The verdict

Warren County has a nationally busy FEMA history: 17 declarations, more than 32% of counties in this registry. But the state comparison tempers that reading: the total is 1% below the Indiana county mean. FEMA's separate National Risk Index places the county safer than 6%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Warren County is led by Riverine Flooding (about $1.9M Expected Annual Loss, Historical Loss Ratio Relatively High), while Landslide carries the highest National Risk Index rating (Very Low). EAL and risk score use different inputs; they need not agree.

What does Warren County's hazard record show?

FEMA National Risk Index

FEMA's National Risk Index places this county in the low end of the national distribution, composite score 5.8/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.1M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Very Low) and community resilience (Relatively High). Even the county's top-rated hazard, Landslide, only reaches Very Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 11 years here.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 2 claims and $2.0K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

Start with the state benchmark: a Indiana county averages 17.1 federal declaration records, while Warren County has 17. The gap is 1% 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.

How often does each hazard strike Warren 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 Very Low roughly once every 11 years
Cold Wave Relatively Low an average of 3.7 times per year
Drought Relatively Low 0.9 modeled event-days per year
Earthquake Very Low roughly once every 490 years
Winter Weather Relatively Low an average of 9.4 times per year
Hail Very Low an average of 3 times per year
Tornado Very Low roughly once every 3 years
Hurricane Very Low roughly once every 36 years
Heat Wave Very Low 4.6 modeled event-days per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Warren County's record, 29% 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 Warren County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Very Low), 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

Warren County's closest FEMA peer: Allegan County, MI

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Warren 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.
