What does Glacier County's hazard record show?

FEMA National Risk Index

This county carries a high composite score on FEMA's National Risk Index, 51.5/100, rated Relatively Low. Its Expected Annual Loss rating is Very Low (roughly $9.8M in annualized losses), and a Very High social-vulnerability profile combined with Relatively Low community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Cold Wave stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 9 times per year here, based on 171 historical events on record.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 8 claims and $32.2K 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. Glacier 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 Glacier 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
Cold Wave Relatively High an average of 9 times per year
Winter Weather Relatively High an average of 43 times per year
Wildfire Relatively Low roughly once every 746 years
Avalanche Relatively Moderate roughly once every 30 years
Landslide Relatively Low an average of 1.5 times per year
Earthquake Relatively Low roughly once every 361 years
Lightning Relatively Low an average of 18 times per year
Riverine Flooding Relatively Low roughly once every 4 years
Drought Relatively Low 47 modeled event-days per year
Heat Wave Very Low 0.5 modeled event-days per year
Strong Wind Very Low roughly once every 5 years
Ice Storm Very Low roughly once every 67 years

What Flood declarations mean here

Flood is the most frequent declaration type on Glacier County's record, 25% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.

Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.

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: Cold Wave

Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.

Worth noting for Glacier County: the model and the federal record do NOT point at the same hazard. Cold Wave carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. 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

Glacier County's closest FEMA peer: Thomas County, KS

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