Risk Overview

About Natural Disaster Risk in Monroe County, Wisconsin

Monroe sits above average national risk

Monroe County's composite risk score of 78.85 exceeds the national average, though its "Relatively Low" rating reflects Wisconsin's overall risk profile. The county faces meaningful exposure to flooding and tornadoes that warrant attention from property owners.

Mid-range risk within Wisconsin

Monroe County's score of 78.85 ranks it in the upper-middle tier of Wisconsin counties, well above the state average of 59.08. This positioning reflects the county's placement in a region with elevated severe weather activity.

Elevated risk compared to neighbors

Monroe County's score of 78.85 outpaces nearby Oneida County (62.53) but trails Outagamie County (79.68). The variation across this region shows how local geography and weather patterns create distinct risk profiles even among adjacent communities.

Flooding and tornadoes dominate threats

Flood risk scores 78.44 and tornado risk reaches 76.34 in Monroe County, making these the primary natural disaster concerns for residents. Earthquake risk of 17.59 presents a secondary but non-zero concern, unusual for Wisconsin.

Flood and wind coverage recommended

Monroe County residents should obtain standalone flood insurance, as standard homeowners policies exclude flood damage—critical given the county's 78.44 flood score. Wind and hail coverage should also be verified, given tornado risk of 76.34.
