HOUGHTON — Thunder and lightning hit the Keweenaw over the weekend, leading to widespread outages and downed trees.

With a low-pressure system in place, a cold front moved through late last night, bringing unstable weather ahead of it, said Jacob Horton, a meteorologist with the National Weather Service in Negaunee.

Widespread outages occurred around 1 a.m. as thunderstorms were at their peak. The Upper Peninsula Power Co. reported 1,000 customers remained without power as of 8 a.m. About 270 customers remained affected by 2:30 p.m., mostly in Baraga County.

A number of downed trees were reported on backroads, the Houghton County Sheriff’s Office reported, while no issues had been reported to the Keweenaw County Sheriff’s Office. In Baraga County, Jurmu and Beartown roads were impassable because of downed trees, according to the Keweenaw Bay Fire Department. Ontonagon County reported multiple incidents of downed trees falling on power lines.

There were scattered reports of hail, including some in Houghton the size of a quarter. The L’Anse area saw the highest winds, with gusts reported up to 68 mph.

Though Saturday night’s storms were the largest, some also occurred the night before. Saturday morning, the Quincy-Frankin-Hancock Township Fire department was called out to a home on Forsman Road damaged by a lightning strike, said Assistant Chief Eric Bradfish. There were no injuries, while the amount of damage had yet to be determined.

Assisting were the Boston and Dollar Bay fire departments, Houghton County Sheriff’s Office, Mercy EMS and UPPCO.

The next chance of showers is Tuesday into Tuesday night, Horton said. Another chance of rain comes later this week.
