Sibley County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Sibley County is led by Riverine Flooding (about $6.1M Expected Annual Loss, Historical Loss Ratio Relatively High), while Strong Wind carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Sibley County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 23.0/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $13.5M in annualized losses), tempered or compounded by a Very Low social-vulnerability score and Very High community-resilience score. Among the 18 modeled hazards, Strong Wind carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 4.2 times per year here, based on 160 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 12 claims and $66.2K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.
The declaration register points in the busier direction. Sibley 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.

How often does each hazard strike Sibley 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 |
|---|---|---|
| Strong Wind | Relatively Moderate | an average of 4.2 times per year |
| Hail | Relatively Low | an average of 5.8 times per year |
| Drought | Relatively Low | 7.4 modeled event-days per year |
| Cold Wave | Relatively Low | an average of 11 times per year |
| Landslide | Very Low | roughly once every 14 years |
| Tornado | Relatively Low | roughly once every 2 years |
| Winter Weather | Relatively Low | an average of 19 times per year |
| Heat Wave | Very Low | 5.1 modeled event-days per year |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Riverine Flooding | Very Low | roughly once every 1 years |
| Wildfire | Very Low | roughly once every 9,273 years |
| Lightning | Very Low | an average of 37 times per year |
| Earthquake | Very Low | roughly once every 3,257 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Sibley County's record, 52% 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: Strong Wind
Strong Wind covers damaging non-thunderstorm, non-tornadic wind, the kind produced by steep pressure gradients and downslope events. It is a broad, frequent, low-drama hazard: roofs, signage, power lines and high-profile vehicles, spread across a wide area rather than concentrated on a path.
Worth noting for Sibley County: the model and the federal record do NOT point at the same hazard. Strong Wind 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.
