The verdict

Washington County has a nationally busy FEMA history: 16 declarations, more than 27% of counties in this registry. But the state comparison tempers that reading: the total is 25% below the Tennessee county mean. FEMA's separate National Risk Index places the county in the riskiest 39%; 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 Riverine Flooding (about $14.1M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Landslide carries the highest National Risk Index rating (Relatively Moderate). 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: 151 paid claims, totaling $6.0M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $40.0K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Tennessee county averages 21.4 federal declaration records, while Washington County has 16. The gap is 25% 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, 61.2/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $22.6M in annualized losses), and a Relatively Low social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Landslide 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.

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.

Hazard NRI Risk Rating Recurrence
Landslide Relatively Moderate roughly once every 1 years
Strong Wind Relatively High an average of 3.2 times per year
Lightning Relatively High an average of 51 times per year
Earthquake Relatively Low roughly once every 409 years
Riverine Flooding Relatively Low an average of 1.1 times per year
Ice Storm Relatively Moderate roughly once every 6 years
Hurricane Very Low roughly once every 61 years
Cold Wave Relatively Low roughly once every 1 years
Tornado Relatively Low roughly once every 16 years
Drought Relatively Low 17 modeled event-days per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Washington County's record, 31% 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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Washington County: the model and the federal record do NOT point at the same hazard. Landslide 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.

Data-matched county comparisons

Washington County's closest FEMA peer: Jasper County, TX

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.
