Teton County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Teton County is led by Riverine Flooding (about $4.3M Expected Annual Loss, Historical Loss Ratio Relatively High), while Avalanche carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Teton County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 19.0/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $8.2M in annualized losses), tempered or compounded by a Relatively Low social-vulnerability score and Relatively Moderate community-resilience score. Among the 18 modeled hazards, Avalanche carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 30 years here, based on 1 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 5 claims and $30.7K 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. Teton County's 12 federal records stand 9% above the Montana county mean of 11.0. 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 Teton 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 |
|---|---|---|
| Avalanche | Relatively Moderate | roughly once every 30 years |
| Wildfire | Relatively Low | roughly once every 1,538 years |
| Cold Wave | Relatively Moderate | an average of 8.1 times per year |
| Winter Weather | Relatively Moderate | an average of 41 times per year |
| Earthquake | Very Low | roughly once every 274 years |
| Landslide | Very Low | roughly once every 1 years |
| Drought | Relatively Low | 60 modeled event-days per year |
| Riverine Flooding | Very Low | roughly once every 3 years |
| Strong Wind | Very Low | roughly once every 2 years |
| Heat Wave | Very Low | 0.7 modeled event-days per year |
| Hail | Very Low | roughly once every 1 years |
| Lightning | Very Low | an average of 20 times per year |
| Tornado | Very Low | roughly once every 15 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Teton County's record, 25% 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: Avalanche
Avalanche is the most geographically restricted hazard in the model, limited to steep terrain holding seasonal snow. Its exposure concentrates on mountain roads, rail corridors and backcountry recreation rather than on the built environment generally.
Worth noting for Teton County: the model and the federal record do NOT point at the same hazard. Avalanche 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.
