' About 4,000 DTE Energy customers, including Skyline High School in Ann Arbor, were without power at midday Tuesday, and more could lose electrical service before the day is over, a company spokesman said.

Ann Arbor Public Schools officials announced just after noon that they were closing the school for the day.

In southeast Michigan, the high winds spawned by Hurricane Sandy left 80,000 customers were without electricity, said DTE spokesman Scott Simons. Restoration estimates were not available. The utility had already restored about 30,000 customers since high winds began Monday, Simons said. Once winds drop later Tuesday, the utility expects to provide restoration estimates, he said.

Outages were dotted throughout southeast Michigan. In Washtenaw County, the largest ones were north and west of Ann Arbor. The outage affecting Skyline included 348 customers, according to the DTE Energy Power Outage map, and stretched from Interstate 94 to about Huron River Drive on both sides of Maple Road.

An outage of nearly 1,200 customers covered an area east and north of Chelsea. Smaller outages affected areas of Northfield and Salem townships.

An earlier outage affecting more than 1,500 customers in Scio Township appeared to have been restored just before noon.

Scattered problems were reported in Ann Arbor. A leaning electric pole had closed the McDonald’s restaurant on West Stadium Boulevard. Caution tape surrounded the business Tuesday morning.
