What does Monroe County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 97 paid claims, totaling $1.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $13.6K 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. Monroe County's 15 federal records stand 22% 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 National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 78.8/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $30.5M in annualized losses). Social vulnerability reads Relatively High and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Cold Wave stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 7.2 times per year here, based on 136 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 15 entries for Monroe County, including 12 Major Disaster records, 22% above the Wisconsin county mean. Across the 44-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.

How often does each hazard strike Monroe 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
Cold Wave Relatively High an average of 7.2 times per year
Landslide Relatively Moderate roughly once every 2 years
Hail Relatively Moderate an average of 3.3 times per year
Strong Wind Relatively Moderate an average of 3 times per year
Riverine Flooding Relatively Moderate roughly once every 1 years
Tornado Relatively Moderate roughly once every 3 years
Heat Wave Relatively Low 3.5 modeled event-days per year
Winter Weather Relatively Low an average of 16 times per year
Lightning Relatively Low an average of 35 times per year
Ice Storm Relatively Low roughly once every 8 years
Wildfire Very Low roughly once every 9,085 years
Drought Very Low 4.5 modeled event-days per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Monroe County's record, 47% 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: Cold Wave

Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.

Worth noting for Monroe County: the model and the federal record do NOT point at the same hazard. Cold Wave carries the highest modeled rating (Relatively High), 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.

Data-matched county comparisons

Monroe County's closest FEMA peer: Vermilion County, IL

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Monroe County. Record similarity, not a safety rating.

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.
