Risk Overview
Overall natural disaster risk in Nash County is low, with a National Risk Index score of 80.6 out of 100 — placing it in the 81st 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 winter weather (heavy snow, blizzards, and hazardous winter conditions) at Very High risk — $830K in expected annual loss and about 5.95 events per year; hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Medium risk — $6M in expected annual loss and about 0.21 events per year; and drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $1M in expected annual loss and about 11.45 events per year. Across all hazards, FEMA estimates $37M in expected annual loss for a population of 95K.
Beyond physical exposure, Nash 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.
The federal record bears this out: Nash County has received 28 federal disaster declarations since 1968, including 14 for hurricane events and 3 for tropical storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 100 North Carolina counties, Nash County ranks #34 for overall natural disaster risk.
