Tornadic Activity
Since 1988, NAS has observed a definite pattern to the
severe thunderstorms that produce tornadoes. The general scenario
begins with an area or line of thunderstorms that is oriented northeast
to southwest. This line of thunderstorms moves eastward with cell movement
south to north. Large cells moving inland from the Gulf will produce tornadic
activity. It is believed that the increase in friction overland enables
the thunderstorm to produce the turning vortex that is necessary to produce
tornadoes. In the northern section of Perdido Bay, this same scenario will
produce waterspouts that will move inland. Saufley Field is located along
the northeast shoreline of Perdido Bay, and should be watched closely during
this type of thunderstorm activity.
