Risk Overview

About Natural Disaster Risk in Greene County, New York

Greene County faces above-average U.S. risk

Greene County's composite risk score of 68.29 places it just below New York's state average and above typical American counties, particularly due to significant flood and hurricane exposure. The county's risk profile clusters heavily in weather-related hazards rather than seismic or wildfire events.

Slightly below New York average, still mid-risk

At 68.29, Greene County scores nearly equal to New York's 69.42 average, making it one of the state's middle-tier risk communities. It ranks considerably riskier than upstate counties like Hamilton and Franklin, but safer than Kings County's extreme exposure.

One of the riskier Hudson Valley counties

Greene County (68.29) ranks among the higher-risk communities in its region, exceeding upstate peers like Herkimer (60.02) and Jefferson (63.96). Its proximity to the Hudson River and Atlantic storm systems drives elevated flood and hurricane risks compared to inland upstate neighbors.

Hurricanes and flooding are severe threats

Hurricane risk dominates at 81.44, with flood risk nearly matching at 81.77—making Greene County acutely vulnerable to coastal storm impacts driven up the Hudson Valley. Tornado risk of 54.52 ranks substantially higher than upstate neighbors, reflecting the county's exposure to Atlantic weather systems.

Hurricane and flood insurance are critical

Greene County residents must obtain flood insurance immediately, given the 81.77 risk score and river flood history. Additionally, ensure your homeowner's policy includes hurricane coverage or add a separate windstorm rider, since the 81.44 hurricane risk score demands robust protection against severe storm damage.

Risk Advisory: Greene County

Risk Verdict

Natural hazard pressure in Greene County is below the national midpoint, with a composite score at the 68th percentile. Proactive emergency planning and awareness of the specific hazards driving Greene County's score can meaningfully reduce household risk.

Hazard Breakdown

Flood risk is Greene County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 81th percentile nationally. Additional tracked hazards include earthquake (55th percentile), tornado (55th percentile), wildfire (19th percentile).

Preparedness Context

Flood risk is Greene County's top hazard at the 82th percentile nationally. Households in or near designated flood zones face elevated financial exposure; flood insurance typically requires a 30-day waiting period before it takes effect, so applying before the season is advisable. Alongside flooding, hurricane exposure at the 81th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Households across Greene County should identify the nearest community shelter and keep a basic emergency kit — water, non-perishable food, medications, flashlight, and battery radio — in a location easy to grab quickly.

Regional Context

Greene County's risk score is broadly comparable to the New York county average, with a 1.1-point gap that places the county near the center of the state's hazard distribution.
