Risk Overview

About Natural Disaster Risk in Atlantic County, New Jersey

Atlantic County's moderate risk profile

Atlantic County scores 92.97 on the composite risk scale, placing it slightly above the national average and marking it as relatively moderate in overall disaster risk. This score reflects meaningful exposure to multiple hazard types, particularly coastal and water-related threats that define much of the county's geography.

Ranking among New Jersey counties

At 92.97, Atlantic County exceeds New Jersey's state average composite risk score of 90.81, putting it in the middle-to-upper tier of risk exposure statewide. The county faces higher-than-average vulnerability compared to many inland New Jersey communities.

How Atlantic compares nearby

Atlantic County's risk profile sits between Cape May County (91.03) to the south and Burlington County (93.61) to the north, making it a moderate risk zone along New Jersey's shore. All three counties share substantial flood and hurricane exposure, though Atlantic's wildfire risk (94.31) is notably higher than Cape May's.

Atlantic's top three hazards

Hurricane risk dominates at 95.79, making Atlantic one of New Jersey's most vulnerable counties for major storms and coastal surge. Flood risk (96.20) and wildfire risk (94.31) round out the top threats, each posing significant seasonal challenges across different parts of the county.

Insurance for Atlantic County homeowners

Homeowners and renters in Atlantic County should prioritize flood insurance, which is critical given the 96.20 flood risk score and is often excluded from standard policies. Consider also reviewing coverage for hurricane damage and wind, which affect coastal and inland properties alike.

Risk Verdict

Atlantic County's overall risk score at the 93th percentile nationally signals meaningful exposure to multiple natural hazard types. Comprehensive household preparedness — including reviewing insurance, maintaining emergency supplies, and knowing evacuation routes — is strongly recommended.

Hazard Breakdown

Flood risk is Atlantic County's dominant natural hazard, ranked at the 96th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 96th percentile nationally. Additional tracked hazards include wildfire (94th percentile), earthquake (88th percentile), tornado (53th percentile).

Preparedness Context

Atlantic County sits at the 96th percentile nationally for flood exposure. Knowing your property's flood zone designation — available at FEMA's Flood Map Service Center — is the first step toward understanding actual exposure and insurance options. Secondary hurricane exposure at the 96th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. Regardless of specific hazard, Atlantic County households benefit from a practiced communication plan: a designated out-of-state contact and a pre-agreed evacuation destination established before the season's peak risk period.

Regional Context

The county's composite score diverges by only 2.2 points from the New Jersey average, making Atlantic County's hazard profile broadly typical for this part of the state.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Atlantic County higher risk than average?
Atlantic County's composite risk score of 93th percentile is above the New Jersey state average of 91th percentile. This elevated risk is driven by flooding exposure (96th percentile), along with hurricane and wildfire and earthquake and tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
