Risk Overview
FEMA's National Risk Index rates Wyoming County at low composite risk, with a National Risk Index score of 67.4 out of 100 — placing it in the 67th 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 Wyoming County's expected losses come from landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $78K in expected annual loss and about 1.58 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $16M in expected annual loss and about 1.14 events per year; and avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Medium risk — $145K in expected annual loss and about 0.10 events per year. Across all hazards, FEMA estimates $19M in expected annual loss for a population of 21K.
Beyond physical exposure, Wyoming County has a 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: Wyoming County has received 30 federal disaster declarations since 1967, including 12 for severe storm events and 7 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 55 West Virginia counties, Wyoming County ranks #16 for overall natural disaster risk.
