The verdict
Dunn County has a nationally busy FEMA history: 18 declarations, more than 37% of counties in this registry. But the state comparison tempers that reading: the total is 30% below the North Dakota county mean. FEMA's separate National Risk Index places the county safer than 11%; that score models loss and vulnerability rather than counting declarations.

Dunn County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Dunn County is led by Riverine Flooding (about $1.3M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Dunn County's hazard record show?
FEMA National Risk Index
FEMA's National Risk Index places this county in the low end of the national distribution, composite score 10.8/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.8M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively Moderate) and community resilience (Very Low). Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 2.2 times per year here, based on 85 historical events on record.
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 North Dakota county averages 25.9 federal declaration records, while Dunn County has 18. The gap is 30% 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 Dunn 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 |
|---|---|---|
| Hail | Relatively Moderate | an average of 2.2 times per year |
| Wildfire | Relatively Low | roughly once every 1,149 years |
| Winter Weather | Relatively Moderate | an average of 17 times per year |
| Ice Storm | Relatively Moderate | roughly once every 2 years |
| Cold Wave | Relatively Low | an average of 14 times per year |
| Landslide | Very Low | roughly once every 1 years |
| Drought | Very Low | 28 modeled event-days per year |
| Tornado | Very Low | roughly once every 2 years |
| Strong Wind | Relatively Low | an average of 1.3 times per year |
| Lightning | Very Low | an average of 30 times per year |
| Riverine Flooding | Very Low | roughly once every 2 years |
| Heat Wave | Very Low | 1.1 modeled event-days per year |
| Earthquake | Very Low | roughly once every 12,821 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Dunn County's record, 33% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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: Hail
Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.
For Dunn County the two measures on this page point the same way: Hail is the county's highest-rated modeled hazard (Relatively Moderate), and Severe Storm 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 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.
