Risk Overview
Overall natural disaster risk in Columbia County is very low, with a National Risk Index score of 42.1 out of 100 — placing it in the 42nd 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.
Risk here concentrates in ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Very High risk — $2M in expected annual loss and about 1.22 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Medium risk — $705K in expected annual loss and about 4.76 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $843K in expected annual loss and about 4.92 events per year. Across all hazards, FEMA estimates $9M in expected annual loss for a population of 23K.
Beyond physical exposure, Columbia County has a very high social vulnerability rating (how susceptible the population is to harm) and a medium 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: Columbia County has received 22 federal disaster declarations since 1973, including 8 for severe storm events and 5 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 75 Arkansas counties, Columbia County ranks #55 for overall natural disaster risk.
