Risk Overview
Overall natural disaster risk in Andrew County is very low, with a National Risk Index score of 22.1 out of 100 — placing it in the 22nd 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 landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $11K in expected annual loss and about 0.20 events per year; drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $857K in expected annual loss and about 21.22 events per year; and tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $3M in expected annual loss and about 0.29 events per year. Across all hazards, FEMA estimates $11M in expected annual loss for a population of 18K.
Beyond physical exposure, Andrew 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 county's disaster history tells the same story: Andrew County has received 31 federal disaster declarations since 1965, including 15 for severe storm events and 9 for flood events. The most recent was Severe Storms, Straight-Line Winds, Tornadoes, and Flooding (severe storm), declared in September 2021.
