8:45 a.m. update: Power out for about 2,000 DTE Energy customers after Dexter tornado

About 3,000 customers were without power in all of DTE's service area in southeast Michigan, said spokesman Len Singer.

Most customers should get power back Friday, DTE said. Full restoration will depend on the extent of damage to the system, DTE said in a press release.

Singer said it could have been much worse.

"I was pleasantly surprised," he said. "We would have expected to see more damage than we did with the storm that went through."

The DTE power outage map showed about power out in large areas of Dexter. Power also appeared out in an area along West Stadium Boulevard in Ann Arbor hit by heavy flooding Thursday.

Crews worked through the night to clear debris, assess damage and make repairs, DTE said.

Customers are cautioned to stay away from any downed power lines, or anything in which a downed line may be in contact. Assume all lines are energized and dangerous, and stay at least 20 feet away, DTE warned.

Customers should call DTE Energy at (800) 477-4747 to report a power outage or a downed power line.
