Risk Overview

About Natural Disaster Risk in Holmes County, Ohio

Holmes County faces elevated disaster risk

At 60.40, Holmes County's composite risk score exceeds Ohio's 55.03 state average and sits above the national median. This relatively low rating signals above-average but manageable hazard exposure for residents and property owners.

Among Ohio's higher-risk counties

Holmes County's 60.40 score ranks it above the state average and in Ohio's upper-risk tier. The county faces more natural hazard exposure than the majority of Ohio's counties.

Riskiest county in its peer group

Holmes County's 60.40 score significantly exceeds all nearby counties: Hardin (24.43), Harrison (11.42), Henry (33.81), Highland (43.19), Jackson (35.75), and Hocking (47.30), and only trails Huron (50.29) among its eight-county cohort. It stands out as notably more hazard-exposed than its region.

Tornadoes and flooding lead, wildfire significant

Holmes County faces three substantial hazards: tornado risk (66.73), flood risk (71.18)—the highest in its peer group—and wildfire risk (46.88), all above or near state average. Hurricane (52.02) and earthquake (41.86) risks are secondary but noteworthy.

Build comprehensive, multi-hazard preparedness

Holmes County residents should bundle homeowners insurance with flood and earthquake coverage, then identify a tornado safe room and maintain a weather radio. Clear vegetation around your property, ensure proper drainage, and keep emergency supplies including water, medications, and documents in a waterproof, portable container.

Risk Advisory: Holmes County

Risk Verdict

With a national percentile rank of 60th, Holmes County faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Flood risk is Holmes County's dominant natural hazard, ranked at the 71th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 67th percentile nationally. Additional tracked hazards include hurricane (52th percentile), wildfire (47th percentile), earthquake (42th percentile).

Preparedness Context

With flood risk ranking at the 71th percentile nationally, Holmes County residents face one of the most financially damaging hazards without specialized coverage. Flood insurance through the NFIP or a private carrier is worth evaluating regardless of current mortgage requirements. Alongside flooding, tornado exposure at the 67th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Registering for Holmes County's county emergency alert system — typically through the county emergency management office's website — ensures households receive early warning when flood events develop faster than forecast.

Regional Context

At 5.4 points above the Ohio state average, Holmes County carries meaningfully higher natural disaster exposure than a typical Ohio county.
