The verdict
Two federal records point in the busier direction for Rockingham County. Its 35 FEMA declarations are 10% above the New Hampshire county mean and exceed the count for 93% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 14%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Rockingham County is led by Riverine Flooding (about $54.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Coastal Flooding carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Rockingham County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 2,165 claims and $30.8M 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 $14.2K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
The declaration register points in the busier direction. Rockingham County's 35 federal records stand 10% above the New Hampshire county mean of 31.9. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.
FEMA National Risk Index
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 85.8/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $89.8M 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, Coastal Flooding stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 8 times per year here.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 35 entries for Rockingham County, including 24 Major Disaster records, 10% above the New Hampshire county mean. Across the 52-year span, that works out to 0.7 declarations a year. Severe Storm leads the file with 12 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Rockingham 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 |
|---|---|---|
| Coastal Flooding | Relatively High | an average of 8 times per year |
| Ice Storm | Relatively High | an average of 2 times per year |
| Riverine Flooding | Relatively Moderate | an average of 1.2 times per year |
| Earthquake | Relatively Low | roughly once every 458 years |
| Hurricane | Relatively Moderate | roughly once every 7 years |
| Drought | Relatively Moderate | 5.6 modeled event-days per year |
| Lightning | Relatively Moderate | an average of 20 times per year |
| Tornado | Relatively Moderate | roughly once every 8 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Rockingham County's record, 34% 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: Coastal Flooding
Coastal Flooding is modeled separately from riverine flooding because its driver is different: surge, tide and wave action rather than a watershed draining. It is also the hazard whose baseline is moving, since the same storm rides on a higher starting sea level than it used to.
Worth noting for Rockingham County: the model and the federal record do NOT point at the same hazard. Coastal Flooding carries the highest modeled rating (Relatively High), while the county's declaration history is led by Severe Storm. 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.

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 Rockingham County
Rockingham County, NH has 35 federal declaration records, 10% more than the New Hampshire county mean of 32; its history sits in PlainHazard's high activity band.
- Within this above-state-average declaration file, major disaster leads with 24 of 35 records; the category describes past federal action, not the next likely hazard. New Hampshire overview
- The state benchmark and national rank point the same way: this count tops the New Hampshire mean and the totals for 93% of 3,266 U.S. counties. Most-disaster rankings
