Risk Overview
FEMA's National Risk Index rates Troup County at low composite risk, with a National Risk Index score of 59.9 out of 100 — placing it in the 60th 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 hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $880K in expected annual loss and about 0.08 events per year; tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $3M in expected annual loss and about 0.33 events per year; and lightning (electrical discharges from storms that ignite fires and cause casualties) at Medium risk — $437K in expected annual loss and about 62.66 events per year. Across all hazards, FEMA estimates $17M in expected annual loss for a population of 69K.
Beyond physical exposure, Troup 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.
History supports the rating: Troup County has received 14 federal disaster declarations since 1977, including 4 for hurricane events and 3 for severe storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 159 Georgia counties, Troup County ranks #42 for overall natural disaster risk.
