Warren County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Warren County is led by Riverine Flooding (about $6.5M Expected Annual Loss, Historical Loss Ratio Relatively High), while Tornado carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Warren County's hazard record show?
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 63.5/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $18.4M in annualized losses), and a Relatively High social-vulnerability profile combined with Relatively Low community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Tornado carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 3 years here, based on 18 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 28 claims and $311.3K 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.
The declaration register points in the busier direction. Warren County's 22 federal records stand 3% above the Tennessee county mean of 21.4. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

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 |
|---|---|---|
| Tornado | Relatively Moderate | roughly once every 3 years |
| Drought | Relatively Moderate | 19 modeled event-days per year |
| Earthquake | Relatively Low | roughly once every 305 years |
| Cold Wave | Relatively Moderate | an average of 1.2 times per year |
| Winter Weather | Relatively Moderate | an average of 6.6 times per year |
| Strong Wind | Relatively Moderate | an average of 5.8 times per year |
| Lightning | Relatively Moderate | an average of 60 times per year |
| Riverine Flooding | Relatively Low | roughly once every 1 years |
| Hail | Relatively Low | an average of 3.7 times per year |
| Hurricane | Very Low | roughly once every 35 years |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Landslide | Very Low | roughly once every 2 years |
| Wildfire | Very Low | roughly once every 1,984 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Warren County's record, 45% 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: Tornado
Tornado exposure is the most spatially concentrated in the model: total destruction along a narrow corridor with intact property either side. County-level averages therefore understate severity badly for anyone actually in the path, and overstate it for everyone else.
For Warren County the two measures on this page point the same way: Tornado is the county's highest-rated modeled hazard (Relatively Moderate), and Severe Storm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
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.
