LAKE GENEVA, Wis. (AP) — Three children who died when a boat capsized in Geneva Lake during a Wisconsin storm were wearing life vests, authorities said as the nation assessed damage from storms and a heat wave that marred the July Fourth holiday, leaving hundreds of thousands of utility customers without power.

The tragedy in Wisconsin’s Walworth County in a part of Southern Wisconsin that has long served as a favorite vacation getaway for residents of the Chicago area came with a storm that downed trees, ruptured power lines and made transportation treacherous and complicated across multiple states.
