About 90,000 southern New Jersey customers lost power Saturday, officials said. As of last night, 50,000 remained without electricity in Cape May County, according to Atlantic City Electric’s website. The outages affected nearly 2,000 residents in Atlantic County, and scattered outages were reported in Cumberland, Ocean, Burlington, Camden and Salem counties, utility spokeswoman Sandra May said. “Overall, I think things have gone fairly well,” Gov. Chris Christie said of officials’ storm response after touring Cape May County today. The governor said he plans to declare a state of emergency and seek federal disaster-relief funding. The state is delivering 1,200 tons of road salt to Cape May, which already dropped 500 tons on areas roads since Friday. The storm’s aftermath still poses problems for the area, as heavy wet snow yesterday continued to cause tree limbs and whole trees to fall on power lines and utility poles.
