Risk Overview
FEMA's National Risk Index rates Tipton County at medium composite risk, with a National Risk Index score of 81.0 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 Tipton County's expected losses come from earthquake (ground shaking from sudden movement along geologic faults) at Medium risk — $13M in expected annual loss and about 0.01 events per year; tornado (violently rotating columns of air capable of catastrophic local damage) at High risk — $7M in expected annual loss and about 0.34 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $791K in expected annual loss and about 1.08 events per year. Across all hazards, FEMA estimates $34M in expected annual loss for a population of 61K.
Beyond physical exposure, Tipton County has a high social vulnerability rating (how susceptible the population is to harm) and a medium 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: Tipton County has received 25 federal disaster declarations since 1973, including 15 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, Tipton County ranks #14 for overall natural disaster risk.
