The verdict

Sussex County has a nationally busy FEMA history: 18 declarations, more than 37% of counties in this registry. But the state comparison tempers that reading: the total is 12% below the Virginia county mean. FEMA's separate National Risk Index places the county safer than 13%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Sussex County is led by Riverine Flooding (about $1.6M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Drought carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Sussex County's hazard record show?

FEMA National Risk Index

FEMA's National Risk Index places this county in the low end of the national distribution, composite score 13.2/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.1M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively High) and community resilience (Relatively Moderate). 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 5.8 modeled event-days per year here, based on 168 historical events on record.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 34 claims and $143.5K 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.

Start with the state benchmark: a Virginia county averages 20.4 federal declaration records, while Sussex County has 18. The gap is 12% 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.

How often does each hazard strike Sussex 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 5.8 modeled event-days per year
Hurricane Relatively Low roughly once every 5 years
Earthquake Very Low roughly once every 686 years
Winter Weather Relatively Low an average of 4.6 times per year
Heat Wave Very Low 6.3 modeled event-days per year
Ice Storm Relatively Low an average of 1.2 times per year
Hail Very Low an average of 2.5 times per year
Strong Wind Relatively Low roughly once every 2 years
Tornado Very Low roughly once every 3 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Sussex County's federal record, 44% 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 Sussex 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

Sussex County's closest FEMA peer: Jack County, TX

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