Risk Overview

Lincoln County carries a low composite natural disaster risk, with a National Risk Index score of 58.9 out of 100 — placing it in the 59th 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.

Risk here concentrates in tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $4M in expected annual loss and about 0.55 events per year; earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $1M in expected annual loss and about 0.00 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $1M in expected annual loss and about 6.76 events per year. Across all hazards, FEMA estimates $16M in expected annual loss for a population of 35K.

Beyond physical exposure, Lincoln County has a high social vulnerability rating (how susceptible the population is to harm) and a 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: Lincoln County has received 17 federal disaster declarations since 1973, including 7 for severe storm events and 3 for flood events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.

Among 95 Tennessee counties, Lincoln County ranks #44 for overall natural disaster risk.
