Risk Overview
Logan County carries a low composite natural disaster risk, with a National Risk Index score of 74.7 out of 100 — placing it in the 75th 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 ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $2M in expected annual loss and about 1.12 events per year; cold wave (prolonged spells of dangerously low temperatures) at High risk — $10M in expected annual loss and about 2.16 events per year; and tornado (violently rotating columns of air capable of catastrophic local damage) at High risk — $10M in expected annual loss and about 0.89 events per year. Across all hazards, FEMA estimates $35M in expected annual loss for a population of 49K.
Beyond physical exposure, Logan County has a low social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
History supports the rating: Logan County has received 47 federal disaster declarations since 1974, including 17 for severe storm events and 10 for severe ice storm events. The most recent was Wildfires and Straight-Line Winds (fire), declared in May 2025.
Among 77 Oklahoma counties, Logan County ranks #24 for overall natural disaster risk.
