Cheyenne County's FEMA Risk Index score
What does Cheyenne County's hazard record show?
FEMA National Risk Index
This county sits at the very bottom of FEMA's National Risk Index nationally, a composite score of 3.0/100 (rated Very Low). Projected losses are minimal, Expected Annual Loss reads Very Low (roughly $3.0M in annualized losses), and the county's exposure is shaped by a Very Low social-vulnerability profile and Very Low community resilience. 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 84 modeled event-days per year here, based on 2,128 historical events on record.
Reading the federal records together
No paid-claim row for this county appears in the NFIP county table used by PlainHazard. That absence is not evidence that flooding never occurred: the register observes claims under federal flood-insurance policies, not uninsured losses, emergency reports, or every flood outside the program. The FEMA declaration history below is therefore the available federal-action record on this page.
Start with the state benchmark: a Colorado county averages 10.2 federal declaration records, while Cheyenne County has 9. The gap is 12% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Cheyenne 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 | 84 modeled event-days per year |
| Hail | Relatively Low | an average of 6.2 times per year |
| Cold Wave | Relatively Low | an average of 5.2 times per year |
| Wildfire | Very Low | roughly once every 2,188 years |
| Winter Weather | Relatively Low | an average of 12 times per year |
| Tornado | Very Low | an average of 1.7 times per year |
| Strong Wind | Very Low | an average of 2.5 times per year |
| Earthquake | Very Low | roughly once every 2,364 years |
| Lightning | Very Low | an average of 47 times per year |
| Riverine Flooding | Very Low | roughly once every 1 years |
| Ice Storm | Very Low | roughly once every 45 years |
| Heat Wave | Very Low | 0.2 modeled event-days per year |
| Landslide | Very Low | roughly once every 6 years |

What Biological declarations mean here
Biological is the most frequent declaration type on Cheyenne County's record, 22% of its declarations. In practice this category is dominated by the COVID-19 declarations of 2020, which were issued across every US state and territory rather than in response to any local hazard event.
This has a direct consequence for how Cheyenne County's number should be read. Because those declarations reached essentially every county in the country, they raise every county's total by a similar amount and tell you nothing about local hazard exposure. A county whose record is led by Biological declarations is, in most cases, a county with a genuinely quiet weather-hazard history, the pandemic records are simply the largest thing in an otherwise short list.
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 Cheyenne 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 Biological. 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.

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.
Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.
