Risk Overview
FEMA's National Risk Index rates Sarasota County at high composite risk, with a National Risk Index score of 98.2 out of 100 — placing it in the 98th 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.
Most of Sarasota County's expected losses come from lightning (electrical discharges from storms that ignite fires and cause casualties) at Very High risk — $5M in expected annual loss and about 96.18 events per year; hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Very High risk — $180M in expected annual loss and about 0.23 events per year; and riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at High risk — $67M in expected annual loss and about 1.18 events per year. Across all hazards, FEMA estimates $273M in expected annual loss for a population of 434K.
Beyond physical exposure, Sarasota 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: Sarasota County has received 48 federal disaster declarations since 1968, including 21 for hurricane events and 7 for severe storm events. The most recent was Hurricane Milton (hurricane), declared in October 2024.
Among 67 Florida counties, Sarasota County ranks #10 for overall natural disaster risk.
