Risk Overview

About Natural Disaster Risk in Washington County, Maryland

Washington County faces above-average disaster risk

Washington County's composite risk score of 68.77 exceeds both the national average and Maryland's state average of 60.22, placing it in the 'relatively low' risk category. The county's risk is driven primarily by earthquake and hurricane exposure rather than wind or water hazards.

Higher-risk county in Maryland's west

Washington County ranks above the state average with a composite risk score of 68.77, making it one of Maryland's moderate-risk areas. Its western location exposes it to earthquake hazards and tornado activity that neighboring counties experience less intensely.

Riskier than most neighbors, similar to Worcester

Washington County (68.77) faces greater overall risk than Queen Anne's (35.62), St. Mary's (42.56), and Talbot (42.37) counties, while closely matching Worcester County (68.19). Its position in western Maryland creates a distinct hazard profile compared to Eastern Shore neighbors.

Earthquakes and tornadoes drive your exposure

Earthquake risk reaches 76.53 in Washington County—the highest among this cohort of counties—while tornado risk stands at 61.96. Together these seismic and wind threats account for most of your elevated overall risk, reflecting your western Maryland location near the Appalachian region.

Standard coverage plus earthquake protection

Washington County's above-average earthquake risk (76.53) makes earthquake insurance a valuable addition to your standard homeowners policy, unlike most Maryland counties. Ensure your tornado coverage is robust and verify your policy's seismic protection—these represent your primary hazard exposures.

Risk Advisory: Washington County

Risk Verdict

At the 69th percentile nationally, Washington County experiences a manageable level of natural hazard risk that falls below the U.S. median. Washington County's risk profile calls for targeted preparedness, focusing on the hazard categories that dominate the county's score.

Hazard Breakdown

Hurricane risk is Washington County's dominant natural hazard, ranked at the 86th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 77th percentile nationally. Additional tracked hazards include flood (73th percentile), tornado (62th percentile), wildfire (38th percentile).

Preparedness Context

Washington County's primary hazard, hurricane, ranks at the 86th percentile nationally. Having a designated out-of-area contact, a pre-packed go-bag with medications and documents, and a confirmed evacuation route reduces decision-making load when a storm intensifies rapidly. Washington County's earthquake exposure at the 77th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. The National Hurricane Center's official forecast cone and local NWS office watches and warnings are the authoritative sources for Washington County storm tracking; households benefit from bookmarking these before storm season rather than relying on social media during an event.

Regional Context

Washington County falls 8.5 points above Maryland's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Washington County higher risk than average?
Washington County's composite risk score of 69th percentile is above the Maryland state average of 60th percentile. This elevated risk is driven by hurricane exposure (86th percentile), along with earthquake and flooding and tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
