6:30 a.m. update: 42,000 Met-Ed customers in York County were still without power early Thursday morning, a full day after an ice storm took down trees and utility lines around the region.

According to the First Energy Storm Center website, areas with the largest number of people without electricity included Newberry Township, with 4,263; Springettsbury Township with 2,837; and Chanceford Township with 2,463.

PPL reported 955 customers still without power, with the largest concentration in Lower Windsor Township, wiht 683 customers out, according to the PPL website.

Midnight update: As of midnight, Met-Ed reported that 44,809 customers were still without power.

PPL said in northern York County only one customer remained to be restored, but some in Lower Windsor Township, Wrightsville, Hallam and Hellam Township could be out till Friday.

9 p.m. update: Met-Ed is reporting that 45,285 of its customers in York County are still without power.

Crews are expected to be working on the power lines throughout the night, said Chris Eck, the company's spokesman. They are working through snow, ice and fallen trees and branches to get to lines that need to be repaired, he said.

6:30 p.m. update: Met-Ed is reporting that 51,083 of its York County customers are still without power.

PPL remains on pace to restore power to its 1,500 customers in Northern York County.

Another 1,360 PPL customers in Wrightsville, Lower Windsor Township and the Hellam Township-Hallam Borough areas could have power restored by Friday.

5 p.m. update: About 1,360 PPL customers in Wrightsville, Lower Windsor Township and Hellam Township and Hallam borough areas could be without power until Friday, according to the company's spokesman Jim Nulton.

However, 1,500 customers in the Northern York County area are expected to have their power restored by 11 p.m. Wednesday, he added.

PPL's power restoration crews are working through snow and ice conditions to get the power lines working, Nulton said.

Of the customers who could be without power until Friday, 1,041 are in Lower Windsor, while 228 reside in Wrightsville and 91 live in the Hellam Township-Hallam Borough areas, according to Nulton.

Met-Ed earlier reported that nearly 62,000 were without power as of 1 p.m. Wednesday.

By 4:45 p.m., the company is reporting that 53,890 of its customers are still without power.

Earlier story: More than 62,000 York County residents were without power Wednesday afternoon, and many could go without electricity for days.

"It's going to be a multi-day event for some customers based on the scattered nature of the outages," said Chris Eck, Met-Ed spokesman.

Nearly 61,000 Met-Ed customers were without power as of 1 p.m. Wednesday, with outages reported in every municipality in the county. The heaviest outages were reported in York Township (5,490), Newberry Township (5,405) and Springettsbury Township (3,944).

PPL is also reporting more than 1,500 outages in northern York County.

The number of outages has climbed from about 50,000 Wednesday morning.

"What typically causes the number to go up are more trees falling or motor vehicles crashing into (utility) poles," Eck said.

Several hours of sleet and freezing rain left a half inch of ice on tree limbs and power lines, knocking out electricity to more than 120,000 Met-Ed customers in the region.

"Our crews are starting to make repairs and will be working all day," he said.

When crews first assessed the outages in the morning, Met-Ed reported "widespread damage" throughout its 172,000-customer territory in York County.

Much of the damage was caused by tree branches falling on wires, Eck said.

Forester crews and Met-Ed repair crews are both needed in those situations, and the work can take a while, he said.

How long it will take PPL to restore service is also unclear.

A spokesman did not return calls about restoration efforts.

PPL serves about 8,000 customers in the county.
