    Areas affected...eastern South Carolina...southeastern North

    Concerning...Tornado Watch 347...

    Valid 080538Z - 080745Z

    The severe weather threat for Tornado Watch 347 continues.

    SUMMARY...Tornado risk continues east and northeast of the center of
    Tropical Storm Elsa. As risk spreads northeastward with time, a new
    tornado watch will be required (within the next 1/2 hour or so).

    DISCUSSION...Latest radar loop shows several small/rotating cells --
    mainly embedded within the primary convective band which is now
    beginning to shift into the Charleston metro area. This band is
    currently advancing northward at around 25 kt -- which will place
    this band near the northern fringe of the watch by 0630Z -- about an
    hour from now. With the latest VWP from the KCLX WSR-88d showing
    low-level flow veering rapidly with height yielding 35-40 kt 0-1km
    shear, and dewpoints well into the mid to upper 70s across the
    coastal tier or two of counties, expect low-level rotation -- and
    potential for occasional tornadic spin-ups -- to continue over the
    next several hours. A new WW will be required -- that will extend
    northward into southeastern North Carolina.
