Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Flathead County is led by Riverine Flooding (about $23.8M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Avalanche carries the highest National Risk Index rating (Very High). EAL and risk score use different inputs; they need not agree.

What does Flathead County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 132 paid claims, totaling $690.3K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $5.2K 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. Flathead County's 15 federal records stand 37% 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.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 86.5/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $75.4M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively Moderate, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Avalanche stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at roughly once every 2 years here, based on 15 historical events on record.

How often does each hazard strike Flathead 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 Very High roughly once every 2 years
Landslide Relatively Moderate an average of 4.2 times per year
Earthquake Relatively Moderate roughly once every 33 years
Wildfire Relatively Moderate roughly once every 301 years
Cold Wave Relatively High an average of 4.2 times per year
Winter Weather Relatively High an average of 50 times per year
Riverine Flooding Relatively Moderate an average of 1 time per year
Ice Storm Relatively Moderate roughly once every 67 years
Lightning Relatively Moderate an average of 21 times per year
Heat Wave Relatively Low 1.3 modeled event-days per year
Drought Very Low 36 modeled event-days per year

What Fire declarations mean here

Fire is the most frequent declaration type on Flathead County's record, 33% of its declarations. Wildfire is the one hazard here with its own dedicated federal instrument: the Fire Management Assistance Grant, which appears in this data as an FM record. An FMAG can be authorised while a fire is still burning, on a timescale of hours, because its purpose is to reimburse the cost of fighting a fire that threatens to become a major disaster.

That distinction matters when comparing counties. An FM declaration is not a presidential major disaster declaration and does not carry the same assistance programmes, so a fire-heavy county's total is not directly comparable with a hurricane-heavy county's total unless the declaration types are separated, which is why they are listed separately on this page.

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 Flathead County: the model and the federal record do NOT point at the same hazard. Avalanche carries the highest modeled rating (Very High), while the county's declaration history is led by Fire. 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.

Data-matched county comparisons

Flathead County's closest FEMA peer: Mariposa County, CA

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Flathead 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.
