    Areas affected...coastal and near coastal counties of Georgia and
    South Carolina.

    Concerning...Severe potential...Tornado Watch likely=20

    Valid 051849Z - 052015Z

    Probability of Watch Issuance...95 percent

    SUMMARY...A new tornado watch will be needed later this afternoon in
    coastal areas across eastern Georgia and eastern South Carolina.

    DISCUSSION...Instability has mostly struggled to move inland within
    the northeastern quadrant of Tropical Storm Debby where persistent
    stratiform rain has been present all day. A push of higher moisture
    content and greater instability is advancing toward the
    Georgia/South Carolina coast. This may result in a greater threat
    for cellular convection and stronger updrafts late this afternoon
    and this evening. Any storms which can develop would pose a tornado
    threat given the favorable wind shear sampled by the JAX VWP. In
    addition, the low-level hodograph is starting to elongate at CLX,
    with this increasing low-level shear expected to advance up the
    coast this evening and into the overnight hours. With tornado watch
    596 expiring at 20Z, a new tornado watch will be issued for portions
    of coastal South Carolina and parts of Coastal Georgia.
