Risk Overview

About Natural Disaster Risk in New Hanover County, North Carolina

New Hanover's disaster risk ranks high nationally

With a composite risk score of 96.12, New Hanover County faces significantly elevated natural disaster risk compared to the nation's average. This 'Relatively High' rating reflects exposure to multiple hazard types that threaten homes, businesses, and infrastructure across the county.

Top-tier risk in North Carolina

New Hanover's score of 96.12 towers above North Carolina's state average of 66.72, placing it among the highest-risk counties in the state. Coastal location and low elevation expose the county to hazards that most inland North Carolina communities rarely face.

Riskier than nearby Pender and Onslow

New Hanover (96.12) carries slightly more total risk than neighboring Onslow County (94.97) and Pender County (86.93), though all three coastal counties share similar hurricane and flood vulnerabilities. These three form a high-risk coastal corridor where storm surge and flooding pose persistent threats.

Hurricanes and tornadoes pose greatest threats

New Hanover's hurricane risk score of 99.12 is among the highest possible, with tropical storms regularly bringing dangerous winds and storm surge to the coast. Tornado risk of 90.36 and flood risk of 89.89 add additional layers of hazard that can strike with little warning.

Comprehensive coverage is essential

Standard homeowners insurance typically excludes flood and wind damage; New Hanover residents should secure standalone flood insurance and verify hurricane deductibles (often 5–10% of home value) with their insurer. Consider reinforcing doors, windows, and roof attachments to withstand high winds while keeping emergency supplies accessible.

Risk Verdict

At the 96th percentile nationally, New Hanover County is among the more hazard-exposed counties in the United States. Proactive preparedness — not reactive response — is key to managing life in one of the country's higher-risk counties; New Hanover County residents should plan accordingly.

Hazard Breakdown

Hurricane risk is New Hanover County's dominant natural hazard, ranked at the 99th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 90th percentile nationally. Additional tracked hazards include flood (90th percentile), wildfire (83th percentile), earthquake (81th percentile).

Preparedness Context

At the 99th percentile nationally for hurricane exposure, New Hanover 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. New Hanover County's tornado exposure at the 90th 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. New Hanover County households near tidal water or low-elevation areas should verify whether they are in a storm surge risk zone.

Regional Context

At 29.4 points above the North Carolina state average, New Hanover County carries meaningfully higher natural disaster exposure than a typical North Carolina county.
