Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Amherst County is led by Riverine Flooding (about $4.4M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hurricane carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Amherst County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 53 paid claims, totaling $756.5K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $14.3K 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. Amherst County's 23 federal records stand 13% above the Virginia county mean of 20.4. 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's FEMA National Risk Index composite lands at 21.0/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $6.5M in annualized losses), tempered or compounded by a Relatively Moderate social-vulnerability score and Relatively Moderate community-resilience score. Even the county's top-rated hazard, Hurricane, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 16 years here, based on 20 historical events on record.

How often does each hazard strike Amherst 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.

Hurricane Relatively Low roughly once every 16 years
Landslide Relatively Low an average of 1.2 times per year
Strong Wind Relatively Moderate an average of 3 times per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Amherst County's federal record, 26% 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: Hurricane

Hurricane exposure in the model bundles the three ways a tropical system does harm, which arrive on different timescales and are insured differently: wind, storm surge on the coast, and rainfall flooding that can reach far inland well after landfall.

For Amherst County the two measures on this page point the same way: Hurricane is the county's highest-rated modeled hazard (Relatively Low), 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

Amherst County's closest FEMA peer: Boone County, AR

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