The secondary flood hazard at the 25th percentile nationally adds seasonal complexity to Buffalo County's preparedness calendar, since flood and tornado risk often peak at different points in the year. The highest-risk window for tornado fatalities is overnight, when Buffalo County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Buffalo County households.
