Custer County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Custer County is led by Riverine Flooding (about $6.6M Expected Annual Loss, Historical Loss Ratio Relatively High), while Winter Weather carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Custer County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 28.0/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $11.1M in annualized losses), tempered or compounded by a Very Low social-vulnerability score and Very Low community-resilience score. Among the 18 modeled hazards, Winter Weather carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 17 times per year here, based on 315 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 11 claims and $83.4K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.
The declaration register points in the busier direction. Custer County's 20 federal records stand 19% above the Nebraska county mean of 16.8. 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.

How often does each hazard strike Custer 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 Moderate | an average of 17 times per year |
| Wildfire | Relatively Low | roughly once every 465 years |
| Drought | Relatively Moderate | 43 modeled event-days per year |
| Hail | Relatively Low | an average of 6.6 times per year |
| Ice Storm | Relatively Low | roughly once every 9 years |
| Tornado | Relatively Low | an average of 1.5 times per year |
| Landslide | Very Low | an average of 2.1 times per year |
| Riverine Flooding | Relatively Low | an average of 1.2 times per year |
| Heat Wave | Very Low | 4.6 modeled event-days per year |
| Lightning | Very Low | an average of 43 times per year |
| Strong Wind | Relatively Low | an average of 2.5 times per year |
| Earthquake | Very Low | roughly once every 1,580 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Custer County's record, 60% 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 Custer County: the model and the federal record do NOT point at the same hazard. Winter Weather carries the highest modeled rating (Relatively Moderate), 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.
