Risk Overview
Overall natural disaster risk in McDowell County is low, with a National Risk Index score of 76.7 out of 100 — placing it in the 77th 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 — $78K in expected annual loss and about 1.78 events per year; cold wave (prolonged spells of dangerously low temperatures) at High risk — $5M in expected annual loss and about 0.84 events per year; and riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $14M in expected annual loss and about 1.79 events per year. Across all hazards, FEMA estimates $21M in expected annual loss for a population of 19K.
Beyond physical exposure, McDowell 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: McDowell County has received 27 federal disaster declarations since 1972, including 12 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, McDowell County ranks #6 for overall natural disaster risk.
