Risk Overview
Overall natural disaster risk in Warren County is very low, with a National Risk Index score of 5.3 out of 100 — placing it in the 5th national percentile and among the lowest-risk counties in the country. 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 — $148K in expected annual loss and about 0.06 events per year; drought (extended dry periods that stress water supplies and agriculture) at Low risk — $73K in expected annual loss and about 62.68 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Very Low risk — $137K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $2M in expected annual loss for a population of 5K.
Beyond physical exposure, Warren County has a very 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.
The federal record bears this out: Warren County has received 13 federal disaster declarations since 1977, including 5 for hurricane events and 2 for biological events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 159 Georgia counties, Warren County ranks #149 for overall natural disaster risk.
