Risk Overview
Clay County carries a very low composite natural disaster risk, with a National Risk Index score of 22.3 out of 100 — placing it in the 22nd 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.
Risk here concentrates in landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $49K in expected annual loss and about 0.98 events per year; avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Low risk — $2K in expected annual loss and about 0.01 events per year; and riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Low risk — $4M in expected annual loss and about 1.54 events per year. Across all hazards, FEMA estimates $5M in expected annual loss for a population of 8K.
Beyond physical exposure, Clay County has a very high social vulnerability rating (how susceptible the population is to harm) and a very 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 county's disaster history tells the same story: Clay County has received 26 federal disaster declarations since 1967, including 10 for severe storm events and 4 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 55 West Virginia counties, Clay County ranks #48 for overall natural disaster risk.
