(AREA) -- More than 200,000 Michigan residents remain without power after a weekend ice storm blacked out close to a half-million homes and businesses across the state. The wintry blast hit Saturday night, and three utilities said about 251,000 of their customers still are without service. The utilities have said it would take days before most power was restored because of the difficulty of working around ice-broken lines. DTE Energy said this afternoon that work continues to restore service to 55,000 blacked-out customers out of about 150,000 affected since the storm hit. DTE says around 25,000 customers in Lapeer County are still without power, 1,115 in Tuscola County, around 1,650 in Sanilac County and 100 in St. Clair County.
