Risk Overview
DeSoto County carries a medium composite natural disaster risk, with a National Risk Index score of 81.6 out of 100 — placing it in the 82nd national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
The county's risk is driven primarily by hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at High risk — $17M in expected annual loss and about 0.24 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at High risk — $1M in expected annual loss and about 98.38 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $387K in expected annual loss and about 0.01 events per year. Across all hazards, FEMA estimates $26M in expected annual loss for a population of 34K.
Beyond physical exposure, DeSoto County has a very high social vulnerability rating (how susceptible the population is to harm) and a very low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
History supports the rating: DeSoto County has received 38 federal disaster declarations since 1977, including 17 for hurricane events and 4 for tropical storm events. The most recent was Hurricane Milton (hurricane), declared in October 2024.
Among 67 Florida counties, DeSoto County ranks #38 for overall natural disaster risk.
