    SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

    A Tropical Storm Warning is in effect for...
    * Edisto Beach to South Santee River South Carolina

    A Tropical Storm Warning means that tropical storm conditions are
    expected somewhere within the warning area, in this case within the
    next 12 hours.

    For storm information specific to your area, including possible
    inland watches and warnings, please monitor products issued by your
    local National Weather Service forecast office.


    DISCUSSION AND OUTLOOK
    ----------------------
    At 1100 AM EDT (1500 UTC), the center of Tropical Depression Four
    was located near latitude 31.9 North, longitude 78.3 West. The
    depression is moving toward the west-northwest near 16 mph (26 km/h)
    and this general motion is expected to continue for the next couple
    of days. On the forecast track, the center of the tropical cyclone
    should make landfall along coast of South Carolina in the warning
    area later this evening.

    Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
    Some slight strengthening is expected today, and the depression is
    forecast to become a tropical storm before it makes landfall. Rapid
    weakening is forecast after landfall occurs.

    The estimated minimum central pressure is 1013 mb (29.92 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    WIND: Tropical storm conditions are expected to first reach
    the coast within the warning area by late this afternoon, making
    outside preparations difficult or dangerous.

    RAINFALL: The depression could produce 1 to 3 inches of rainfall
    with locally higher amounts along the immediate coasts of Georgia
    and southern South Carolina. This region has been dry, limiting
    potential widespread flooding impacts, however, local flooding
    impacts, especially in urban areas along the southern South Carolina
    and Georgia coasts, cannot be ruled out at this time.

    Farther inland, 1 to 2 inches of rainfall is possible across Upstate
    South Carolina, the Piedmont of Georgia, and into northeastern
    Alabama.

    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...

    Port Royal Sound, SC to South Santee River, SC...1 to 3 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.
