Dramatically higher than neighbors
Allen County's score of 90.84 dwarfs nearby Adams County (52.13) and Whitley County to the east, making it a clear risk outlier in the region. Your county faces threats significantly more severe than surrounding areas.
Tornadoes and floods dominate threats
Tornado risk reaches 97.46—the highest single hazard score in your county—while flooding poses severe risk at 93.54, reflecting vulnerability to spring storms and precipitation events. Earthquake risk of 84.89 adds a third major concern.
