Strong winds that whipped through Metro Detroit on Thursday diminished, prompting the National Weather Service to downgrade its high wind warning to an advisory.

“It was a little bit weaker of a system than we had originally expected,” said Rachel Kulik, meteorologist with the National Weather Service.

Winds of 35-40 mph are expected Friday.

The winds caused power outages for nearly 6,000 homes serviced by DTE Energy and Consumers Power.

According to the weather service, wind gusts peaked at 52 mph at Detroit Metropolitan Airport at 10 a.m., while winds of 49 mph and 43 mph were recorded respectively at City Airport and in Pontiac.

The NWS issued a hazardous weather warning for portions of southeast Michigan into Friday morning.

The NWS also issued storm warnings for portions of Lake Erie and Lake St. Clair, as well as gale warnings for Lake Huron, including Saginaw Bay.

The National Weather Service in Grand Rapids said a gust of 48 mph was reported Thursday in South Haven along Lake Michigan in the southwestern part of the state. Gusts of 46 mph are reported in Holland and 41 mph in Grand Rapids.

A check of the DTE Energy map Thursday afternoon showed a scattering of outages across Metro Detroit.

DTE is keeping an eye on the storm front, according to spokesman Scott Simons.

“In cases like this, we put an in-depth emergency plan in place,” said DTE spokesman Scott Simons.

“That plan allows us to prepare for, and react to, severe weather that has the potential to interrupt electric service for our customers.”

DTE also has its own company meteorologists who track and monitor the weather.

“That allows us to alert our employees as much as 24 hours before a storm passes through,” Simons said.

“We also stay in contact with other utility companies farther west, such as Consumers, which are also in the path of the storm so we can see what kind of damage they’re seeing.”

A check of the Consumers Power outage map Thursday afternoon showed a loss of electricity to about 4,850 homes and businesses statewide.

According to the NWS, gale force winds on Lake Huron could produce waves in the 12-15 foot range Friday in an area from Presque Ile to Port Austin.

A check of the NWS station at Grand Rapids on Thursday showed storm warnings in effect from Pentwater to St. Joseph on Lake Michigan, with predictions of wind gusts of up to 50 mph.

The high winds are expected to produce waves of up to 13 feet.

The Mackinac Bridge Authority issued a high-wind warning to vehicles preparing to cross the bridge Thursday.
