Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Jefferson County is led by Riverine Flooding (about $2.2M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Drought carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Jefferson County's hazard record show?

FEMA National Risk Index

This county's FEMA National Risk Index composite lands at 25.8/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $6.6M in annualized losses), tempered or compounded by a Relatively High social-vulnerability score and Relatively Low community-resilience score. Among the 18 modeled hazards, Drought carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at 50 modeled event-days per year here, based on 1,533 historical events on record.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 2 claims and $11.4K 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. Jefferson County's 19 federal records stand 9% above the Georgia county mean of 17.4. 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 Jefferson 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
Drought Relatively Moderate 50 modeled event-days per year
Hurricane Relatively Low roughly once every 11 years
Earthquake Relatively Low roughly once every 402 years
Ice Storm Relatively Low roughly once every 1 years
Heat Wave Relatively Low 7.3 modeled event-days per year
Wildfire Very Low roughly once every 1,579 years
Tornado Relatively Low roughly once every 4 years
Strong Wind Relatively Low an average of 2.5 times per year
Hail Relatively Low an average of 2.3 times per year
Riverine Flooding Very Low roughly once every 9 years
Lightning Very Low an average of 63 times per year
Cold Wave Very Low roughly once every 4 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Jefferson County's federal record, 32% 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: Drought

Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.

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

Jefferson County's closest FEMA peer: Gillespie County, TX

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