Risk Overview
FEMA's National Risk Index rates Mecosta County at low composite risk, with a National Risk Index score of 69.8 out of 100 — placing it in the 70th 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.
Most of Mecosta County's expected losses come from strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Very High risk — $11M in expected annual loss and about 2.30 events per year; winter weather (heavy snow, blizzards, and hazardous winter conditions) at High risk — $424K in expected annual loss and about 19.26 events per year; and landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $4K in expected annual loss and about 0.19 events per year. Across all hazards, FEMA estimates $24M in expected annual loss for a population of 40K.
Beyond physical exposure, Mecosta 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.
The federal record bears this out: Mecosta County has received 13 federal disaster declarations since 1975, including 4 for flood events and 3 for snowstorm events. The most recent was Severe Storms, Tornadoes, and Flooding (flood), declared in June 2026.
Among 83 Michigan counties, Mecosta County ranks #24 for overall natural disaster risk.
