Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Pasco County is led by Hurricane (about $77.7M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Tornado carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Pasco County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 14,541 claims and $692.2M 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 $47.6K. 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. Pasco County's 44 federal records stand 9% 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 96.0/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $199.3M in annualized losses). Social vulnerability reads Relatively Low and community resilience Very Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Tornado stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 1 years here, based on 55 historical events on record.

How often does each hazard strike Pasco 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.

Tornado Relatively High roughly once every 1 years
Hurricane Very High roughly once every 4 years
Lightning Very High an average of 94 times per year
Riverine Flooding Relatively High an average of 1.8 times per year
Wildfire Relatively Moderate roughly once every 189 years
Coastal Flooding Relatively High an average of 3.7 times per year
Heat Wave Relatively Moderate 2.9 modeled event-days per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Pasco County's federal record, 48% 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: Tornado

Tornado exposure is the most spatially concentrated in the model: total destruction along a narrow corridor with intact property either side. County-level averages therefore understate severity badly for anyone actually in the path, and overstate it for everyone else.

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

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.

Which natural hazard poses the greatest risk to Pasco County?
Based on FEMA NRI data, the highest-risk natural hazard in Pasco County as of the latest release is Tornado (risk rating: Relatively High). Other significant hazards include Hurricane (Very High) and Lightning (Very High). FEMA's modeled event frequency puts tornado here at roughly once every 1 years, drawn from 55 historical events on record. These scores are based on FEMA's analysis of historical event frequency, exposed assets, and community vulnerability.
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.
