Risk Overview
Blaine County carries a very low composite natural disaster risk, with a National Risk Index score of 32.3 out of 100 — placing it in the 32nd 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.
The county's risk is driven primarily by ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $1M in expected annual loss and about 1.08 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Medium risk — $2M in expected annual loss and about 9.84 events per year; and drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $987K in expected annual loss and about 66.86 events per year. Across all hazards, FEMA estimates $10M in expected annual loss for a population of 9K.
Beyond physical exposure, Blaine County has a medium 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). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
History supports the rating: Blaine County has received 33 federal disaster declarations since 1975, including 16 for severe storm events and 10 for severe ice storm events. The most recent was Severe Storms, Straight-Line Winds, Tornadoes, and Flooding (severe storm), declared in June 2024.
Among 77 Oklahoma counties, Blaine County ranks #62 for overall natural disaster risk.
