The verdict

Two federal records point in the busier direction for Lamoille County. Its 38 FEMA declarations are 32% above the Vermont county mean and exceed the count for 95% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 18%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Lamoille County is led by Riverine Flooding (about $8.3M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Winter Weather carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Lamoille County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 174 paid claims, totaling $5.7M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $32.5K 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. Lamoille County's 38 federal records stand 32% above the Vermont county mean of 28.8. 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.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 38 entries for Lamoille County, including 32 Major Disaster records, 32% above the Vermont county mean. Across the 51-year span, that works out to 0.7 declarations a year. Severe Storm leads the file with 19 entries. Declaration type records the federal action taken, not every assistance program approved.

FEMA National Risk Index

This county's FEMA National Risk Index composite lands at 18.3/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $10.6M in annualized losses), tempered or compounded by a Very Low social-vulnerability score and Very High community-resilience score. Among the 18 modeled hazards, Winter Weather carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 23 times per year here, based on 433 historical events on record.

How often does each hazard strike Lamoille 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.

Winter Weather Relatively Moderate an average of 23 times per year
Landslide Relatively Low roughly once every 1 years
Hurricane Relatively Low roughly once every 35 years
Avalanche Very Low roughly once every 100 years
Riverine Flooding Relatively Low an average of 1.6 times per year
Earthquake Very Low roughly once every 659 years
Ice Storm Relatively Low roughly once every 4 years
Lightning Relatively Low an average of 23 times per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Lamoille County's record, 50% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.

These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.

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: Winter Weather

Winter Weather in the model means the accumulation of snow and cold that disrupts rather than destroys: road closures, roof loads, burst pipes and lost heating. Its costs land heavily on transport and on households least able to absorb an interruption.

Worth noting for Lamoille County: the model and the federal record do NOT point at the same hazard. Winter Weather carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Severe Storm. 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

Lamoille County's closest FEMA peer: Pembina County, ND

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Lamoille 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 Lamoille County

Lamoille County, VT has 38 federal declaration records, 32% more than the Vermont county mean of 29; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 32 of 38 records; the category describes past federal action, not the next likely hazard. Vermont overview
  • The state benchmark and national rank point the same way: this count tops the Vermont mean and the totals for 95% of 3,266 U.S. counties. 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

An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
