Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Western District is led by Tsunami (about $6.9M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Coastal Flooding carries the highest National Risk Index rating (null). EAL and risk score use different inputs; they need not agree.

What does Western District's hazard record show?

Even the county's top-rated hazard, Coastal Flooding, only reaches on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 3 years here.

Reading the federal records together

No paid-claim row for this county appears in the NFIP county table used by PlainHazard. That absence is not evidence that flooding never occurred: the register observes claims under federal flood-insurance policies, not uninsured losses, emergency reports, or every flood outside the program. The FEMA declaration history below is therefore the available federal-action record on this page.

The declaration register points in the busier direction. Western District's 16 federal records stand 7% above the American Samoa county mean of 15.0. 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 Western District?

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. These modeled frequencies are not forecasts.

Hazard NRI Risk Rating Recurrence
Coastal Flooding roughly once every 3 years
Earthquake roughly once every 129 years
Hurricane roughly once every 13 years
Riverine Flooding an average of 3.1 times per year
Tsunami roughly once every 3 years
Volcanic Activity roughly once every 3,333 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Western District's federal record, 31% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.

One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.

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: Coastal Flooding

Coastal Flooding is modeled separately from riverine flooding because its driver is different: surge, tide and wave action rather than a watershed draining. It is also the hazard whose baseline is moving, since the same storm rides on a higher starting sea level than it used to.

For Western District the two measures on this page point the same way: Coastal Flooding is the county's highest-rated modeled hazard, and Hurricane 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

Western District's closest FEMA peer: Divide County, ND

Comparisons use published FEMA declaration fields for Western District. 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.

Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.

Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.

This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.
