Risk Overview

About Natural Disaster Risk in Chippewa County, Wisconsin

Chippewa's risk sits above average

Chippewa County scores 67.33 on the national composite risk scale, rating it as Relatively Low but above Wisconsin's state average of 59.08. This means Chippewa faces somewhat elevated natural disaster exposure compared to typical Wisconsin counties, though it remains below the highest-risk counties nationally.

Middle of the pack in Wisconsin

Among Wisconsin's 72 counties, Chippewa ranks in the middle range for overall natural disaster risk. The county's 67.33 score places it well above the lowest-risk Wisconsin counties but comfortably below the state's most vulnerable areas.

Riskier than Clark, safer than Dodge

Compared to nearby counties, Chippewa (67.33) sits between Clark County (68.45) and Dodge County (69.91) in risk exposure. All three are relatively similar in vulnerability, though each faces distinct hazard patterns across flooding, tornadoes, and other threats.

Tornadoes and flooding are primary concerns

Chippewa's tornado risk scores 70.90 and flood risk reaches 71.02, making these the county's dominant natural hazards. Wildfire risk remains low at 20.04, while earthquake (10.27) and hurricane (0.00) threats are minimal for this north-central Wisconsin location.

Flood and storm coverage matter most

With tornado and flood risks both exceeding 70, Chippewa residents should prioritize comprehensive homeowners insurance with windstorm and flood endorsements. Review your coverage now—standard homeowners policies often exclude flood damage, leaving gaps that separate insurance during a disaster.

Risk Verdict

Chippewa County's FEMA risk score places it at the 67th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Flood risk is Chippewa County's dominant natural hazard, ranked at the 71th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 71th percentile nationally. Additional tracked hazards include wildfire (20th percentile), earthquake (10th percentile), hurricane (0th percentile).

Preparedness Context

At the 71th percentile nationally for flood risk, Chippewa County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Alongside flooding, tornado exposure at the 71th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A tested family preparedness plan specific to Chippewa County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.

Regional Context

The Wisconsin county average is 8.3 composite points below Chippewa County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
