Bucks and Montgomery County Patch staff will be updating this map throughout the day on Monday to reflect the developing impacts of Hurricane Sandy.
According to some estimates, more than 10 million people were predicted to lose power in the Northeast as the storm progresses.
Full restoration of power to the Bucks County and Montgomery County areas may take up to a week to complete, according to PECO.
PECO reports more than 850,000 customers are without power on Oct. 30. That makes it the most damaging storm in the company's history.
