    Areas affected...Portions of the Mid-Atlantic Coastal States

    Concerning...Severe Thunderstorm Watch 474...

    Valid 092306Z - 100030Z

    The severe weather threat for Severe Thunderstorm Watch 474
    continues.

    SUMMARY...The threat for damaging winds continues across WW 474 as a
    line of strong to severe thunderstorms moves eastward, and
    eventually, offshore. Thunderstorm wind gusts of 55-70 MPH remain
    possible.

    DISCUSSION...Linear convection within WW 474 continues to move
    east-southeast across the Mid-Atlantic coastal states and will
    continue to pose a hazard for damaging straight-line wind gusts.
    Sufficient buoyancy and deep-layer shear will continue to support
    linear bowing segments before ultimately moving offshore into the
    Atlantic. The best short-term corridor for damaging wind gusts
    appears to be across portions of Virginia and Maryland, where the
    combination of MLCAPE and deep-layer shear is best maximized and
    current radar trends suggest the strongest updrafts have developed.
