What does Northern Mariana Islands's hazard record show?
Declaration frequency
The state comparison is the clearest context for Northern Mariana Islands's moderate federal record. Its 6 declarations sit 67% below the Northern Mariana Islands county mean, with 2 Major Disaster entries among them. 4 records concern Tropical Storm, the file's most frequent incident type. Spread across 6 years, the registry rate is 1.0 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.
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 Northern Mariana Islands county averages 18.2 federal declaration records, while Northern Mariana Islands has 6. The gap is 67% 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.

What Tropical Storm declarations mean here
Tropical Storm is the most frequent declaration type on Northern Mariana Islands's federal record, 67% 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.

Data Sources & Methodology
Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.
Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.
This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.

- Emergency is the largest group (4 of 6) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Northern Mariana Islands overview
- Nationally the county exceeds 3% of recorded county totals, but its own Northern Mariana Islands benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
- With no NFIP county row, the declaration register and modeled NRI remain distinct evidence rather than substitutes for a claims history. Disaster-data guide
A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
