Dyer County's FEMA Risk Index score
What does Dyer County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 297 paid claims, totaling $7.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $24.6K 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. Dyer County's 24 federal records stand 12% 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 86.6/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Low (roughly $47.3M in annualized losses). Social vulnerability reads Relatively High and community resilience Relatively Moderate, both critical modifiers of realized harm here. Among the 18 modeled hazards, Earthquake carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 62 years here.

How often does each hazard strike Dyer 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 |
|---|---|---|
| Earthquake | Relatively Moderate | roughly once every 62 years |
| Tornado | Relatively Moderate | roughly once every 2 years |
| Ice Storm | Relatively High | an average of 1.3 times per year |
| Heat Wave | Relatively Moderate | 17 modeled event-days per year |
| Winter Weather | Relatively Moderate | an average of 7.2 times per year |
| Cold Wave | Relatively Moderate | an average of 2.6 times per year |
| Drought | Relatively Moderate | 13 modeled event-days per year |
| Lightning | Relatively Moderate | an average of 58 times per year |
| Strong Wind | Relatively Moderate | an average of 2.1 times per year |
| Landslide | Relatively Low | roughly once every 1 years |
| Hurricane | Very Low | roughly once every 47 years |
| Riverine Flooding | Relatively Low | roughly once every 1 years |
| Hail | Very Low | an average of 3.1 times per year |
| Wildfire | Very Low | roughly once every 9,526 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Dyer County's record, 42% 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: Earthquake
Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.
Worth noting for Dyer County: the model and the federal record do NOT point at the same hazard. Earthquake 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.
