More than 50,000 homes were left without power Monday night as heavy winds ripped through Southwest Michigan and Northern Indiana, which caught the tail end of a powerful derecho storm that swept across the Midwest.

By 5 p.m. Tuesday, Indiana Michigan Power crews had restored electricity to about 50 percent of the 51,875 customers who lost service Monday. I&M said it had sent out more than 900 employees, contractors and personnel from other power companies to assist with the restoration effort Tuesday.
