Risk Overview
Overall natural disaster risk in Walker County is low, with a National Risk Index score of 72.0 out of 100 — placing it in the 72nd 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 High risk — $9M in expected annual loss and about 0.34 events per year; cold wave (prolonged spells of dangerously low temperatures) at Medium risk — $6M in expected annual loss and about 1.58 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $2M in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $30M in expected annual loss for a population of 68K.
Beyond physical exposure, Walker County has a medium 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). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
The county's disaster history tells the same story: Walker County has received 19 federal disaster declarations since 1973, including 5 for severe storm events and 4 for hurricane events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
