Simpson County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Simpson County is led by Riverine Flooding (about $5.2M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Hurricane carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Simpson County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 246 paid claims, totaling $2.6M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $10.5K 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. Simpson County's 30 federal records stand 16% above the Mississippi county mean of 25.9. 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, 51.0/100, rated Relatively Low. Its Expected Annual Loss rating is Very Low (roughly $12.4M 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. Even the county's top-rated hazard, Hurricane, only reaches Relatively 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 9 years here, based on 31 historical events on record.

How often does each hazard strike Simpson 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 |
|---|---|---|
| Hurricane | Relatively Low | roughly once every 9 years |
| Hail | Relatively Moderate | an average of 4.7 times per year |
| Tornado | Relatively Moderate | roughly once every 1 years |
| Heat Wave | Relatively Low | 14 modeled event-days per year |
| Strong Wind | Relatively Moderate | an average of 3.9 times per year |
| Landslide | Relatively Low | roughly once every 2 years |
| Drought | Relatively Low | 10 modeled event-days per year |
| Ice Storm | Relatively Low | an average of 1.1 times per year |
| Lightning | Relatively Low | an average of 75 times per year |
| Riverine Flooding | Relatively Low | an average of 1 time per year |
| Wildfire | Very Low | roughly once every 771 years |
| Cold Wave | Relatively Low | roughly once every 1 years |
| Earthquake | Very Low | roughly once every 710 years |
| Winter Weather | Relatively Low | an average of 2.2 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Simpson County's record, 40% 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: Hurricane
Hurricane exposure in the model bundles the three ways a tropical system does harm, which arrive on different timescales and are insured differently: wind, storm surge on the coast, and rainfall flooding that can reach far inland well after landfall.
Worth noting for Simpson County: the model and the federal record do NOT point at the same hazard. Hurricane carries the highest modeled rating (Relatively 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.
