Utility crews were scattered across Maine on Friday restoring power to tens of thousands of customers impacted by a series of powerful wind and rain storms a day earlier that caused at least one death.

By 2:30 p.m. Friday, Central Maine Power said 6,634 of its 494,880 customers were still without power, including 1,594 in Kennebec County, where 325 Winthrop, 282 Monmouth, 254 Wayne, and 158 West Gardiner customers were still in the dark in a corridor particularly hard-hit by heavy winds Thursday afternoon.

CMP had restored power to more than 85,000 customers, more than 91% of those who lost it during the storms, said Dustin Wlodkowski, a spokesperson for CMP, in a news release Friday. He said more than 26,000 customers got their power back during the overnight hours.

Wlodkowski said more than 200 line and tree crews, including some from CMP’s sister company in Connecticut, were continuing to work on power restoration. CMP expected most customers to have their lights back on by late Friday, and the rest by midday Saturday.

Wlodowski said a large tree fell on a transmission line serving 5,200 customers in Bethel.

Sam Webber, lead lineworker for CMP, said in the news release that Thursday’s storms produced more outages than any other single storm system this year.

Cameron Barker, a meteorologist with the National Weather Service in Gray, said Thursday’s storm brought a lot of wind, with gusts of 60-70 mph and even 80 mph in parts of the state. Some areas also saw downpours and thunderstorms.

He said wind speeds were high enough to bring down trees and wires, and blew a grill off someone’s deck, and a boat off a dock.

At Camp Mechuwana, a United Methodist summer camp for children on Lower Narrows Pond in Winthop, officials said on the camp’s Facebook page they had “hundreds” of trees come down in the storm and had lost power, but that otherwise campers were safe.

At Moose Mountain Adventure Park in Richmond, the storm took out 15 of the business’s umbrellas. The mini-golf business was still open Friday, and attendees were warned there would be less shade on the course.

High winds blew trees onto power lines and onto roads, including Route 15 in the Penobscot County town of Corinth. A woman was driving northbound early Thursday afternoon when a tree limb of “substantial size” fell on the vehicle, penetrated the windshield and struck her. She died at the scene, the sheriff’s office said in a news release.

A youth in the front seat sustained minor injuries and was transported to a hospital while a young child in the back seat was uninjured, the sheriff’s office said.

Severe thunderstorms made the response “somewhat difficult,” the fire department said.

A slew of public safety departments reported responding to calls for wires and trees down in roads in social media posts Thursday, from Rumford to Rockport to St. Albans.

Barker said the storm was fast-moving, so it only hit areas for a short amount of time before moving on.

In West Gardiner, Fire Chief Mike Gross said firefighters were kept busy, with 12 calls for service over about 10 hours Thursday. A couple of firefighters were still out early Friday morning, picking up equipment and cleaning up.

Firefighters put up barricades to block roads that were unsafe to travel. However, he said in a Facebook post, some barricades were removed, including those on Benson Road, which was blocked because of a broken tree leaning on live wires and hanging over the middle of the road. Gross said firefighters returned to Benson Road three times to discover the barricades had been removed. Traffic was driving under the wire-suspended tree, a dangerous thing to do, he said.

Gross said the department’s firefighters will not touch a downed tree when a wire is involved until CMP confirms it is not live.

“Your safety and our safety is worth more than anyone’s inconvenience, and that will win every time,” Gross said. “No matter how many times you pull up and yell at us, swear, squeal your tires, post on social media, or move a barricade, we are not going to change how we deal with these issues. Going forward, we will man every scene with an apparatus and personnel until it is cleaned up and safe, regardless of duration, and cost to the town, all because we cannot trust that people can or will do the right thing, and to prevent injury or death.”

Barker said the weekend forecast for central Maine includes a chance of more downpours and thunderstorms Saturday. He said smoke from wildfires in Canada is expected to be in the area as well.
