Grant County faces moderate disaster risk

Grant County's composite risk score of 33.17 and Very Low rating indicate below-average natural disaster exposure compared to the nation. However, the county sits noticeably below West Virginia's state average of 49.21.

Low-risk county in eastern West Virginia

Grant County's score of 33.17 places it in the lower-risk category statewide, approximately one-third below the West Virginia average of 49.21. The county benefits from an eastern mountain location that moderates many hazard types.

Higher risk than Gilmer, lower than Hardy

Grant's score of 33.17 exceeds Gilmer County's exceptionally low 11.45 but falls below Hardy County (42.46) and Hampshire County (38.01). The county's wildfire (51.46) and flood risks (57.86) are elevated relative to its closest neighbors.

Flood, wildfire, and hurricane top concerns

Grant County faces significant flood risk (57.86) and wildfire exposure (51.46), with hurricane impact also notable at 64.58. Tornado and earthquake risks are comparatively low at 14.69 and 28.56 respectively.

Flood and wildfire insurance protections matter

Grant County residents should prioritize flood insurance given the 57.86 risk score, particularly in stream valleys and floodplains. Homeowners should also ensure adequate property coverage and maintain defensible space around structures due to wildfire risk of 51.46.

Risk Verdict

Compared to the nation's 3,144 counties, Grant County ranks at the 33th percentile for natural disaster risk — toward the safer end of the spectrum.

Hazard Breakdown

Hurricane risk is Grant County's dominant natural hazard, ranked at the 65th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 58th percentile nationally. Additional tracked hazards include wildfire (51th percentile), earthquake (29th percentile), tornado (15th percentile).

Preparedness Context

With hurricane ranked at the 65th percentile nationally, Grant County sits in a zone where multi-day supply readiness matters: grid outages after landfalling storms can last one to three weeks in heavily affected areas. Flood at the 58th percentile nationally is Grant County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. Insurance gaps are the most common post-hurricane financial shock: standard homeowners policies typically exclude flood damage and may have a separate wind deductible. Grant County households benefit from a pre-season insurance review confirming both wind and flood coverage.

Regional Context

At 16.0 points below the West Virginia state average, Grant County is among the lower-risk counties in the state for natural disaster exposure.
