Outage risk in Iowa

Iowa's outage risk is driven by severe spring and summer thunderstorm activity across the state, including derecho-scale straight-line wind events like the 2020 Cedar Rapids derecho, plus tornado-corridor risk through central Iowa around Des Moines, and winter ice storms statewide; the western Sioux City area along the Missouri River adds periodic river flooding and more exposure to fast-moving Plains storm systems than the state's eastern half.
