FEMA National Risk Index composite score vs. the Illinois county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Ogle County is led by Riverine Flooding (about $21.1M 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 Ogle County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 307 paid claims, totaling $3.5M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $11.5K 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. Ogle County's 14 federal records stand 9% above the Illinois county mean of 12.9. 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
This county carries a high composite score on FEMA's National Risk Index, 71.1/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $36.1M in annualized losses), and a Very Low social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. 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 4.1 times per year here, based on 157 historical events on record.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 14 entries for Ogle County, including 8 Major Disaster records, 9% above the Illinois county mean. Across the 47-year span, that works out to 0.3 declarations a year. Snowstorm leads the file with 5 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Ogle 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 4.1 times per year |
| Cold Wave | Relatively Moderate | an average of 5.7 times per year |
| Tornado | Relatively Moderate | roughly once every 1 years |
| Riverine Flooding | Relatively Moderate | an average of 1.2 times per year |
| Strong Wind | Relatively Moderate | an average of 6.2 times per year |
| Drought | Relatively Moderate | 11 modeled event-days per year |
| Earthquake | Relatively Low | roughly once every 803 years |
| Ice Storm | Relatively Low | roughly once every 1 years |
| Landslide | Very Low | roughly once every 7 years |
| Heat Wave | Relatively Low | 3.6 modeled event-days per year |
| Lightning | Relatively Low | an average of 41 times per year |
| Winter Weather | Very Low | an average of 15 times per year |
| Hurricane | Very Low | roughly once every 174 years |
| Wildfire | Very Low | roughly once every 14,460 years |

What Snowstorm declarations mean here
Snowstorm is the most frequent declaration type on Ogle County's record, 36% of its declarations. Snow-related declarations work on a narrower basis than most other hazards: they are generally issued to reimburse the cost of snow removal and emergency protective measures, rather than to repair destroyed property.
The qualifying test is unusual too. FEMA assesses snowfall against record levels for the affected area, so the same storm total can qualify in a county where it is historically extreme and not qualify a few hundred miles north where it is an ordinary winter. A low snowstorm declaration count is therefore not evidence of mild winters.
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 Ogle County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Snowstorm. 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.

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.
