17 FEMA disaster declarations (1969-2020), with a FEMA National Risk Index rating of Relatively Low. Most common hazard: Severe Storm.
The verdict
Two federal records point in the busier direction for Green County. Its 17 FEMA declarations are 38% above the Wisconsin county mean and exceed the count for 32% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 46%, based on modeled expected annual loss, social vulnerability, and community resilience.
FEMA's National Risk Index and its declaration registry are separate measures. This county's registry includes Major Disaster (DR) and Emergency (EM) records; an EM authorizes a narrower set of federal assistance than a DR.

FEMA's modeled annual dollar loss for Green County is led by Riverine Flooding (about $6.8M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

FEMA's data shows an elevated National Risk Index composite of 46.4/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Relatively Low (roughly $17.8M in annualized losses). Social vulnerability (Very Low) and community resilience (Very High) both factor into how that raw exposure plays out on the ground. 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 3.6 times per year here, based on 138 historical events on record.
The FEMA register is busy by both local and national comparisons. It contains 17 entries for Green County, including 12 Major Disaster records, 38% above the Wisconsin county mean. Across the 51-year span, that works out to 0.3 declarations a year. Severe Storm leads the file with 7 entries. Declaration type records the federal action taken, not every assistance program approved.
This county has a small entry in FEMA's NFIP paid-claims table: 36 claims and $291.0K 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. Green County's 17 federal records stand 38% above the Wisconsin county mean of 12.3. 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.

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 3.6 times per year |
| Landslide | Relatively Low | roughly once every 3 years |
| Cold Wave | Relatively Moderate | an average of 5.7 times per year |
| Tornado | Relatively Moderate | roughly once every 2 years |
| Strong Wind | Relatively Moderate | an average of 4.7 times per year |
| Heat Wave | Relatively Low | 3.7 modeled event-days per year |
| Riverine Flooding | Relatively Low | an average of 1.7 times per year |
| Ice Storm | Relatively Low | roughly once every 1 years |
| Drought | Relatively Low | 7.2 modeled event-days per year |
| Wildfire | Very Low | roughly once every 5,270 years |
| Winter Weather | Relatively Low | an average of 15 times per year |
| Lightning | Relatively Low | an average of 38 times per year |
| Earthquake | Very Low | roughly once every 1,217 years |
| Hurricane | Very Low | roughly once every 135 years |

Severe Storm is the most frequent declaration type on Green County's record, 41% 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.
FEMA categorizes declarations as Major Disasters (DR), Emergencies (EM), or Fire Management Assistance (FM).

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.
For Green County the two measures on this page point the same way: Hail is the county's highest-rated modeled hazard (Relatively Moderate), and Severe Storm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
Data-matched county comparisons
Comparisons use published FEMA declaration fields plus the National Risk Index composite for Green County. Record similarity, not a safety rating.
Green County shows 17 FEMA declarations, led by Severe Storm.
Green County: 12 of 17 of its declarations are Major.
Green County: NRI composite 46.4 (Relatively Low).
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.

What this means for Green County
Green County, WI has 17 federal declaration records, 38% more than the Wisconsin county mean of 12; its history sits in PlainHazard's high activity band.
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.
PlainHazard derives this profile from FEMA's Disaster Declarations Summaries and National Risk Index data.
