What does St. Croix Island's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 1,873 claims and $35.4M 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 $18.9K. 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. St. Croix Island's 29 federal records stand 4% above the U.S. Virgin Islands county mean of 28.0. 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.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 29 entries for St. Croix Island, including 18 Major Disaster records, 4% above the U.S. Virgin Islands county mean. Across the 51-year span, that works out to 0.6 declarations a year. Hurricane leads the file with 17 entries. Declaration type records the federal action taken, not every assistance program approved.
FEMA National Risk Index
Even the county's top-rated hazard, Coastal Flooding, only reaches on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 4 years here.

How often does each hazard strike St. Croix Island?
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. These modeled frequencies are not forecasts.
| Hazard | NRI Risk Rating | Recurrence |
|---|---|---|
| Coastal Flooding | roughly once every 4 years | |
| Earthquake | roughly once every 15 years | |
| Hail | roughly once every 602 years | |
| Hurricane | roughly once every 4 years | |
| Riverine Flooding | an average of 1.4 times per year | |
| Strong Wind | roughly once every 622 years | |
| Tornado | roughly once every 602 years | |
| Tsunami | roughly once every 24 years | |
| Volcanic Activity | roughly once every 99 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on St. Croix Island's federal record, 59% 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: Coastal Flooding
Coastal Flooding is modeled separately from riverine flooding because its driver is different: surge, tide and wave action rather than a watershed draining. It is also the hazard whose baseline is moving, since the same storm rides on a higher starting sea level than it used to.
For St. Croix Island the two measures on this page point the same way: Coastal Flooding is the county's highest-rated modeled hazard, and Hurricane 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.
