Boone County's FEMA Risk Index score
What does Boone County's hazard record show?
FEMA National Risk Index
FEMA's data shows an elevated National Risk Index composite of 43.4/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $12.9M in annualized losses). Social vulnerability (Relatively Moderate) and community resilience (Very High) both factor into how that raw exposure plays out on the ground. Of the 18 hazards FEMA models, Hail stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 5.9 times per year here, based on 226 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 15 claims and $134.8K 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. Boone 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 Boone 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 |
|---|---|---|
| Hail | Relatively High | an average of 5.9 times per year |
| Drought | Relatively Moderate | 40 modeled event-days per year |
| Strong Wind | Relatively Moderate | an average of 2.8 times per year |
| Winter Weather | Relatively Moderate | an average of 15 times per year |
| Ice Storm | Relatively Moderate | roughly once every 2 years |
| Cold Wave | Relatively Low | an average of 5.6 times per year |
| Tornado | Relatively Low | roughly once every 2 years |
| Wildfire | Very Low | roughly once every 3,117 years |
| Riverine Flooding | Very Low | roughly once every 1 years |
| Lightning | Relatively Low | an average of 42 times per year |
| Heat Wave | Very Low | 4.4 modeled event-days per year |
| Landslide | Very Low | roughly once every 3 years |
| Earthquake | Very Low | roughly once every 1,866 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Boone County's record, 40% 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: Hail
Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.
For Boone County the two measures on this page point the same way: Hail 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.
