The verdict

Washington 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 8%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Washington County is led by Heat Wave (about $47.2M Expected Annual Loss, Historical Loss Ratio Very High), 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 Washington County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 435 paid claims, totaling $13.7M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $31.4K 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 Washington 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 92.3/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $129.6M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively Low, both critical modifiers of realized harm here. 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 1.9 times per year here, based on 129 historical events on record.

How often does each hazard strike Washington 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.

Ice Storm Very High an average of 1.9 times per year
Heat Wave Relatively High 9.4 modeled event-days per year
Winter Weather Very High an average of 11 times per year
Tornado Relatively High roughly once every 1 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Washington County's record, 40% 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 Washington 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 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.

Data-matched county comparisons

Washington County's closest FEMA peer: Benton County, WA

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Washington County. Record similarity, not a safety rating.

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.
