Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Río Grande Municipio is led by Hurricane (about $23.6M Expected Annual Loss, Historical Loss Ratio Relatively High), while Coastal Flooding carries the highest National Risk Index rating (null). EAL and risk score use different inputs; they need not agree.

What does Río Grande Municipio's hazard record show?
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 5 years here.
Reading the federal records together
No paid-claim row for this county appears in the NFIP county table used by PlainHazard. That absence is not evidence that flooding never occurred: the register observes claims under federal flood-insurance policies, not uninsured losses, emergency reports, or every flood outside the program. The FEMA declaration history below is therefore the available federal-action record on this page.
Start with the state benchmark: a Puerto Rico county averages 27.1 federal declaration records, while Río Grande Municipio has 26. The gap is 4% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Río Grande Municipio?
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 |
|---|---|---|
| Coastal Flooding | roughly once every 5 years | |
| Drought | 1.5 modeled event-days per year | |
| Earthquake | roughly once every 22 years | |
| Hail | roughly once every 38 years | |
| Hurricane | roughly once every 4 years | |
| Riverine Flooding | roughly once every 1 years | |
| Landslide | an average of 4.6 times per year | |
| Lightning | an average of 68 times per year | |
| Strong Wind | roughly once every 201 years | |
| Tornado | roughly once every 636 years | |
| Tsunami | roughly once every 18 years | |
| Volcanic Activity | roughly once every 99 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Río Grande Municipio's federal record, 50% 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 Río Grande Municipio 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.
