Risk Overview
FEMA's National Risk Index rates McDowell County at low composite risk, with a National Risk Index score of 59.2 out of 100 — placing it in the 59th 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.
The county's risk is driven primarily by landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $143K in expected annual loss and about 1.33 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $574K in expected annual loss and about 1.58 events per year; and riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Low risk — $12M in expected annual loss and about 1.18 events per year. Across all hazards, FEMA estimates $17M in expected annual loss for a population of 45K.
Beyond physical exposure, McDowell 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: McDowell County has received 21 federal disaster declarations since 1973, including 9 for hurricane events and 3 for snowstorm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 100 North Carolina counties, McDowell County ranks #69 for overall natural disaster risk.
