Risk Overview

About Natural Disaster Risk in Gloucester County, Virginia

Gloucester County faces low disaster risk

Gloucester County's composite risk score of 22.61 places it in the "Very Low" category but notably higher than inland Virginia counties. This reflects its coastal location in the Mid-Atlantic, which elevates hurricane and flood exposure.

Below Virginia's average risk profile

At 22.61, Gloucester County scores well below Virginia's state average of 33.27, ranking among the lower-risk counties statewide. However, coastal geography distinguishes it from purely inland counties.

Higher risk than inland neighbors

Gloucester County's score of 22.61 exceeds inland neighbors like Goochland County (15.52) but mirrors the elevated coastal exposure seen across Virginia's Peninsula region. Proximity to the Atlantic creates unique hazard patterns.

Hurricanes and floods dominate coastal threats

Hurricane risk (75.76) and flood risk (66.60) tower over all other hazards in Gloucester County, reflecting its waterfront location on the York River and Chesapeake Bay approaches. Tornado risk (29.87) and wildfire risk (45.20) remain secondary concerns.

Hurricane and flood insurance essential

Gloucester County residents should prioritize flood insurance, especially those within mapped floodplains or near tidal areas vulnerable to storm surge. Homeowners should also reinforce roofs and windows against hurricane-force winds.

Risk Advisory: Gloucester County

Risk Verdict

Gloucester County sits in the lower tier of U.S. counties for natural disaster exposure, ranked at the 23th percentile nationally. Even at the 23th percentile, Gloucester County's composite score reflects real hazard exposure categories — knowing which ones apply locally enables targeted, efficient household preparedness.

Hazard Breakdown

Hurricane risk is Gloucester County's dominant natural hazard, ranked at the 76th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 67th percentile nationally. Additional tracked hazards include wildfire (45th percentile), earthquake (43th percentile), tornado (30th percentile).

Preparedness Context

At the 76th percentile nationally for hurricane exposure, Gloucester County households benefit from reviewing both homeowners and flood insurance coverage before storm season begins — standard policies often exclude storm surge, which is the leading cause of hurricane fatalities. Gloucester County's flood exposure at the 67th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Hurricane-force winds cause direct property damage, but storm surge causes the majority of hurricane-related deaths. Gloucester County households near tidal water or low-elevation areas should verify whether they are in a storm surge risk zone.

Regional Context

Gloucester County falls 10.7 points below Virginia's typical county risk level, making it one of the safer natural-hazard environments in the state.
