Risk Overview

About Natural Disaster Risk in Washington County, Rhode Island

Washington: Moderate Risk, Coastal Focus

Washington County's composite risk score of 64.03 ranks as Relatively Low nationally but reflects concentrated coastal and waterway vulnerabilities. Hurricane (82.23), flood (76.20), and earthquake (67.27) risks all exceed typical U.S. levels.

Mid-Range Risk Across Rhode Island

Washington County scores 64.03, placing it fourth among Rhode Island's five counties—7.44 points above the state average of 56.59. Only Providence County (93.67) and Kent County (69.43) exceed Washington's overall risk exposure.

Safer Than Kent and Providence, Riskier Than Coastal Counties

Washington (64.03) ranks higher than Bristol (19.40) and Newport (36.42) but below Kent (69.43) and Providence (93.67). Its south-county geography and mixed coastal-inland composition place it in the state's moderate-risk band.

Hurricane and Flood Are Washington's Main Hazards

Hurricane risk (82.23) and flood risk (76.20) dominate Washington's profile, reflecting coastal Atlantic exposure in southern towns. Tornado (29.39) and earthquake (67.27) present secondary concerns, while wildfire risk (23.06) remains manageable.

Secure Flood and Wind Coverage Now

Washington's 82.23 hurricane rating and 76.20 flood rating require separate flood insurance and comprehensive wind damage coverage—don't rely on standard homeowner policies alone. Coastal properties should also confirm earthquake riders given the county's 67.27 earthquake risk.
