18 FEMA disaster declarations (1967-2022), with a FEMA National Risk Index rating of Very Low. Most common hazard: Severe Storm.
The verdict
Two federal records point in the busier direction for Knox County. Its 18 FEMA declarations are 7% above the Nebraska county mean and exceed the count for 37% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 30%, based on modeled expected annual loss, social vulnerability, and community resilience.
FEMA's National Risk Index and its declaration registry are separate measures. This county's registry includes Major Disaster (DR) and Emergency (EM) records; an EM authorizes a narrower set of federal assistance than a DR.

FEMA's modeled annual dollar loss for Knox County is led by Riverine Flooding (about $3.6M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Drought carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.
Source: FEMA National Risk Index (December 2025 release) - Expected Annual Loss vs composite risk rating by hazard.
This county's FEMA National Risk Index composite lands at 29.7/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $9.6M in annualized losses), tempered or compounded by a Relatively Low social-vulnerability score and Relatively Moderate community-resilience score. Among the 18 modeled hazards, Drought carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at 32 modeled event-days per year here, based on 959 historical events on record.
This county has a small entry in FEMA's NFIP paid-claims table: 26 claims and $804.6K 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. Knox County's 18 federal records stand 7% 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.

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 |
|---|---|---|
| Drought | Relatively Moderate | 32 modeled event-days per year |
| Wildfire | Relatively Low | roughly once every 784 years |
| Hail | Relatively Moderate | an average of 5.6 times per year |
| Winter Weather | Relatively Moderate | an average of 16 times per year |
| Ice Storm | Relatively Moderate | roughly once every 1 years |
| Cold Wave | Relatively Low | an average of 6.5 times per year |
| Tornado | Relatively Low | roughly once every 1 years |
| Landslide | Very Low | roughly once every 2 years |
| Strong Wind | Relatively Low | an average of 2.8 times per year |
| Riverine Flooding | Very Low | an average of 1.1 times per year |
| Heat Wave | Very Low | 4.9 modeled event-days per year |
| Lightning | Relatively Low | an average of 39 times per year |
| Earthquake | Very Low | roughly once every 1,812 years |

Severe Storm is the most frequent declaration type on Knox County's record, 39% 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.
FEMA categorizes declarations as Major Disasters (DR), Emergencies (EM), or Fire Management Assistance (FM).

Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.
Worth noting for Knox County: the model and the federal record do NOT point at the same hazard. Drought 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.
Data-matched county comparisons
Comparisons use published FEMA declaration fields plus the National Risk Index composite for Knox County. Record similarity, not a safety rating.
Knox County shows 18 FEMA declarations, led by Severe Storm.
Knox County: 15 of 18 of its declarations are Major.
Knox County: NRI composite 29.7 (Very Low).
Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.
