Utility workers struggled Friday to continue repairing downed power lines, but hundreds of thousands of people remained without electricity two days after a major storm swept through Pennsylvania and Maryland.
More than a foot of snow fell in many areas of the Northeast in the second of two snowstorms this week. On Friday, biting cold moved through the mid-Atlantic region, complicating repair work.
Utility companies reported more than 325,000 customers without power in Pennsylvania, along with about 50,000 in Maryland. Officials have said they expected some of the work will have to continue through the weekend before power is fully restored.
Pennsylvania Gov. Tom Corbett toured the area by air on Thursday.
"This storm is in some respects as bad or maybe even worse than Hurricane Sandy," Corbett told reporters during an appearance in the Philadelphia suburbs. Earlier in the week, he had declared an emergency.
A third storm is forming in parts of the lower Midwest and is likely to hit the Northeast by the weekend and into the early part of next week.
