Risk Overview

About Natural Disaster Risk in Somerset County, Maryland

Somerset's risk mirrors Maryland's statewide average

Somerset County's composite risk score of 59.57 sits just below Maryland's state average of 60.22, placing it in the 'relatively low' risk category. The county's risk profile is notably shaped by extreme water hazards rather than wind or seismic threats.

Mid-range risk among Maryland counties

Somerset County ranks in the middle tier of Maryland's risk landscape, with its 59.57 score placing it safely below Prince George's County (93.16) but above several other Eastern Shore counties. Its risk is concentrated in specific hazard types rather than distributed across multiple threats.

Riskier than Talbot and St. Mary's, similar to Wicomico

Somerset County (59.57) faces greater overall risk than nearby Talbot County (42.37) and St. Mary's County (42.56), but closely mirrors Wicomico County (60.78) and Worcester County (68.19). The Somerset Peninsula's unique geography creates a distinct risk profile among Eastern Shore counties.

Floods and hurricanes drive your hazard exposure

Somerset County's flood risk reaches 93.20 and hurricane risk stands at 88.78—both extreme levels that reflect the county's low-lying coastal and peninsula geography. These water-related threats vastly outweigh tornado risk (16.86) and wildfire exposure, making water hazards your dominant concern.

Flood and hurricane insurance are essential

Somerset County's extreme flood (93.20) and hurricane (88.78) risks make separate flood insurance and comprehensive wind coverage non-negotiable protections. Evaluate your home's elevation and proximity to water, and consider mitigation investments like improved drainage or storm shutters to reduce vulnerability.

Risk Advisory: Somerset County

Risk Verdict

With a national percentile rank of 60th, Somerset 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 Somerset County's dominant natural hazard, ranked at the 93th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 89th percentile nationally. Additional tracked hazards include wildfire (86th percentile), earthquake (38th percentile), tornado (17th percentile).

Preparedness Context

With flood risk ranking at the 93th percentile nationally, Somerset 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, hurricane exposure at the 89th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Registering for Somerset 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

Somerset County tracks the Maryland county average closely, sitting 0.6 composite points below the state mean — neither a standout high-risk nor low-risk county within Maryland.
