LAKE COUNTY -- It's happening again. Thousands of residents in Lake County were without power Saturday afternoon.

According to FirstEnergy spokesperson, Mark Durbin, all power has been restored to the areas affected.

A FirstEnergy spokesman said a failed insulator was to blame and the problem affected two different power lines, causing the widespread outages.

He also said this week's problem is not at all related to last weekend's outage, describing the back-to-back weekends of darkness as "coincidence."

As many as 50,000 FirstEnergy customers were without power during the early hours of the outage. About 22,000 of those customers were in Mentor, and nearly all of Painesville Township and Perry were without power.

Ashtabula County also had around 4,500 FirstEnergy customers without power at its highest.

According to the Painesville Police Department Facebook page, the City Hall lobby will be opening as an emergency warming center for those needing a temporary place to stay.
