The verdict
Warren County has a nationally busy FEMA history: 27 declarations, more than 78% of counties in this registry. But the state comparison tempers that reading: the total is 9% below the New Jersey county mean. FEMA's separate National Risk Index places the county in the riskiest 19%; that score models loss and vulnerability rather than counting declarations.

FEMA National Risk Index composite score vs. the New Jersey county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Warren County is led by Riverine Flooding (about $37.5M Expected Annual Loss, Historical Loss Ratio Relatively High), while Strong Wind carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Warren County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 1,272 claims and $32.6M 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 $25.6K. 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 Warren County has 27. The gap is 9% 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 80.8/100 (Relatively Low). Expected Annual Loss is rated Relatively Moderate (roughly $57.3M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Strong Wind stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 6.2 times per year here, based on 236 historical events on record.
Declaration frequency
Nationally, Warren County's 27 FEMA records form a high-volume history; within New Jersey, however, the count is 9% below the county mean. 16 entries carry the Major Disaster classification. The largest incident group is Severe Storm, appearing 8 times. The full 58-year record averages 0.5 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Warren 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 |
|---|---|---|
| Strong Wind | Relatively High | an average of 6.2 times per year |
| Cold Wave | Relatively Moderate | an average of 1 time per year |
| Riverine Flooding | Relatively Moderate | an average of 2.3 times per year |
| Winter Weather | Relatively Moderate | an average of 15 times per year |
| Hurricane | Relatively Low | roughly once every 19 years |
| Drought | Relatively Moderate | 2.2 modeled event-days per year |
| Landslide | Relatively Low | roughly once every 3 years |
| Lightning | Relatively Moderate | an average of 33 times per year |
| Heat Wave | Relatively Low | 5.4 modeled event-days per year |
| Earthquake | Relatively Low | roughly once every 751 years |
| Ice Storm | Relatively Moderate | an average of 1.7 times per year |
| Tornado | Relatively Low | roughly once every 7 years |
| Avalanche | Very Low | roughly once every 100 years |
| Wildfire | Very Low | roughly once every 8,070 years |
| Hail | Very Low | an average of 2.6 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Warren County's record, 30% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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: Strong Wind
Strong Wind covers damaging non-thunderstorm, non-tornadic wind, the kind produced by steep pressure gradients and downslope events. It is a broad, frequent, low-drama hazard: roofs, signage, power lines and high-profile vehicles, spread across a wide area rather than concentrated on a path.
For Warren County the two measures on this page point the same way: Strong Wind is the county's highest-rated modeled hazard (Relatively High), and Severe Storm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Data Sources & Methodology
Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.
Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.
Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.
This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.
What this means for Warren County
Against a New Jersey county mean of 30 declarations, Warren County, NJ records 27, or 9% fewer. PlainHazard classifies that historical total as high activity.
- Major Disaster is the largest group (16 of 27) in a declaration history that remains below its state benchmark; frequency here is not a forecast. New Jersey overview
- Nationally the county exceeds 78% of recorded county totals, but its own New Jersey benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
- The large NFIP claims file and FEMA declaration history measure different federal records; the guide explains where they overlap and where they do not. Disaster-data guide
A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
