The verdict

Cass County has a nationally busy FEMA history: 21 declarations, more than 52% of counties in this registry. But the state comparison tempers that reading: the total is 15% below the Missouri county mean. FEMA's separate National Risk Index places the county in the riskiest 25%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Cass County is led by Riverine Flooding (about $17.5M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Cass County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 328 paid claims, totaling $5.4M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $16.5K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Missouri county averages 24.6 federal declaration records, while Cass County has 21. The gap is 15% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

FEMA National Risk Index

This county carries a high composite score on FEMA's National Risk Index, 74.9/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $44.3M in annualized losses), and a Very Low social-vulnerability profile combined with Relatively Moderate community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 8.2 times per year here, based on 310 historical events on record.

How often does each hazard strike Cass 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 Moderate an average of 8.2 times per year
Strong Wind Relatively High an average of 6.1 times per year
Tornado Relatively Moderate roughly once every 2 years
Heat Wave Relatively Moderate 15 modeled event-days per year
Cold Wave Relatively Moderate an average of 2.1 times per year
Winter Weather Relatively Moderate an average of 11 times per year
Ice Storm Relatively Moderate roughly once every 1 years
Riverine Flooding Relatively Low an average of 1.8 times per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Cass County's record, 48% 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 Cass County the two measures on this page point the same way: Hail is the county's highest-rated modeled hazard (Relatively Moderate), 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.

Data-matched county comparisons

Cass County's closest FEMA peer: Yates County, NY

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Cass County. Record similarity, not a safety rating.

How these peers are chosen

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.
