The verdict

Two federal records point in the busier direction for Duval County. Its 41 FEMA declarations are 2% above the Florida county mean and exceed the count for 97% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 3%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Duval County is led by Riverine Flooding (about $134.4M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Cold Wave carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Duval County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 6,061 claims and $214.7M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $35.4K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.

The declaration register points in the busier direction. Duval County's 41 federal records stand 2% above the Florida county mean of 40.4. 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.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 97.2/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $263.9M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Cold Wave stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 3 times per year here, based on 56 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 41 entries for Duval County, including 24 Major Disaster records, 2% above the Florida county mean. Across the 56-year span, that works out to 0.7 declarations a year. Hurricane leads the file with 22 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Duval 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.

Cold Wave Relatively High an average of 3 times per year
Lightning Very High an average of 71 times per year
Hurricane Relatively High roughly once every 4 years
Riverine Flooding Relatively High an average of 3.5 times per year
Heat Wave Relatively High 4.6 modeled event-days per year
Hail Relatively High an average of 1.8 times per year
Tornado Relatively High roughly once every 2 years
Coastal Flooding Relatively High an average of 2.8 times per year
Earthquake Relatively Moderate roughly once every 950 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Duval County's federal record, 54% 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: Cold Wave

Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.

Worth noting for Duval County: the model and the federal record do NOT point at the same hazard. Cold Wave carries the highest modeled rating (Relatively High), 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.

Duval County's closest FEMA peer: Orange County, CA

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

Duval County, FL has 41 federal declaration records, 2% more than the Florida county mean of 40; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 24 of 41 records; the category describes past federal action, not the next likely hazard. Florida overview
  • The state benchmark and national rank point the same way: this count tops the Florida mean and the totals for 97% of 3,266 U.S. counties. Most-disaster rankings
  • The large NFIP claims file and FEMA declaration history measure different federal records; the guide explains where they overlap and where they do not. 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.
