About 136,000 customers were without power Monday afternoon because of an icy winter storm that struck Michigan overnight.
DTE Energy said it was working to restore power to 90,000 customers in southeastern Michigan, while Consumers Energy had 46,000 customers without service throughout the southern part of the state.
Consumers said residents in the hardest-hit areas, including Jackson County, may not receive electric service until Wednesday. Other Consumers customers in southern Michigan were expected to have power restored by Tuesday.
DTE said it hoped to restore power to a majority of customers by late Monday, but it expected to continue working through Tuesday as well.
More snow, freezing rain, ice and wind could delay how quickly power is restored.
"We are suffering from the impact of heavy ice on tree branches that continue to break and fall on (power) lines," DTE spokeswoman Lorie Kessler said.
As much as a half-inch of ice covered trees, roads and power lines in southern Michigan, while up to 5 inches of snow blanketed Muskegon and other areas in the southwestern part of the state.
Meteorologist George Wentzel at the National Weather Service told The Muskegon Chronicle that Muskegon-area residents could expect an inch or so of snow each day into next week.
In the Detroit area, roads were wet but mostly clear except for downed trees and power lines.
