Risk Overview
Tuscaloosa County carries a medium composite natural disaster risk, with a National Risk Index score of 90.8 out of 100 — placing it in the 91st 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.
The county's risk is driven primarily by tornado (violently rotating columns of air capable of catastrophic local damage) at High risk — $18M in expected annual loss and about 1.37 events per year; heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at Medium risk — $6M in expected annual loss and about 10.00 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at High risk — $3M in expected annual loss and about 1.79 events per year. Across all hazards, FEMA estimates $83M in expected annual loss for a population of 227K.
Beyond physical exposure, Tuscaloosa County has a medium 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). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The federal record bears this out: Tuscaloosa County has received 28 federal disaster declarations since 1973, including 11 for severe storm events and 9 for hurricane events. The most recent was Hurricane Helene (hurricane), declared in September 2024.
Among 67 Alabama counties, Tuscaloosa County ranks #6 for overall natural disaster risk.
