Jerome County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Jerome County is led by Riverine Flooding (about $2.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Wildfire carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Jerome County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 21.5/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $5.8M in annualized losses), tempered or compounded by a Relatively High social-vulnerability score and Very Low community-resilience score. Among the 18 modeled hazards, Wildfire carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 141 years here.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 1 claim and $0 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.
Start with the state benchmark: a Idaho county averages 8.3 federal declaration records, while Jerome County has 6. The gap is 28% 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.

How often does each hazard strike Jerome 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 Moderate | roughly once every 141 years |
| Winter Weather | Relatively High | an average of 9.8 times per year |
| Heat Wave | Relatively Low | 3.6 modeled event-days per year |
| Earthquake | Very Low | roughly once every 351 years |
| Volcanic Activity | Very Low | roughly once every 2,500 years |
| Ice Storm | Relatively Low | roughly once every 14 years |
| Avalanche | Very Low | roughly once every 100 years |
| Riverine Flooding | Very Low | roughly once every 7 years |
| Cold Wave | Relatively Low | roughly once every 5 years |
| Lightning | Relatively Low | an average of 19 times per year |
| Drought | Very Low | 60 modeled event-days per year |
| Strong Wind | Relatively Low | roughly once every 2 years |
| Landslide | Very Low | roughly once every 17 years |
| Tornado | Very Low | roughly once every 18 years |
| Hail | Very Low | roughly once every 4 years |

What Biological declarations mean here
Biological is the most frequent declaration type on Jerome County's record, 33% of its declarations. In practice this category is dominated by the COVID-19 declarations of 2020, which were issued across every US state and territory rather than in response to any local hazard event.
This has a direct consequence for how Jerome County's number should be read. Because those declarations reached essentially every county in the country, they raise every county's total by a similar amount and tell you nothing about local hazard exposure. A county whose record is led by Biological declarations is, in most cases, a county with a genuinely quiet weather-hazard history, the pandemic records are simply the largest thing in an otherwise short list.
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 Jerome County: the model and the federal record do NOT point at the same hazard. Wildfire carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Biological. 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.
