The secondary wildfire hazard at the 90th percentile nationally adds seasonal complexity to McLennan County's preparedness calendar, since wildfire and tornado risk often peak at different points in the year. McLennan 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.
