In Lancaster and York Counties, the American Red Cross shelters are still open for those who lost power. Organizers expected to meet a higher demand for help Thursday night.
"Homes are really starting to lose their heat now and folks are getting cold," Kathy Smyser with the American Red Cross said.
In East Hempfield Township, Lancaster County the shelter at Living Hope Community Church had five people stay the night.
The shelter included aid for pets.
In York County, a shelter was also up and running at the York County School of Technology. Twelve people stayed there Wednesday. Again, on Thursday organizers anticipated more.
Terry Yohe of York said he came on Thursday because he just could not bear to spend another nigh in his cold house.
"I was sleeping with my clothes on, my jacket on, it just wasn't very comfortable," Yohe said.
Met-Ed/First Energy and PPL both said they expect power to be restored to 90 percent of customers by Friday evening.
