    Concerning...Severe Thunderstorm Watch 91...

    The severe weather threat for Severe Thunderstorm Watch 91

    SUMMARY...Storms continue to develop across/spread into central
    Florida/WW 91. Risk for damaging winds is expected to ramp up over
    the next couple of hours, beginning over western portions of the

    DISCUSSION...Latest surface analysis shows an outflow boundary lying west-to-east across central Florida, from roughly Tampa to Orlando
    to Melbourne. A loosely organized warm-advection band of storms is
    occurring north of this boundary, from roughly Citrus to
    Seminole/Orange Counties, where local wind/hail potential exists.

    Meanwhile, a much larger area of storms remains over the eastern
    Gulf of Mexico, with the leading edge of this convection now
    approaching coastal Citrus/Hernando/Pasco/Pinellas Counties. This
    band has remained rather loosely defined, but has recently begun to
    take ona bit more of an organized/bowing character. This more organized/advancing portion of the band will move onshore across the aforementioned counties over the next hour, and should progress
    eastward in the vicinity of the outflow boundary. The organizing
    character of the storms, and focused ascent in the vicinity of the
    boundary, suggests a corridor of enhanced severe risk evolving in
    the short term.
