    ...WATERSPOUTS POSSIBLE ACROSS THE SOUTH CAROLINA NEARSHORE WATERS THIS MORNING...

    The environment across the nearshore Atlantic waters of South
    Carolina will be suitable for waterspout formation this morning.
    The waterspout risk will be greatest near lines of towering clouds
    and in the vicinity of showers and thunderstorms. Conditions
    will become less favorable for waterspouts by late this morning as
    a sea breeze develops.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    If waterspouts occur, move your boat away from the waterspout.
    Remember that waterspouts can develop rapidly and produce winds
    and seas that are dangerous for vessels and everyone onboard.

    Report waterspouts via social media or by calling the National
    Weather Service at 1-888-383-2024.
