The verdict
Union County has a nationally busy FEMA history: 13 declarations, more than 17% of counties in this registry. But the state comparison tempers that reading: the total is 11% below the Ohio county mean. FEMA's separate National Risk Index places the county safer than 33%; that score models loss and vulnerability rather than counting declarations.

Union County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Union County is led by Riverine Flooding (about $12.9M Expected Annual Loss, Historical Loss Ratio Relatively High), while Ice Storm carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Union County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 56 paid claims, totaling $430.1K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $7.7K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a Ohio county averages 14.6 federal declaration records, while Union County has 13. The gap is 11% 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
FEMA's data shows an elevated National Risk Index composite of 32.7/100 for this county (Very Low rating). Expected Annual Loss comes in at Relatively Low (roughly $19.0M in annualized losses). Social vulnerability (Very Low) and community resilience (Very High) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Ice Storm carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 1 years here, based on 47 historical events on record.

How often does each hazard strike Union 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 |
|---|---|---|
| Ice Storm | Relatively Moderate | roughly once every 1 years |
| Hail | Relatively Low | an average of 3.5 times per year |
| Winter Weather | Relatively Low | an average of 12 times per year |
| Riverine Flooding | Relatively Low | an average of 1.5 times per year |
| Tornado | Relatively Low | roughly once every 4 years |
| Heat Wave | Relatively Low | 3.6 modeled event-days per year |
| Earthquake | Very Low | roughly once every 722 years |
| Lightning | Relatively Low | an average of 45 times per year |
| Drought | Relatively Low | 0.3 modeled event-days per year |
| Strong Wind | Relatively Low | an average of 2.4 times per year |
| Landslide | Very Low | roughly once every 15 years |
| Hurricane | Very Low | roughly once every 145 years |
| Cold Wave | Very Low | an average of 4.8 times per year |
| Wildfire | Very Low | roughly once every 33,671 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Union County's record, 46% 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: Ice Storm
Ice storms load power lines and tree limbs with accumulating freezing rain until they fail. The characteristic cost is infrastructure and multi-day power loss across a wide area rather than structural damage to buildings, which is why their consequences often outlast the weather that caused them.
Worth noting for Union County: the model and the federal record do NOT point at the same hazard. Ice Storm 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.

How many flood insurance claims has Union County filed?
Union County has 56 National Flood Insurance Program (NFIP) claims totaling $430.1K in payments, with an average of $7.7K per claim.
Does FEMA's top risk-rated hazard match the highest Expected Annual Loss in Union County?
No. In Union County, Ice Storm has the highest National Risk Index rating (Relatively Moderate), while Riverine Flooding leads Expected Annual Loss at about $12.9M. FEMA's risk score and dollar-loss model use different inputs, so the leaders often differ.
What was the worst year for disasters in Union County?

What is the FEMA National Risk Index score for Union County?
According to the FEMA National Risk Index, Union County, Ohio has an overall risk score of 32.7 out of 100 (Very Low). The county's social vulnerability rating is Very Low and community resilience is Very High. The Expected Annual Loss (EAL) score is Relatively Low, representing $19.0M in annualized losses.
Which natural hazard poses the greatest risk to Union County?
FEMA's NRI data points to Union County as of the latest release is Ice Storm (risk rating: Relatively Moderate). Other significant hazards include Hail (Relatively Low) and Winter Weather (Relatively Low). FEMA's modeled event frequency puts ice storm here at roughly once every 1 years, drawn from 47 historical events on record.
