Risk Overview

FEMA's National Risk Index rates Lee County at medium composite risk, with a National Risk Index score of 81.3 out of 100 — placing it in the 81st 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.

Most of Lee County's expected losses come from earthquake (ground shaking from sudden movement along geologic faults) at Medium risk — $8M in expected annual loss and about 0.00 events per year; cold wave (prolonged spells of dangerously low temperatures) at High risk — $8M in expected annual loss and about 1.16 events per year; and heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at Medium risk — $2M in expected annual loss and about 16.21 events per year. Across all hazards, FEMA estimates $38M in expected annual loss for a population of 83K.

Beyond physical exposure, Lee County has a high social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). Higher vulnerability is partly offset by strong community resilience and recovery capacity.

The county's disaster history tells the same story: Lee County has received 22 federal disaster declarations since 1973, including 11 for severe storm events and 5 for hurricane events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.

Among 82 Mississippi counties, Lee County ranks #12 for overall natural disaster risk.
