The verdict
Two federal records point in the busier direction for Broome County. Its 30 FEMA declarations are 22% above the New York county mean and exceed the count for 86% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 13%, based on modeled expected annual loss, social vulnerability, and community resilience.

What does Broome County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 3,100 claims and $138.3M 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 $44.6K. 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. Broome County's 30 federal records stand 22% 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 87.5/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $60.1M in annualized losses). Social vulnerability reads Relatively Moderate and community resilience Very High, both critical modifiers of realized harm here. 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 3.4 times per year here, based on 96 historical events on record.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 30 entries for Broome County, including 20 Major Disaster records, 22% above the New York county mean. Across the 54-year span, that works out to 0.6 declarations a year. Severe Storm leads the file with 9 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Broome 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 3.4 times per year |
| Winter Weather | Relatively High | an average of 16 times per year |
| Lightning | Relatively High | an average of 31 times per year |
| Tornado | Relatively Moderate | roughly once every 5 years |
| Hurricane | Relatively Low | roughly once every 36 years |
| Landslide | Relatively Low | roughly once every 1 years |
| Ice Storm | Relatively Moderate | roughly once every 2 years |
| Cold Wave | Relatively Moderate | an average of 3.7 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Broome County's record, 30% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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.
Worth noting for Broome County: the model and the federal record do NOT point at the same hazard. Riverine Flooding carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Severe Storm. 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.

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 Broome County
Broome County, NY has 30 federal declaration records, 22% more than the New York county mean of 25; its history sits in PlainHazard's high activity band.
- Within this above-state-average declaration file, major disaster leads with 20 of 30 records; the category describes past federal action, not the next likely hazard. New York overview
- The state benchmark and national rank point the same way: this count tops the New York mean and the totals for 86% 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.
