Risk Overview
Overall natural disaster risk in Berrien County is medium, with a National Risk Index score of 81.7 out of 100 — placing it in the 82nd national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at High risk — $3M in expected annual loss and about 4.21 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Medium risk — $2M in expected annual loss and about 2.34 events per year; and cold wave (prolonged spells of dangerously low temperatures) at Medium risk — $6M in expected annual loss and about 2.26 events per year. Across all hazards, FEMA estimates $45M in expected annual loss for a population of 154K.
Beyond physical exposure, Berrien County has a medium social vulnerability rating (how susceptible the population is to harm) and a very 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: Berrien County has received 12 federal disaster declarations since 1972, including 5 for flood events and 3 for snowstorm events. The most recent was Covid-19 Pandemic (biological), declared in March 2020.
Among 83 Michigan counties, Berrien County ranks #12 for overall natural disaster risk.
