Allegany County's FEMA Risk Index score
What does Allegany County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 193 paid claims, totaling $714.8K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $3.7K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
The declaration register points in the busier direction. Allegany County's 25 federal records stand 2% above the New York county mean of 24.5. 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 carries a high composite score on FEMA's National Risk Index, 69.8/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $26.9M in annualized losses), and a Relatively Moderate social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Riverine Flooding carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 1.6 times per year here, based on 45 historical events on record.

How often does each hazard strike Allegany 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 |
|---|---|---|
| Riverine Flooding | Relatively Moderate | an average of 1.6 times per year |
| Landslide | Relatively Low | roughly once every 1 years |
| Strong Wind | Relatively Moderate | an average of 1.8 times per year |
| Hurricane | Relatively Low | roughly once every 42 years |
| Lightning | Relatively Moderate | an average of 31 times per year |
| Tornado | Relatively Low | roughly once every 5 years |
| Cold Wave | Relatively Low | an average of 4.1 times per year |
| Ice Storm | Relatively Low | roughly once every 3 years |
| Winter Weather | Relatively Low | an average of 20 times per year |
| Earthquake | Very Low | roughly once every 2,451 years |
| Avalanche | Very Low | roughly once every 100 years |
| Hail | Very Low | an average of 1.1 times per year |
| Drought | Very Low | 0.3 modeled event-days per year |

What Flood declarations mean here
Flood is the most frequent declaration type on Allegany County's record, 28% 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.

The model's sharpest exposure here: Riverine Flooding
Riverine Flooding is the model's measure of a watershed draining more water than its channel can carry. Unlike flash flooding it usually builds over days and is forecast in advance, which makes it the hazard where warning time most reliably converts into reduced harm.
For Allegany County the two measures on this page point the same way: Riverine Flooding is the county's highest-rated modeled hazard (Relatively Moderate), and Flood declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
