Risk Overview
Wayne County carries a low composite natural disaster risk, with a National Risk Index score of 43.0 out of 100 — placing it in the 43rd 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 earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $936K in expected annual loss and about 0.00 events per year; tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $2M in expected annual loss and about 0.60 events per year; and cold wave (prolonged spells of dangerously low temperatures) at Medium risk — $1M in expected annual loss and about 1.16 events per year. Across all hazards, FEMA estimates $9M in expected annual loss for a population of 16K.
Beyond physical exposure, Wayne 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.
History supports the rating: Wayne County has received 27 federal disaster declarations since 1973, including 16 for severe storm events and 4 for flood events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.
Among 95 Tennessee counties, Wayne County ranks #63 for overall natural disaster risk.
