Risk Overview

Overall natural disaster risk in Buffalo County is low, with a National Risk Index score of 66.0 out of 100 — placing it in the 66th 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 hail (ice stones from severe thunderstorms that damage property and crops) at High risk — $13M in expected annual loss and about 6.95 events per year; strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at High risk — $6M in expected annual loss and about 3.69 events per year; and drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $2M in expected annual loss and about 39.82 events per year. Across all hazards, FEMA estimates $37M in expected annual loss for a population of 50K.

Beyond physical exposure, Buffalo County has a very 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.

The federal record bears this out: Buffalo County has received 18 federal disaster declarations since 1967, including 10 for severe storm events and 4 for flood events. The most recent was Severe Storms, Straight-Line Winds, and Tornadoes (severe storm), declared in February 2022.

Among 93 Nebraska counties, Buffalo County ranks #7 for overall natural disaster risk.
