Risk Overview

About Natural Disaster Risk in Adams County, Wisconsin

Adams County's moderate risk profile

Adams County scores 70.90 on the national composite risk scale, placing it in the Relatively Low category—well above Wisconsin's state average of 59.08. While this county faces more natural disaster risk than most Wisconsinites, it remains below the national median for composite risk exposure.

Higher than average across Wisconsin

Adams County ranks among the state's higher-risk counties despite its "Relatively Low" designation, reflecting Wisconsin's overall favorable position on natural disaster exposure. The county's 70.90 score significantly exceeds Wisconsin's 59.08 average, placing it in the upper portion of the state's risk distribution.

Riskier than most nearby counties

Adams County's risk profile stands notably higher than neighboring Burnett County (49.33) and Calumet County (30.18), but slightly below Barron County (68.64). Among its peers, Adams faces more consistent exposure across multiple hazard types rather than concentrated risk in a single category.

Tornado and flood threats lead risks

Tornado risk dominates Adams County at 73.44, followed closely by flood risk at 72.46—both substantially higher than the county's other hazards. Wildfire risk, while present at 53.12, poses a secondary threat compared to these two weather-related hazards that affect the broadest areas of the county.

Secure coverage against storms now

Adams County residents should prioritize comprehensive homeowners insurance that explicitly covers tornado and flood damage, as these represent the county's dominant risks. Standard homeowners policies typically exclude flood coverage, so separate flood insurance through the National Flood Insurance Program should be a critical consideration.

Hazard Breakdown

Preparedness Context

Adams County ranks at the 73th percentile nationally for tornado exposure.

Flood is the second hazard driver for Adams County at the 72th percentile nationally, meaning households should maintain awareness of both severe-weather and flood-specific warning systems. Adams County county emergency management typically publishes annual severe-weather preparedness guides tailored to local tornado patterns; households benefit from reviewing these before storm season begins each spring.

Regional Context

Compared to other Wisconsin counties, Adams County runs 11.8 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.
