Monona County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Monona County is led by Riverine Flooding (about $3.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Drought carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Monona County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 25.1/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $8.7M in annualized losses), tempered or compounded by a Relatively Low social-vulnerability score and Very High community-resilience score. 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 26 modeled event-days per year here, based on 994 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 30 claims and $700.7K 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. Monona County's 20 federal records stand 4% above the Iowa county mean of 19.3. 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 Monona 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 | 26 modeled event-days per year |
| Hail | Relatively Moderate | an average of 6.1 times per year |
| Landslide | Relatively Low | roughly once every 3 years |
| Wildfire | Relatively Low | roughly once every 291 years |
| Tornado | Relatively Low | roughly once every 2 years |
| Ice Storm | Relatively Low | roughly once every 1 years |
| Strong Wind | Relatively Low | an average of 4.3 times per year |
| Cold Wave | Relatively Low | an average of 6.1 times per year |
| Heat Wave | Very Low | 5.6 modeled event-days per year |
| Riverine Flooding | Very Low | roughly once every 2 years |
| Earthquake | Very Low | roughly once every 1,852 years |
| Lightning | Very Low | an average of 43 times per year |
| Winter Weather | Very Low | an average of 14 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Monona County's record, 40% 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 Monona 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.
