Lahser High School is still without power and classes are cancelled as DTE crews are yet to arrive, an e-mail from Principal Charlie Hollerith stated Tuesday morning. All athletic practices and after-school scheduled events for today are also cancelled.

Nearly 400 customers lost power this evening in Bloomfield Hills as high winds pick up in southeast Michigan due to the reach of Hurricane Sandy.

The largest impacted area is west of Woodward Avenue to North Adams Road between West Long Lake Road and Lone Pine Road, according to the DTE Outage Map. The power went out at about 7 p.m., and despite an initial estimate that projected restoration by 9:30 p.m. Nov. 1, the electricity appears to be restored.

The map does show another 630 customers affected in the area south of 14 Mile Road and west of Telegraph road. That outage began at about 11 p.m. Monday and no restoration estimate was available.

The outage occurred during internationally-known scholar Dr. Yong Zhao's presentation on standardized testing at the Lahser High School Auditorium.

"Electricity lost during Yong Zhao's talk. He's continuing without missing a beat, and we're all here enjoying by emergency light!" Superintendent Rob Glass Tweeted.

The National Weather Service issued a wind advisory Monday morning for all of southern Michigan, including Midland, Bay, Lenawee, Saginaw, Tuscola, Shiawassee, Genesee, Lapeer, Livingston, Oakland, Macomb, Washtenaw and Wayne counties. The advisory is in effect until 5 p.m. Tuesday.

Winds are expected to reach speeds of up to 50 miles per hour, and could cause hazardous situations—including power outages, downed tree branches, and difficulty driving, especially on east-west roads.

DTE Energy spokesman John Austerberry said that the Michigan-based gas and electric company are anticipating outages.

"We haven't seen any significant outages so far, but or meteorologist is predicting wind gusts as high as 50 miles per hour," Austerberry said Monday afternoon. "There is the likelihood that we will see some power outages as the wind starts to approach that level."

The most common cause of wind-related outages, he added, was downed tree limbs.

DTE has released around 100 contract line crews to assist with expected major outages on the east coast as Sandy hits. However, DTE's own crews will be staying in Michigan.

"We have not sent any of our own crews because we want to see what happens with the weather here," Austerberry said.

To prepare for high winds, Michigan residents are encouraged to use precaution while driving—especially high-profile vehicles. Additionally, residents are encouraged to move trash cans, lawn furniture, Halloween decorations and other outdoor items into their garage or home.
