Risk Overview

About Natural Disaster Risk in Windham County, Vermont

Windham County faces elevated disaster risk

Windham County's composite risk score of 56.93 and "Relatively Low" rating exceed the national average substantially, reflecting significant exposure across multiple hazard types. The county's southern Vermont location subjects it to heightened hurricane and tornado risks.

Second-riskiest county in Vermont

Windham County's 56.93 score ranks it 56% above Vermont's state average of 36.44, making it the second-most hazardous county statewide. Only Windsor County (61.58) carries higher composite disaster risk in the state.

Riskier than most Vermont peers

Windham County's risk substantially exceeds Orange (26.43), Orleans (36.83), Rutland (50.48), and Washington (52.23) counties. Only Windsor County's 61.58 score surpasses Windham's exposure, making southern Vermont the state's highest-risk region.

Hurricanes, floods, and tornadoes dominate

Hurricane risk (74.55) and flood risk (71.28) represent Windham County's twin most serious threats, with tornado risk (40.01) emerging as a significant third concern. The county's southern exposure makes it particularly vulnerable to tropical storm systems and spring severe weather patterns.

Comprehensive multi-hazard insurance essential

Windham County residents need robust flood insurance, comprehensive hurricane coverage, and tornado-aware structural reinforcements to address the county's elevated risk portfolio. A professional home risk assessment, roof reinforcement, and safe room construction should be priority investments for disaster resilience.

Natural hazard pressure in Windham County is below the national midpoint, with a composite score at the 57th percentile. Proactive emergency planning and awareness of the specific hazards driving Windham County's score can meaningfully reduce household risk.

Hazard Breakdown

Hurricane risk is Windham County's dominant natural hazard, ranked at the 75th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 71th percentile nationally. Additional tracked hazards include earthquake (50th percentile), tornado (40th percentile), wildfire (21th percentile).

Preparedness Context

Hurricane exposure at the 75th percentile nationally makes Windham County a county where pre-season preparedness — not storm-day preparation — determines outcomes. Windham County evacuation decisions under a watch or warning benefit from prior planning, not routes improvised under time pressure. Flood, the county's second-ranked hazard at the 71th percentile nationally, represents an additional preparedness consideration for Windham County independent of hurricane season. Windham County residents benefit from registering with the county's special-needs evacuation registry if household members have mobility limitations, require electricity-dependent medical equipment, or cannot self-evacuate — registration in advance of storm season is required.

Regional Context

Windham County is 20.5 composite risk points above the Vermont average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.
