Risk Overview
FEMA's National Risk Index rates Branch County at low composite risk, with a National Risk Index score of 51.8 out of 100 — placing it in the 52nd 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 Medium risk — $699K in expected annual loss and about 2.88 events per year; tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $2M in expected annual loss and about 0.26 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $842K in expected annual loss and about 5.15 events per year. Across all hazards, FEMA estimates $14M in expected annual loss for a population of 45K.
Beyond physical exposure, Branch County has a high 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). Higher vulnerability is partly offset by strong community resilience and recovery capacity.
History supports the rating: Branch County has received 6 federal disaster declarations since 1965, including 2 for biological events and 2 for snowstorm events. The most recent was Covid-19 Pandemic (biological), declared in March 2020.
Among 83 Michigan counties, Branch County ranks #42 for overall natural disaster risk.
