Risk Overview
Coweta County carries a low composite natural disaster risk, with a National Risk Index score of 65.6 out of 100 — placing it in the 66th 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.
Most of Coweta County's expected losses come from tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $5M in expected annual loss and about 0.31 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Medium risk — $958K in expected annual loss and about 5.12 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $363K in expected annual loss and about 0.88 events per year. Across all hazards, FEMA estimates $32M in expected annual loss for a population of 146K.
Beyond physical exposure, Coweta County has a very low 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). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
The federal record bears this out: Coweta County has received 15 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, Coweta County ranks #36 for overall natural disaster risk.
