The verdict

Erie County has a nationally busy FEMA history: 11 declarations, more than 12% of counties in this registry. But the state comparison tempers that reading: the total is 41% below the Pennsylvania county mean. FEMA's separate National Risk Index places the county in the riskiest 16%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Erie County is led by Riverine Flooding (about $38.2M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Lightning carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Erie County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 511 claims and $6.0M 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 $11.7K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.

Start with the state benchmark: a Pennsylvania county averages 18.6 federal declaration records, while Erie County has 11. The gap is 41% 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.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 84.1/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Low (roughly $47.6M in annualized losses). Social vulnerability reads Relatively Moderate and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Lightning stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 37 times per year here, based on 256,121 historical events on record.

Declaration frequency

Nationally, Erie County's 11 FEMA records form a high-volume history; within Pennsylvania, however, the count is 41% below the county mean. 6 entries carry the Major Disaster classification. The largest incident group is Hurricane, appearing 3 times. The full 48-year record averages 0.2 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Erie 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
Lightning Relatively High an average of 37 times per year
Winter Weather Relatively High an average of 30 times per year
Strong Wind Relatively High an average of 1.3 times per year
Riverine Flooding Relatively Moderate an average of 2.1 times per year
Hurricane Relatively Low roughly once every 33 years
Ice Storm Relatively Moderate an average of 1.3 times per year
Tornado Relatively Moderate roughly once every 3 years
Earthquake Relatively Low roughly once every 1,274 years
Hail Relatively Low an average of 1.6 times per year
Landslide Very Low roughly once every 4 years
Heat Wave Relatively Low 0.9 modeled event-days per year
Cold Wave Relatively Low an average of 3.6 times per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Erie County's federal record, 27% 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: Lightning

Lightning is modeled as a high-frequency, low-per-event hazard: strike counts are large, but each strike affects a very small area. Its aggregate cost accumulates through structure fires, electrical and electronic damage, and it is one of the few hazards whose risk is essentially continuous through the season rather than episodic.

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

Data-matched county comparisons

Erie County's closest FEMA peer: Rock Island County, IL

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

Against a Pennsylvania county mean of 19 declarations, Erie County, PA records 11, or 41% fewer. PlainHazard classifies that historical total as high activity.

  • Major Disaster is the largest group (6 of 11) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Pennsylvania overview
  • Nationally the county exceeds 12% of recorded county totals, but its own Pennsylvania benchmark is higher. The ranking keeps those two contexts separate. 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
