The verdict

Two federal records point in the busier direction for Greene County. Its 26 FEMA declarations are 27% above the 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 9%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Greene County is led by Riverine Flooding (about $3.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Hurricane carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Greene County's hazard record show?

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 26 entries for Greene County, including 19 Major Disaster records, 27% above the Virginia county mean. Across the 54-year span, that works out to 0.5 declarations a year. Hurricane leads the file with 6 entries. Declaration type records the federal action taken, not every assistance program approved.

FEMA National Risk Index

FEMA's National Risk Index places this county in the low end of the national distribution, composite score 9.3/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.7M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively Low) and community resilience (Relatively Low). 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 15 years here, based on 18 historical events on record.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 28 claims and $230.8K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

The declaration register points in the busier direction. Greene County's 26 federal records stand 27% 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.

How often does each hazard strike Greene 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 15 years
Drought Relatively Low 3.7 modeled event-days per year
Avalanche Very Low roughly once every 100 years
Landslide Very Low roughly once every 3 years
Wildfire Very Low roughly once every 1,018 years
Earthquake Very Low roughly once every 533 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Greene County's federal record, 23% 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 Greene 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

Greene County's closest FEMA peer: Edmonson County, KY

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

Greene County, VA has 26 federal declaration records, 27% more than the Virginia county mean of 20; 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. Virginia overview
  • The state benchmark and national rank point the same way: this count tops the Virginia mean and the totals for 75% of 3,266 U.S. counties. Most-disaster rankings
  • A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. 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.
