Atchison County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Atchison County is led by Riverine Flooding (about $3.9M Expected Annual Loss, Historical Loss Ratio Relatively High), while Wildfire carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Atchison County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 16.0/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $9.4M in annualized losses), tempered or compounded by a Very Low social-vulnerability score and Relatively High community-resilience score. Even the county's top-rated hazard, Wildfire, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 531 years here.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 3 claims and $31.4K 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. Atchison County's 19 federal records stand 6% 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.

How often does each hazard strike Atchison 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 |
|---|---|---|
| Wildfire | Relatively Low | roughly once every 531 years |
| Hail | Relatively Low | an average of 9.4 times per year |
| Ice Storm | Relatively Moderate | roughly once every 1 years |
| Landslide | Very Low | roughly once every 8 years |
| Drought | Relatively Low | 19 modeled event-days per year |
| Heat Wave | Relatively Low | 13 modeled event-days per year |
| Tornado | Relatively Low | roughly once every 3 years |
| Winter Weather | Relatively Low | an average of 11 times per year |
| Strong Wind | Relatively Low | an average of 7 times per year |
| Lightning | Relatively Low | an average of 50 times per year |
| Earthquake | Very Low | roughly once every 1,189 years |
| Cold Wave | Very Low | an average of 3.1 times per year |
| Riverine Flooding | Very Low | an average of 1.9 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Atchison County's record, 53% 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: Wildfire
Wildfire risk in the model reflects fuel, terrain, weather and how much development sits in the wildland-urban interface. It is one of the few hazards where the exposure is materially changed by land management and building choices, not only by where the county happens to be.
Worth noting for Atchison County: the model and the federal record do NOT point at the same hazard. Wildfire carries the highest modeled rating (Relatively Low), 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.
