Greenville County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Greenville County is led by Riverine Flooding (about $104.5M Expected Annual Loss, Historical Loss Ratio Relatively High), 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 Greenville County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 857 claims and $14.7M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $17.2K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
The declaration register points in the busier direction. Greenville County's 26 federal records stand 2% above the South Carolina county mean of 25.6. 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 94.0/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $169.0M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively Moderate, 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 1.8 times per year here, based on 124 historical events on record.

How often does each hazard strike Greenville 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 1.8 times per year |
| Lightning | Very High | an average of 56 times per year |
| Tornado | Relatively High | roughly once every 2 years |
| Riverine Flooding | Relatively High | an average of 2.8 times per year |
| Cold Wave | Relatively High | roughly once every 3 years |
| Earthquake | Relatively Moderate | roughly once every 394 years |
| Hail | Relatively Moderate | an average of 4.8 times per year |
| Strong Wind | Relatively High | an average of 2.6 times per year |
| Heat Wave | Relatively Moderate | 1.1 modeled event-days per year |
| Hurricane | Relatively Moderate | roughly once every 23 years |
| Landslide | Relatively Low | roughly once every 1 years |
| Winter Weather | Relatively Low | an average of 4.8 times per year |
| Wildfire | Very Low | roughly once every 3,467 years |
| Drought | Relatively Low | 42 modeled event-days per year |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Greenville County's federal record, 42% 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 Greenville 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.
