The verdict
Two federal records point in the busier direction for Morton County. Its 27 FEMA declarations are 4% above the North Dakota county mean and exceed the count for 78% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 50%, based on modeled expected annual loss, social vulnerability, and community resilience.

Morton County's FEMA Risk Index score
FEMA National Risk Index composite score vs. the North Dakota county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Morton County is led by Riverine Flooding (about $7.9M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Hail carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Morton County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 216 paid claims, totaling $2.8M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $13.1K 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. Morton County's 27 federal records stand 4% above the North Dakota county mean of 25.9. 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
FEMA's data shows an elevated National Risk Index composite of 49.6/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Relatively Low (roughly $25.6M in annualized losses). Social vulnerability (Very Low) and community resilience (Very High) both factor into how that raw exposure plays out on the ground. Of the 18 hazards FEMA models, Hail stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 2.6 times per year here, based on 101 historical events on record.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 27 entries for Morton County, including 24 Major Disaster records, 4% above the North Dakota county mean. Across the 59-year span, that works out to 0.5 declarations a year. Flood leads the file with 16 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Morton 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 High | an average of 2.6 times per year |
| Winter Weather | Relatively High | an average of 19 times per year |
| Ice Storm | Relatively High | roughly once every 1 years |
| Cold Wave | Relatively Moderate | an average of 14 times per year |
| Wildfire | Relatively Low | roughly once every 1,731 years |
| Tornado | Relatively Low | roughly once every 2 years |
| Strong Wind | Relatively Low | an average of 1.7 times per year |
| Riverine Flooding | Relatively Low | roughly once every 1 years |
| Landslide | Very Low | roughly once every 2 years |
| Heat Wave | Very Low | 2 modeled event-days per year |
| Lightning | Very Low | an average of 31 times per year |
| Drought | Very Low | 18 modeled event-days per year |
| Earthquake | Very Low | roughly once every 9,346 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Morton County's record, 59% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.
Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.
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.
Worth noting for Morton County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
