The verdict

Start with the local benchmark for Nye County: 5 FEMA declaration records are 60% below the Nevada county mean, even though the count is higher than 2% of counties in the national registry. On FEMA's distinct National Risk Index model, which combines expected loss with vulnerability and resilience, the county ranks in the riskiest 22%.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Nye County is led by Riverine Flooding (about $13.4M Expected Annual Loss, Historical Loss Ratio Very Low), while Heat Wave carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Nye County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 136 paid claims, totaling $1.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $9.9K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Nevada county averages 12.4 federal declaration records, while Nye County has 5. The gap is 60% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 78.3/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $24.5M in annualized losses). Social vulnerability reads Very High and community resilience Very Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Heat Wave stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at 4.4 modeled event-days per year here, based on 44 historical events on record.

Declaration frequency

The state comparison is the clearest context for Nye County's moderate federal record. Its 5 declarations sit 60% below the Nevada county mean, with 1 Major Disaster entries among them. 2 records concern Snowstorm, the file's most frequent incident type. Spread across 15 years, the registry rate is 0.3 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.

How often does each hazard strike Nye 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
Heat Wave Relatively High 4.4 modeled event-days per year
Earthquake Relatively Moderate roughly once every 25 years
Lightning Relatively High an average of 26 times per year
Riverine Flooding Relatively Moderate an average of 1.8 times per year
Wildfire Relatively Low roughly once every 1,512 years
Avalanche Relatively Low roughly once every 30 years
Winter Weather Relatively Moderate an average of 9.5 times per year
Landslide Very Low an average of 13 times per year
Drought Relatively Low 128 modeled event-days per year
Strong Wind Relatively Low roughly once every 11 years
Volcanic Activity Very Low roughly once every 1,667 years
Cold Wave Very Low roughly once every 8 years
Hail Very Low roughly once every 71 years
Tornado Very Low roughly once every 7 years

What Snowstorm declarations mean here

Snowstorm is the most frequent declaration type on Nye County's record, 40% of its declarations. Snow-related declarations work on a narrower basis than most other hazards: they are generally issued to reimburse the cost of snow removal and emergency protective measures, rather than to repair destroyed property.

The qualifying test is unusual too. FEMA assesses snowfall against record levels for the affected area, so the same storm total can qualify in a county where it is historically extreme and not qualify a few hundred miles north where it is an ordinary winter. A low snowstorm declaration count is therefore not evidence of mild winters.

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: Heat Wave

Heat Wave is measured in event-days per year rather than discrete events, and it is the hazard whose harm is most consistently undercounted: its toll is health and mortality, concentrated among people without cooling, rather than visible damage to property.

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

Nye County's closest FEMA peer: Eau Claire County, WI

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

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.

Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.

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.

What this means for Nye County

Against a Nevada county mean of 12 declarations, Nye County, NV records 5, or 60% fewer. PlainHazard classifies that historical total as moderate activity.

  • Emergency is the largest group (4 of 5) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Nevada overview
  • Nationally the county exceeds 2% of recorded county totals, but its own Nevada benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
  • Use the data guide to separate this mid-volume insurance-claims file from declaration counts and modeled NRI risk. Disaster-data guide

A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
