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

What does Harrison County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 260 paid claims, totaling $5.6M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $21.4K 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. Harrison County's 28 federal records stand 34% above the Texas county mean of 20.9. 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 77.7/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $28.7M in annualized losses). Social vulnerability reads Relatively High and community resilience Relatively Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Ice Storm stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 1.3 times per year here, based on 90 historical events on record.

How often does each hazard strike Harrison 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 |
|---|---|---|
| Ice Storm | Very High | an average of 1.3 times per year |
| Tornado | Relatively High | roughly once every 1 years |
| Heat Wave | Relatively Moderate | 20 modeled event-days per year |
| Hail | Relatively Moderate | an average of 5.5 times per year |
| Cold Wave | Relatively High | roughly once every 1 years |
| Wildfire | Relatively Low | roughly once every 844 years |
| Winter Weather | Relatively Moderate | an average of 3.1 times per year |
| Hurricane | Relatively Low | roughly once every 22 years |
| Strong Wind | Relatively Moderate | an average of 6.3 times per year |
| Drought | Relatively Moderate | 25 modeled event-days per year |
| Lightning | Relatively Moderate | an average of 62 times per year |
| Riverine Flooding | Relatively Low | an average of 1.6 times per year |
| Earthquake | Very Low | roughly once every 808 years |
| Landslide | Very Low | roughly once every 5 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Harrison County's federal record, 25% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.
One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.
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: Ice Storm
Ice storms load power lines and tree limbs with accumulating freezing rain until they fail. The characteristic cost is infrastructure and multi-day power loss across a wide area rather than structural damage to buildings, which is why their consequences often outlast the weather that caused them.
Worth noting for Harrison County: the model and the federal record do NOT point at the same hazard. Ice Storm carries the highest modeled rating (Very High), while the county's declaration history is led by Hurricane. 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.
