Risk Overview
FEMA's National Risk Index rates Letcher County at low composite risk, with a National Risk Index score of 66.6 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.
Risk here concentrates in landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $43K in expected annual loss and about 1.12 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $15M in expected annual loss and about 2.04 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $197K in expected annual loss and about 0.01 events per year. Across all hazards, FEMA estimates $17M in expected annual loss for a population of 21K.
Beyond physical exposure, Letcher 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: Letcher County has received 40 federal disaster declarations since 1967, including 16 for severe storm events and 14 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 120 Kentucky counties, Letcher County ranks #27 for overall natural disaster risk.
