The verdict

Two federal records point in the busier direction for Roane County. Its 26 FEMA declarations are 8% above the West Virginia county mean and exceed the count for 75% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 45%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Roane County is led by Riverine Flooding (about $8.8M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Landslide carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Roane County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 189 paid claims, totaling $3.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $17.6K 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. Roane County's 26 federal records stand 8% above the West Virginia county mean of 24.2. 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

FEMA's data shows an elevated National Risk Index composite of 45.0/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $9.9M in annualized losses). Social vulnerability (Very High) and community resilience (Relatively Low) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Landslide carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 1.4 times per year here.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 26 entries for Roane County, including 19 Major Disaster records, 8% above the West Virginia county mean. Across the 33-year span, that works out to 0.8 declarations a year. Severe Storm leads the file with 10 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Roane 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.

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Roane County's record, 38% 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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Roane County: the model and the federal record do NOT point at the same hazard. Landslide 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.

Roane County's closest FEMA peer: Greene County, VA

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

Roane County, WV has 26 federal declaration records, 8% more than the West Virginia county mean of 24; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 19 of 26 records; the category describes past federal action, not the next likely hazard. West Virginia overview
  • The state benchmark and national rank point the same way: this count tops the West Virginia mean and the totals for 75% of 3,266 U.S. counties. Most-disaster rankings
