Risk Overview

About Natural Disaster Risk in Brunswick County, North Carolina

Brunswick faces highest national risk

Brunswick County's composite risk score of 95.77 places it in the relatively high category—significantly above the national average. With nearly every hazard type scoring above 82, Brunswick ranks among the most naturally hazardous counties in the United States.

North Carolina's riskiest county

Brunswick leads all North Carolina counties with a composite score of 95.77, towering above the state average of 66.72. This ranking reflects the county's coastal geography and exposure to compound hazards including hurricanes, flooding, and wildfires.

Significantly riskier than nearby peers

Brunswick's 95.77 score dwarfs neighbors Bladen County (84.57) and Carteret County (93.48), making it the clear outlier in the region. No adjacent county comes close to its hazard density, driven by its coastal position and oceanfront vulnerability.

Hurricanes, floods, and wildfires compound

Brunswick residents face a 99.08 hurricane risk—virtually certain exposure—paired with 89.40 flood risk and 93.35 wildfire risk. This combination makes Brunswick one of the nation's most complex disaster scenarios, requiring multi-hazard preparedness.

Comprehensive coverage is non-negotiable

Homeowners must prioritize flood, wind, and comprehensive property insurance given Brunswick's compound risks. Consider elevation or reinforcement of your home's structural integrity, and maintain an updated evacuation plan with critical documents stored off-site.

Risk Verdict

FEMA's National Risk Index places Brunswick County at the 96th percentile nationally — in the high-risk bracket for U.S. counties. Residents should prioritize a formal household emergency plan, including evacuation routes, insurance review, and a well-stocked emergency kit.

Hazard Breakdown

Hurricane risk is Brunswick County's dominant natural hazard, ranked at the 99th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 93th percentile nationally. Additional tracked hazards include flood (89th percentile), tornado (87th percentile), earthquake (83th percentile).

Preparedness Context

Hurricane exposure at the 99th percentile nationally makes Brunswick County a county where pre-season preparedness — not storm-day preparation — determines outcomes. Brunswick County evacuation decisions under a watch or warning benefit from prior planning, not routes improvised under time pressure. Wildfire at the 93th percentile nationally is Brunswick County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. Brunswick 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

Brunswick County is 29.0 composite risk points above the North Carolina average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.
