The verdict
Union County has a nationally busy FEMA history: 20 declarations, more than 46% of counties in this registry. But the state comparison tempers that reading: the total is 17% below the Arkansas county mean. FEMA's separate National Risk Index places the county in the riskiest 46%; 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 $4.9M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Ice Storm carries the highest National Risk Index rating (Very High). 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: 137 paid claims, totaling $2.1M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $15.1K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a Arkansas county averages 24.2 federal declaration records, while Union County has 20. The gap is 17% 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 carries a high composite score on FEMA's National Risk Index, 53.9/100, rated Relatively Low. Its Expected Annual Loss rating is Very Low (roughly $12.6M in annualized losses), and a Very High social-vulnerability profile combined with Relatively Moderate community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Ice Storm stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 1.3 times per year here, based on 85 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 | Very High | an average of 1.3 times per year |
| Heat Wave | Relatively Moderate | 19 modeled event-days per year |
| Strong Wind | Relatively Moderate | an average of 3.9 times per year |
| Earthquake | Relatively Low | roughly once every 406 years |
| Tornado | Relatively Moderate | roughly once every 1 years |
| Lightning | Relatively Moderate | an average of 65 times per year |
| Hurricane | Relatively Low | roughly once every 25 years |
| Hail | Relatively Low | an average of 3.9 times per year |
| Riverine Flooding | Relatively Low | an average of 1.3 times per year |

What Flood declarations mean here
Flood is the most frequent declaration type on Union County's record, 30% 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: 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 (Very 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.

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.
