Risk Overview
Overall natural disaster risk in Webster County is very low, with a National Risk Index score of 35.3 out of 100 — placing it in the 35th 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 — $30K in expected annual loss and about 1.49 events per year; avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Low risk — $4K in expected annual loss and about 0.01 events per year; and cold wave (prolonged spells of dangerously low temperatures) at Low risk — $848K in expected annual loss and about 3.13 events per year. Across all hazards, FEMA estimates $6M in expected annual loss for a population of 8K.
Beyond physical exposure, Webster 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.
History supports the rating: Webster County has received 23 federal disaster declarations since 1980, 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, Webster County ranks #39 for overall natural disaster risk.
