As of Sunday evening, 15,500 BWL customers were without power, which could be restored as late as Monday, said Mark Nixon, director of communications for the BWL.

The BWL can restore electricity to the point of reaching the house, Nixon said, but damages on the actual house or in-house power is the homeowner’s job.

“Another weather system is heading our way, we’re expecting thunderstorms and high winds,” Nixon said. “Hopefully we won’t be back at square one after tonight.”

A spokesperson for Consumers Energy said they were also unable to comment on the storms’ effects on their customers, as all staff were busy handling customers’ inquiries.

About 35,000 Consumers Energy electric customers are still without service due to thunderstorm activity that moved across the state on Friday and Saturday, according to a press release. Since Friday, more than 162,000 customers have been affected with weather-related outages.

As of 5 p.m. Sunday, Consumers Energy estimated about 15,500 customers remained without electric service.

Since the storm hit Saturday night, all available BWL crews have been working around the clock to help clean up fallen tree limbs and other damages, Nixon said.

The worst of the day’s storm is moving east, away from East Lansing, but another round of storms could arise, probably in the northern part of the state, according to the National Weather Service.

There’s a fairly pronounced squall line, or far-reaching and narrow line of thunderstorms, in the southern two-thirds of the Lower Peninsula, said Dave Lawrence, meteorologist for the National Weather Service Forecast Office in Gaylord.

“These things are notoriously impossible to predict,” Lawrence said. “But this is definitely on the way out.”

The National Weather Service Forecast Office in Grand Rapids could not be reached for comment.
