Risk Overview
Charlotte County carries a high composite natural disaster risk, with a National Risk Index score of 95.2 out of 100 — placing it in the 95th national percentile and in the upper tier of natural-disaster risk nationally. 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 Very High risk — $100M in expected annual loss and about 0.24 events per year; lightning (electrical discharges from storms that ignite fires and cause casualties) at Very High risk — $2M in expected annual loss and about 99.98 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Medium risk — $2M in expected annual loss and about 0.01 events per year. Across all hazards, FEMA estimates $131M in expected annual loss for a population of 187K.
Beyond physical exposure, Charlotte 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: Charlotte County has received 42 federal disaster declarations since 1968, including 19 for hurricane events and 5 for tropical storm events. The most recent was Hurricane Milton (hurricane), declared in October 2024.
Among 67 Florida counties, Charlotte County ranks #18 for overall natural disaster risk.
