The secondary hurricane hazard at the 76th percentile nationally adds seasonal complexity to Austin County's preparedness calendar, since hurricane and tornado risk often peak at different points in the year. Austin County county emergency management typically publishes annual severe-weather preparedness guides tailored to local tornado patterns; households benefit from reviewing these before storm season begins each spring.
