FEMA National Risk Index composite score vs. the Kansas county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Leavenworth County is led by Riverine Flooding (about $13.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Heat Wave carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Leavenworth County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 208 paid claims, totaling $3.0M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $14.3K 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. Leavenworth County's 23 federal records stand 28% above the Kansas county mean of 18.0. 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, 66.3/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $34.5M in annualized losses), and a Very Low social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Heat Wave carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at 15 modeled event-days per year here, based on 171 historical events on record.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 23 entries for Leavenworth County, including 18 Major Disaster records, 28% above the Kansas county mean. Across the 53-year span, that works out to 0.4 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 Leavenworth 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 |
|---|---|---|
| Heat Wave | Relatively Moderate | 15 modeled event-days per year |
| Ice Storm | Relatively High | an average of 1.2 times per year |
| Winter Weather | Relatively High | an average of 11 times per year |
| Tornado | Relatively Moderate | roughly once every 3 years |
| Hail | Relatively Moderate | an average of 9.8 times per year |
| Strong Wind | Relatively High | an average of 7.3 times per year |
| Cold Wave | Relatively Moderate | an average of 2.5 times per year |
| Landslide | Relatively Low | roughly once every 5 years |
| Riverine Flooding | Relatively Low | an average of 3.7 times per year |
| Wildfire | Very Low | roughly once every 1,325 years |
| Lightning | Relatively Moderate | an average of 50 times per year |
| Drought | Relatively Low | 15 modeled event-days per year |
| Earthquake | Very Low | roughly once every 961 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Leavenworth County's record, 52% 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: Heat Wave
Heat Wave is measured in event-days per year rather than discrete events, and it is the hazard whose harm is most consistently undercounted: its toll is health and mortality, concentrated among people without cooling, rather than visible damage to property.
Worth noting for Leavenworth County: the model and the federal record do NOT point at the same hazard. Heat Wave 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.
