-
    threatening inundation, from rising water moving inland from the
    coastline, in the indicated locations during the next 48 hours.

    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.

    DISCUSSION AND OUTLOOK
    ----------------------
    At 1100 AM EDT (1500 UTC), reports from An Air Force Reserve
    reconnaissance aircraft indicate that the center of the eye of
    Hurricane Florence was located near latitude 29.8 North, longitude
    71.3 West. Florence is now moving toward the northwest near 15 mph
    (24 km/h) and this general motion, accompanied by a gradual
    decrease in forward speed, is expected to through Saturday. On the
    forecast track, the center of Florence will move over the
    southwestern Atlantic Ocean between Bermuda and the Bahamas today,
    and approach the coast of North Carolina or South Carolina in the
    hurricane warning area on Thursday and Friday and move slowly near
    the coastline through Saturday.

    The reconnaissance aircraft found that maximum sustained winds
    remain near 130 mph (215 km/h) with higher gusts. Florence is a
    category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.
    Some strengthening is forecast through tonight. While some
    weakening is expected to begin by late Thursday, Florence is still
    forecast to be an extremely dangerous major hurricane when it nears
    the U.S. coast on Friday.

    Hurricane-force winds extend outward up to 70 miles (110 km) from
    the center and tropical-storm-force winds extend outward up to 175
    miles (280 km).

    The estimated minimum central pressure is 943 mb (27.85 inches).





    HAZARDS AFFECTING LAND
    ----------------------
    STORM SURGE: The combination of a dangerous 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 has the
    potential to reach the following heights above ground if peak surge
    occurs at the time of high tide...

    Cape Fear NC to Cape Lookout NC, including the Neuse, Pamlico,
    Pungo, and Bay Rivers...9-13 ft
    North Myrtle Beach SC to Cape Fear NC...6-9 ft
    Cape Lookout NC to Ocracoke Inlet NC...6-9 ft
    South Santee River SC to North Myrtle Beach SC...4-6 ft
    Ocracoke Inlet NC to Salvo NC...4-6 ft
    Salvo NC to North Carolina/Virginia Border...2-4 ft
    Edisto Beach SC to South Santee River SC...2-4 ft

    The deepest water will occur along the immediate coast in areas of
    onshore winds, where the surge will be accompanied by large and
    destructive waves. Surge-related flooding depends on the relative
    timing of the surge and the tidal cycle, and can vary greatly over
    short distances. For information specific to your area, please see
    products issued by your local National Weather Service forecast
    office.

    RAINFALL: Florence is expected to produce heavy and excessive
    rainfall in the following areas...

    Coastal North Carolina...20 to 30 inches, isolated 40 inches. This
    rainfall would produce catastrophic flash flooding and significant
    river flooding.

    South Carolina, western and northern North Carolina...5 to 10
    inches, isolated 20 inches.
    Elsewhere in the Appalachians and Mid-Atlantic states...3 to 6
    inches, isolated 12 inches.

    WIND: Hurricane conditions are expected to reach the coast within
    the hurricane warning area late Thursday or Friday. Winds are
    expected to first reach tropical storm strength on Thursday, making
    outside preparations difficult or dangerous. Preparations to
    protect life and property should be rushed to completion.

    TORNADOES: A few tornadoes are possible in eastern North Carolina
    beginning late Thursday morning.

    SURF: Swells generated by Florence are affecting Bermuda and
    portions of the U.S. East Coast. These swells are likely to cause
    life-threatening surf and rip current conditions. Please consult
    products from your local weather office.
