Marion County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Marion County is led by Riverine Flooding (about $7.7M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Strong Wind carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Marion County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 117 paid claims, totaling $1.2M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $10.3K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
The declaration register points in the busier direction. Marion County's 25 federal records stand 17% 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.
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 58.2/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $16.4M 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, Strong Wind carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 5.2 times per year here, based on 197 historical events on record.

How often does each hazard strike Marion 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 |
|---|---|---|
| Strong Wind | Relatively Moderate | an average of 5.2 times per year |
| Tornado | Relatively Moderate | roughly once every 3 years |
| Landslide | Relatively Low | an average of 1.1 times per year |
| Cold Wave | Relatively Moderate | roughly once every 1 years |
| Earthquake | Relatively Low | roughly once every 308 years |
| Winter Weather | Relatively Moderate | an average of 5.2 times per year |
| Riverine Flooding | Relatively Low | roughly once every 1 years |
| Wildfire | Very Low | roughly once every 299 years |
| Drought | Relatively Low | 30 modeled event-days per year |
| Ice Storm | Relatively Low | roughly once every 1 years |
| Hurricane | Very Low | roughly once every 73 years |

| Heat Wave | Very Low | 1.6 modeled event-days per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Marion County's record, 36% 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: Strong Wind
Strong Wind covers damaging non-thunderstorm, non-tornadic wind, the kind produced by steep pressure gradients and downslope events. It is a broad, frequent, low-drama hazard: roofs, signage, power lines and high-profile vehicles, spread across a wide area rather than concentrated on a path.
For Marion County the two measures on this page point the same way: Strong Wind 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.
