About Natural Disaster Risk in Clermont County, Ohio
Clermont County faces elevated disaster risk
Clermont County's composite risk score of 77.86 exceeds the national average, placing it in the "Relatively Low" category but still signaling meaningful hazard exposure. This score reflects particular vulnerability to severe weather and seismic events.
Higher risk than most Ohio counties
Clermont County scores 77.86 against Ohio's average of 55.03, ranking it among the state's higher-risk counties. This elevated standing primarily reflects tornado and flood exposure that surpasses statewide norms.
Comparable risk to Butler County
Clermont County's score of 77.86 closely matches Butler County's 91.48 in terms of risk category, though Butler faces notably higher tornado and flood threats. Both counties substantially exceed the risk levels in Clinton County (34.00).
Tornadoes and floods lead the list
Tornado risk reaches 83.62 and flood risk stands at 81.30 in Clermont County, both significantly above state averages. Earthquake risk (78.40) and wildfire risk (41.38) represent secondary concerns worth monitoring.
Invest in comprehensive storm coverage

Preparedness Context
Tornado risk is Clermont County's top-ranked natural hazard at the 84th percentile nationally. For Clermont County households, the most protective action available is identifying a reinforced interior room on the lowest floor — a bathroom, closet, or central hallway away from windows. Alongside tornado exposure, flood at the 81th percentile nationally means Clermont County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. A battery-powered NOAA All Hazards weather radio with an auto-alert tone is the highest-leverage single item for tornado preparedness in Clermont County, since it delivers warnings even when power is out and phone networks are congested.
Regional Context
Clermont County's composite risk score sits 22.8 points above the Ohio county average, placing it among the more hazard-exposed counties in the state.
