Weber County's FEMA Risk Index score
What does Weber County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 88 paid claims, totaling $320.9K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $3.6K 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. Weber County's 11 federal records stand 30% above the Utah county mean of 8.5. 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 87.0/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $103.9M in annualized losses). Social vulnerability reads Very Low and community resilience Very High, both critical modifiers of realized harm here. Among the 18 modeled hazards, Earthquake carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 67 years here.

How often does each hazard strike Weber 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 |
|---|---|---|
| Earthquake | Relatively Moderate | roughly once every 67 years |
| Lightning | Relatively High | an average of 33 times per year |
| Wildfire | Relatively Moderate | roughly once every 315 years |
| Avalanche | Relatively High | roughly once every 2 years |
| Winter Weather | Relatively High | an average of 33 times per year |
| Heat Wave | Relatively Moderate | 1.2 modeled event-days per year |
| Strong Wind | Relatively Moderate | an average of 1.1 times per year |
| Riverine Flooding | Relatively Low | roughly once every 2 years |
| Landslide | Very Low | roughly once every 2 years |
| Cold Wave | Relatively Low | roughly once every 6 years |
| Drought | Relatively Low | 48 modeled event-days per year |
| Ice Storm | Relatively Low | roughly once every 67 years |
| Tornado | Relatively Low | roughly once every 21 years |
| Hail | Very Low | roughly once every 3 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Weber County's record, 36% 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: Earthquake
Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.
Worth noting for Weber County: the model and the federal record do NOT point at the same hazard. Earthquake 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.

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.
