What does Patillas Municipio's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 128 paid claims, totaling $604.0K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $4.7K 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. Patillas Municipio's 29 federal records stand 7% above the Puerto Rico county mean of 27.1. 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

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 Patillas 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 4 years
Drought 7.6 modeled event-days per year
Earthquake roughly once every 28 years
Hail roughly once every 39 years
Hurricane roughly once every 5 years
Riverine Flooding roughly once every 2 years
Landslide an average of 7.7 times per year
Lightning an average of 70 times per year
Strong Wind roughly once every 201 years
Tornado roughly once every 574 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 Patillas Municipio's federal record, 48% 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 Patillas 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.

Data-matched county comparisons

Patillas Municipio's closest FEMA peer: Etowah County, AL

Comparisons use published FEMA declaration fields for Patillas Municipio. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.
