Outage risk in Wisconsin

Wisconsin's outage risk is driven by severe winter weather and summer storms rather than hurricanes: heavy lake-effect snow and ice storms off Lake Michigan create extended outages around Green Bay and the Fox Valley, while Milwaukee and Madison face summer derecho and severe-thunderstorm wind events plus occasional tornado-corridor risk typical of the upper Midwest.
