Utilities say they'll be working at least one more day to restore power to remaining Michigan homes and businesses still without service following this week's severe thunderstorms.

Storms moved through the state late Monday and early Tuesday, toppling trees and knocking out power to at least 247,000 customers. Storm debris damaged property and blocked some streets in western Michigan, while heavy rains flooded some roads.

DTE Energy Co. says about 1,000 customers were without power early Thursday after 140,000 lost service. It expects to have all of the power back on later Thursday.

DTE Energy offers this power outage map to help customers track outages.

In an update late Wednesday, Indiana Michigan Power says about 14,700 of its 37,000 affected Michigan customers were still offline. CMS Energy Corp.'s Consumers Energy unit says Wednesday about 19,000 of its 70,000 affected customers were without power.
