    Areas affected...western FL Panhandle...southeast AL...southwest GA

    Concerning...Tornado Watch 285...

    Valid 192322Z - 200045Z

    The severe weather threat for Tornado Watch 285 continues.

    SUMMARY...The risk for a few tornadoes associated with Tropical
    Depression Claudette will continue through this evening and
    overnight. A new Tornado Watch will be needed prior to 00z.

    DISCUSSION...Tropical Depression Claudette was located over
    west-central AL, and continuing to move northeast (see latest NHC
    Advisory for additional details). Mesoanalysis and area VWP data
    continue to show a favorable environment for low-level rotation with
    0-1 km SRH of 150-200 m2/s2 across much of the current watch area.=20 Short-range guidance suggests relatively strong 850-mb wind fields
    of 40-45 kt will remain in place overnight across the area, and dew
    points in the 70s will result in surface-based instability through
    the overnight hours. Thus, conditions will remain favorable beyond
    00z for a few tornadoes across southeast AL, the western FL
    Panhandle and southwest GA, and a new Tornado Watch will be
    coordinated prior to 00z.
