The verdict
Two federal records point in the busier direction for Carroll 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 29%, based on modeled expected annual loss, social vulnerability, and community resilience.

FEMA National Risk Index composite score vs. the New Hampshire county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Carroll County is led by Riverine Flooding (about $22.6M Expected Annual Loss, Historical Loss Ratio Relatively High), while Winter Weather carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Carroll County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 290 paid claims, totaling $2.8M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $9.7K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
The declaration register points in the busier direction. Carroll 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 carries a high composite score on FEMA's National Risk Index, 71.0/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $31.0M in annualized losses), and a Relatively Low social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Winter Weather stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 22 times per year here, based on 421 historical events on record.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 35 entries for Carroll County, including 24 Major Disaster records, 10% above the New Hampshire county mean. Across the 51-year span, that works out to 0.7 declarations a year. Severe Storm leads the file with 13 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Carroll 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 | Relatively High | an average of 22 times per year |
| Ice Storm | Relatively High | an average of 1.3 times per year |
| Hurricane | Relatively Moderate | roughly once every 12 years |
| Riverine Flooding | Relatively Moderate | an average of 2.6 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Carroll County's record, 37% 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: 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 Carroll County: the model and the federal record do NOT point at the same hazard. Winter Weather 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 Carroll County
Carroll 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.
