    Areas affected...portions of northern Florida and southeast Georgia

    Concerning...Tornado Watch 9...

    Valid 040136Z - 040330Z

    The severe weather threat for Tornado Watch 9 continues.

    SUMMARY...The threat for a tornado and locally damaging winds
    continues across locally-extended Tornado Watch 8 and southern
    portions of Tornado Watch 9. Current indications are that a a new
    downstream watch will not be needed.

    DISCUSSION...A line of severe thunderstorms with embedded/transient
    low-level circulations was located from Colquitt County, GA south to
    Gulf County, FL at 0130Z. Several TDS signatures have been noted
    with circulations along this line in the past two hours, and a
    continued risk for tornadoes will exist through 03-04Z across the
    eastern FL panhandle/Big Bend given 0-1 km SRH in excess of 300
    m2/s2. As the evening progresses, this line of storms will move
    into an environment where earlier mixing has lowered dew points, and
    increasing CINH should lead to a weakening trend. Although an
    isolated risk for damaging winds and possibly a brief tornado will
    exist east and south of the current watch areas, the overall trend
    is such that a downstream watch is not anticipated.
