18 FEMA disaster declarations (1972-2020), with a FEMA National Risk Index rating of Relatively Low. Most common hazard: Flood.
The verdict
Blair 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 3% below the Pennsylvania county mean. FEMA's separate National Risk Index places the county in the riskiest 22%; that score models loss and vulnerability rather than counting declarations.
FEMA's National Risk Index and its declaration registry are separate measures. This county's registry includes Major Disaster (DR) and Emergency (EM) records; an EM authorizes a narrower set of federal assistance than a DR.

FEMA's modeled annual dollar loss for Blair County is led by Riverine Flooding (about $27.3M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Winter Weather carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

FEMA's NFIP table contains a substantial paid-claim history for this county: 1,115 claims and $8.5M 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 $7.6K. 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 Blair County has 18. The gap is 3% 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.
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 77.7/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $33.9M 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, Winter Weather stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 14 times per year here, based on 265 historical events on record.
Nationally, Blair County's 18 FEMA records form a high-volume history; within Pennsylvania, however, the count is 3% below the county mean. 12 entries carry the Major Disaster classification. The largest incident group is Flood, appearing 6 times. The full 48-year record averages 0.4 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

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 |
|---|---|---|
| Winter Weather | Relatively High | an average of 14 times per year |
| Riverine Flooding | Relatively Moderate | an average of 1.5 times per year |
| Landslide | Relatively Low | roughly once every 2 years |
| Hurricane | Relatively Low | roughly once every 21 years |
| Lightning | Relatively Moderate | an average of 37 times per year |
| Strong Wind | Relatively Moderate | an average of 2.8 times per year |
| Earthquake | Relatively Low | roughly once every 1,852 years |
| Avalanche | Very Low | roughly once every 100 years |
| Tornado | Relatively Low | roughly once every 6 years |
| Cold Wave | Relatively Low | an average of 1.8 times per year |
| Hail | Relatively Low | an average of 1.6 times per year |
| Heat Wave | Relatively Low | 1.3 modeled event-days per year |
| Wildfire | Very Low | roughly once every 10,202 years |
| Ice Storm | Very Low | roughly once every 10 years |

Flood is the most frequent declaration type on Blair County's record, 33% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.
Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.
Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.
FEMA categorizes declarations as Major Disasters (DR), Emergencies (EM), or Fire Management Assistance (FM).

Winter Weather in the model means the accumulation of snow and cold that disrupts rather than destroys: road closures, roof loads, burst pipes and lost heating. Its costs land heavily on transport and on households least able to absorb an interruption.
Worth noting for Blair County: the model and the federal record do NOT point at the same hazard. Winter Weather carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. 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.

Understanding disaster data
Blair County's NFIP claims file (1,115 claims) and FEMA declaration history measure different federal records - this guide separates them from modeled NRI risk.
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 Blair County
Against a Pennsylvania county mean of 19 declarations, Blair County, PA records 18, or 3% fewer. PlainHazard classifies that historical total as high activity.
A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
PlainHazard derives this profile from FEMA's Disaster Declarations Summaries and National Risk Index data. The declaration comparison covers 3,266 U.S. counties and county equivalents in this database, refreshed as of 2026-08-03. Read our methodology - how this data is sourced, computed, and verified.
