    Areas affected...Eastern North Carolina and southeast Virginia

    Concerning...Severe Thunderstorm Watch 466...

    Valid 091757Z - 091930Z

    The severe weather threat for Severe Thunderstorm Watch 466
    continues.

    SUMMARY...A line of storms producing damaging winds will persist
    through the afternoon.

    DISCUSSION...A well-developed squall line across central North
    Carolina continues east. Sporadic wind damage reports have been
    received, but measured wind gusts have remained below 40 knots. This
    is likely related to relatively warm cold pool temperatures within
    the moist environment. Given the warm and moist downstream
    environment (temperatures around 90F and mid-70s dewpoints), expect
    this squall line to continue east through the afternoon. Sporadic
    damaging wind gusts will remain possible with storm scale processes
    and stronger downbursts likely responsible for more concentrated
    areas of wind damage.
