    DISCUSSION AND OUTLOOK
    ----------------------
    At 400 AM CDT (0900 UTC), the center of Tropical Depression
    Claudette was located near latitude 33.3 North, longitude 85.8 West.
    The depression is moving toward the east-northeast near 13 mph (20
    km/h). On the forecast track, the system should cross portions of
    the southeast U.S. through tonight, move over the coasts of
    North Carolina into the western Atlantic Ocean on Monday, and be
    located south of Nova Scotia by late Tuesday.

    Maximum sustained winds remain near 30 mph (45 km/h) with higher
    gusts. Some re-strengthening is expected by late today, and
    Claudette is expected to become a tropical storm again on Monday
    over eastern North Carolina. Further strengthening is possible
    over the western Atlantic Ocean through early Tuesday. Claudette
    is expected to become a post-tropical cyclone by late Tuesday.

    The estimated minimum central pressure from surface observations is
    1006 mb (29.71 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Claudette can be found in the Tropical Cyclone
    Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC,
    and on the web at http://www.hurricanes.gov .

    RAINFALL: Claudette is expected to produce additional rainfall
    totals of 1 to 3 inches with isolated maximum amounts of 6 inches
    across Alabama, the Florida Panhandle, northern and central Georgia,
    and Upstate South Carolina through the morning hours. As the system
    tracks north and east, bands of heavy rain will occur across
    portions of central and southern Georgia, central and coastal South
    Carolina into eastern North Carolina through Monday morning
    resulting in rainfall totals of 2 to 4 inches with isolated maximum
    amounts of 8 inches. Considerable flash, urban and small stream
    flooding impacts, as well as new and renewed minor to isolated
    moderate river flooding are possible across these areas.

    Storm total rainfall of 5 to 10 inches with isolated 15 inch amounts
    was observed in southeast Louisiana, southern Mississippi, southern
    Alabama, and the western Florida panhandle.

    For the latest rainfall reports and wind gusts associated with
    Claudette, see the companion storm summary at WBCSCCNS3 with the
    WMO header ACUS43 KWBC or at the following link: https://www.wpc.ncep.noaa.gov/discussions/nfdscc3.html .

    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 if
    the peak surge occurs at the time of high tide...

    NC/VA Border to Cape Lookout, NC...1-3 ft
    Cape Lookout, NC to Little River Inlet, SC...1-2 ft

    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.

    WIND: Tropical storm conditions are expected to begin in
    the warning area late tonight or early Monday. Tropical storm
    conditions are possible in the watch area tonight and Monday.

    TORNADOES: A few tornadoes are possible today across parts of
    Georgia and the Carolinas.
