Chippewa County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Chippewa County is led by Riverine Flooding (about $5.2M Expected Annual Loss, Historical Loss Ratio Very High), while Winter Weather carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Chippewa County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 172 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 $14.7K 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. Chippewa County's 21 federal records stand 19% 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 data shows an elevated National Risk Index composite of 37.0/100 for this county (Very Low rating). Expected Annual Loss comes in at Very Low (roughly $10.2M in annualized losses). Social vulnerability (Relatively High) and community resilience (Very High) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Winter Weather carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 20 times per year here, based on 387 historical events on record.

How often does each hazard strike Chippewa 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 |
|---|---|---|
| Winter Weather | Relatively Moderate | an average of 20 times per year |
| Heat Wave | Relatively Low | 3.9 modeled event-days per year |
| Cold Wave | Relatively Moderate | an average of 13 times per year |
| Hail | Relatively Low | an average of 3.9 times per year |
| Drought | Relatively Low | 7.9 modeled event-days per year |
| Strong Wind | Relatively Moderate | an average of 2.7 times per year |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Riverine Flooding | Relatively Low | roughly once every 2 years |
| Tornado | Relatively Low | roughly once every 3 years |
| Landslide | Very Low | roughly once every 16 years |
| Wildfire | Very Low | roughly once every 2,028 years |
| Lightning | Very Low | an average of 35 times per year |
| Earthquake | Very Low | roughly once every 4,950 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Chippewa County's record, 48% 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: Winter Weather
Winter Weather in the model means the accumulation of snow and cold that disrupts rather than destroys: road closures, roof loads, burst pipes and lost heating. Its costs land heavily on transport and on households least able to absorb an interruption.
Worth noting for Chippewa County: the model and the federal record do NOT point at the same hazard. Winter Weather 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.
