A storm system that brought a tornado to Lorain and northern Medina counties also cut power to thousands in Summit and Portage counties overnight on Tuesday, and some customers were expected to be without power into Thursday.

According to the National Weather Service’s Cleveland office, an EF-1 tornado with winds in excess of 100 mph was determined to have traveled just over 11 miles in 10 minutes, from the center of Grafton Township to just short of Fox Meadow Country Club. The storm was reported at about 11:30 p.m. Tuesday.

High winds also resulted in damage across Summit County, where First Energy Corp. reported that just under 11,400 Summit County customers remained without power around 5 p.m. Wednesday. Most of those Summit County outages reported Wednesday morning were in Coventry Township, Barberton and Akron.

As of 7:20 a.m. Wednesday morning, FirstEnergy was reporting more than 45,000 people without power across its Ohio coverage area, mostly in Northeast Ohio.

More than 4,000 people lost power in Portage County, with about 1,700 of those in Deerfield Township, and another 1,000 in Palmyra Township.

In Stow and Tallmadge, 443 and 280 customers respectively were still without power late Wednesday afternoon.

Due to a large number of storm-related outages, FirstEnergy says the estimated restoration time for these communities was not until 11:30 p.m. Thursday at the latest

A total of fewer than 30 customers were without power in Cuyahoga Falls, Munroe Falls, Northfield Village and Sagamore Hills.

A small outage was reported earlier in the day in Macedonia, but FirstEnergy was no longer reporting anyone without power in the city by late afternoon.

Stow Police Capt. Bryan Snavely said Wednesday afternoon that police dispatch received a total of 14 storm-related calls.

"We had numerous trees down, power lines down, standing water on Route 8," said Snavely, adding that the water shut down one of two lanes in Route 8’s southbound construction zone from about 12:30 to 5:30 a.m.

Cuyahoga Falls city spokeswoman Kelli Crawford-Smith said Wednesday morning that just two of the city’s electric utility customers were still without power, down from a high of a little over 3,000 customers during the night. Both customers are on Gilbert Road in Stow, near the border with Cuyahoga Falls, and restoration of power was imminent, she said. The city’s outages were caused by trees and branches down throughout the city, but the city had not been notified of any other property damage, said Crawford-Smith.

Tallmadge Police Chief Ron Williams, also on Wednesday morning, said trees and power lines came down, primarily in the city’s northeast quadrant, with North Munroe Road north of the roundabout closed due to a fallen tree and power lines.

"Pretty big trees down," said Williams. "It was a pretty substantial storm. The initial gust was tough."

Hudson city spokeswoman Jody Roberts said there were no outages among city electric utility customers and the city had not received any reports of damage.

Twinsburg and Macedonia dispatch centers say they did not have any information about storm damage.

Tom King, a meteorologist at the National Weather Service in Cleveland (NWS), said thunderstorms developed over Michigan moved south and across the area. He said the storms started as individual, but developed into a line of thunder storms hitting all of Northern Ohio.

Winds reached a high of 67 mph at Akron-Canton Airport just after midnight. Winds in Kent got up to 58 mph, and gusts hit 60 mph in Canton, according to the National Weather Service.

Hail and fallen trees were also reported throughout the area.
