Risk Overview

Overall natural disaster risk in Summers County is very low, with a National Risk Index score of 40.2 out of 100 — placing it in the 40th 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.

The county's risk is driven primarily by landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $29K in expected annual loss and about 0.98 events per year; cold wave (prolonged spells of dangerously low temperatures) at Medium risk — $2M in expected annual loss and about 4.37 events per year; and avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Low risk — $3K in expected annual loss and about 0.01 events per year. Across all hazards, FEMA estimates $8M in expected annual loss for a population of 12K.

Beyond physical exposure, Summers 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 federal record bears this out: Summers County has received 24 federal disaster declarations since 1967, including 9 for severe storm events and 6 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.

Among 55 West Virginia counties, Summers County ranks #35 for overall natural disaster risk.
