Risk Overview
FEMA's National Risk Index rates Wyandot County at very low composite risk, with a National Risk Index score of 17.4 out of 100 — placing it in the 17th 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.
The county's risk is driven primarily by ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $324K in expected annual loss and about 0.51 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $479K in expected annual loss and about 3.44 events per year; and lightning (electrical discharges from storms that ignite fires and cause casualties) at Low risk — $272K in expected annual loss and about 41.37 events per year. Across all hazards, FEMA estimates $8M in expected annual loss for a population of 22K.
Beyond physical exposure, Wyandot County has a very low 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.
The federal record bears this out: Wyandot County has received 12 federal disaster declarations since 1978, including 6 for severe storm events and 3 for snowstorm events. The most recent was Covid-19 Pandemic (biological), declared in March 2020.
Among 88 Ohio counties, Wyandot County ranks #85 for overall natural disaster risk.
