Risk Overview
Wayne County carries a low composite natural disaster risk, with a National Risk Index score of 79.8 out of 100 — placing it in the 80th 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.
Risk here concentrates in landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $89K in expected annual loss and about 1.49 events per year; heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at Medium risk — $2M in expected annual loss and about 4.53 events per year; and riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $26M in expected annual loss and about 2.29 events per year. Across all hazards, FEMA estimates $31M in expected annual loss for a population of 39K.
Beyond physical exposure, Wayne County has a 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.
History supports the rating: Wayne County has received 33 federal disaster declarations since 1967, including 14 for severe storm events and 9 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 55 West Virginia counties, Wayne County ranks #3 for overall natural disaster risk.
