Risk Overview
FEMA's National Risk Index rates Calhoun County at low composite risk, with a National Risk Index score of 44.9 out of 100 — placing it in the 45th national percentile and below the national average 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 Medium risk — $5M in expected annual loss and about 0.25 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at Medium risk — $286K in expected annual loss and about 84.50 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Very Low risk — $61K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $11M in expected annual loss for a population of 14K.
Beyond physical exposure, Calhoun County has a 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.
The federal record bears this out: Calhoun County has received 43 federal disaster declarations since 1985, including 22 for hurricane events and 8 for severe storm events. The most recent was Hurricane Helene (hurricane), declared in September 2024.
Among 67 Florida counties, Calhoun County ranks #58 for overall natural disaster risk.
