The verdict
Two federal records point in the busier direction for Nemaha County. Its 25 FEMA declarations are 49% above the Nebraska county mean and exceed the count for 71% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 13%, based on modeled expected annual loss, social vulnerability, and community resilience.

FEMA National Risk Index composite score vs. the Nebraska county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Nemaha County is led by Riverine Flooding (about $1.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Drought carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Nemaha County's hazard record show?
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 25 entries for Nemaha County, including 22 Major Disaster records, 49% above the Nebraska county mean. Across the 52-year span, that works out to 0.5 declarations a year. Severe Storm leads the file with 13 entries. Declaration type records the federal action taken, not every assistance program approved.
FEMA National Risk Index
FEMA's National Risk Index places this county in the low end of the national distribution, composite score 13.4/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $5.1M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively Moderate) and community resilience (Relatively High). 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 11 modeled event-days per year here, based on 294 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 49 claims and $453.7K 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. Nemaha County's 25 federal records stand 49% above the Nebraska county mean of 16.8. 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 Nemaha 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 | 11 modeled event-days per year |
| Landslide | Relatively Low | roughly once every 11 years |
| Wildfire | Relatively Low | roughly once every 574 years |
| Hail | Relatively Low | an average of 7.2 times per year |
| Heat Wave | Relatively Low | 8.4 modeled event-days per year |
| Tornado | Relatively Low | roughly once every 3 years |
| Ice Storm | Relatively Low | roughly once every 1 years |
| Cold Wave | Relatively Low | an average of 3.4 times per year |
| Strong Wind | Relatively Low | an average of 4.4 times per year |
| Winter Weather | Very Low | an average of 12 times per year |
| Lightning | Very Low | an average of 48 times per year |
| Riverine Flooding | Very Low | an average of 2.2 times per year |
| Earthquake | Very Low | roughly once every 1,328 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Nemaha County's record, 52% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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 Nemaha 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 Severe Storm. 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.

What this means for Nemaha County
Nemaha County, NE has 25 federal declaration records, 49% more than the Nebraska county mean of 17; its history sits in PlainHazard's high activity band.
- Within this above-state-average declaration file, major disaster leads with 22 of 25 records; the category describes past federal action, not the next likely hazard. Nebraska overview
- The state benchmark and national rank point the same way: this count tops the Nebraska mean and the totals for 71% of 3,266 U.S. counties. Most-disaster rankings
- A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. Disaster-data guide
An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
