The verdict

Two federal records point in the busier direction for Norman County. Its 32 FEMA declarations are 81% above the Minnesota county mean and exceed the count for 89% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 14%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Norman County is led by Riverine Flooding (about $2.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Drought carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Norman County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 247 paid claims, totaling $2.5M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $9.9K 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. Norman County's 32 federal records stand 81% above the Minnesota county mean of 17.7. 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 National Risk Index places this county in the low end of the national distribution, composite score 14.4/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $5.5M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively Moderate) and community resilience (Relatively Moderate). Among the 18 modeled hazards, Drought carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at 6.4 modeled event-days per year here, based on 189 historical events on record.

How often does each hazard strike Norman 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
Drought Relatively Moderate 6.4 modeled event-days per year
Hail Relatively Low an average of 4 times per year
Winter Weather Relatively Moderate an average of 24 times per year
Cold Wave Relatively Low an average of 20 times per year
Ice Storm Relatively Low roughly once every 4 years
Wildfire Very Low roughly once every 437 years
Strong Wind Relatively Low an average of 2.4 times per year
Landslide Very Low roughly once every 12 years
Tornado Very Low roughly once every 2 years
Riverine Flooding Very Low roughly once every 1 years

What Flood declarations mean here

Flood is the most frequent declaration type on Norman County's record, 56% 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: Drought

Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.

Worth noting for Norman County: the model and the federal record do NOT point at the same hazard. Drought carries the highest modeled rating (Relatively Moderate), 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.

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Norman County. 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.

What is the FEMA National Risk Index score for Norman County?
According to the FEMA National Risk Index, Norman County, Minnesota has an overall risk score of 14.4 out of 100 (Very Low). On social vulnerability the county rates Relatively Moderate; on community resilience, Relatively Moderate. The Expected Annual Loss (EAL) score is Very Low, representing $5.5M in annualized losses.
Which natural hazard poses the greatest risk to Norman County?
FEMA's NRI data points to Norman County as of the latest release is Drought (risk rating: Relatively Moderate). Other significant hazards include Hail (Relatively Low) and Winter Weather (Relatively Moderate). FEMA's modeled event frequency puts drought here at 6.4 modeled event-days per year, drawn from 189 historical events on record. FEMA derives these ratings from historical event frequency, the assets exposed, and the community's vulnerability profile.
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.
