The verdict
Gloucester County has a nationally busy FEMA history: 28 declarations, more than 81% of counties in this registry. But the state comparison tempers that reading: the total is 6% below the New Jersey county mean. FEMA's separate National Risk Index places the county in the riskiest 13%; that score models loss and vulnerability rather than counting declarations.

Gloucester County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Gloucester County is led by Riverine Flooding (about $40.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Winter Weather carries the highest National Risk Index rating (Very High). EAL and risk score use different inputs; they need not agree.

What does Gloucester County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 709 claims and $4.8M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $6.8K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
Start with the state benchmark: a New Jersey county averages 29.7 federal declaration records, while Gloucester County has 28. The gap is 6% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.
FEMA National Risk Index
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 86.6/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $77.0M in annualized losses). Social vulnerability reads Very Low and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Winter Weather stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 11 times per year here, based on 203 historical events on record.

How often does each hazard strike Gloucester County?
FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.
| Hazard | NRI Risk Rating | Recurrence |
|---|---|---|
| Winter Weather | Very High | an average of 11 times per year |
| Strong Wind | Relatively High | an average of 5.8 times per year |
| Heat Wave | Relatively Moderate | 11 modeled event-days per year |
| Earthquake | Relatively Low | roughly once every 618 years |
| Ice Storm | Relatively High | roughly once every 1 years |
| Riverine Flooding | Relatively Moderate | an average of 2.6 times per year |
| Coastal Flooding | Relatively High | an average of 3.7 times per year |
| Hurricane | Relatively Moderate | roughly once every 9 years |
| Lightning | Relatively High | an average of 35 times per year |
| Wildfire | Relatively Low | roughly once every 1,064 years |
| Cold Wave | Relatively Moderate | roughly once every 1 years |
| Drought | Relatively Moderate | 7.1 modeled event-days per year |
| Tornado | Relatively Moderate | roughly once every 7 years |
| Landslide | Very Low | roughly once every 13 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Gloucester County's federal record, 32% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.
One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.
Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Winter Weather
Winter Weather in the model means the accumulation of snow and cold that disrupts rather than destroys: road closures, roof loads, burst pipes and lost heating. Its costs land heavily on transport and on households least able to absorb an interruption.
Worth noting for Gloucester County: the model and the federal record do NOT point at the same hazard. Winter Weather carries the highest modeled rating (Very High), while the county's declaration history is led by Hurricane. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
