A strong winter storm last night dumped heavy snow on New York and New Jersey, also pummeled by Hurricane Sandy last week – even forcing FEMA to shut its doors to families in need.
FEMA shuttered its recovery centers, which were set up to offer assistance to those most affected by the monster storm, and the Staten Island office closed “due to bad weather”.
The Nor’easter rattled the East Coast with high winds and piles of wet, slushy snow on Wednesday – leaving thousands of Sandy victims without power just after it had been restored.
Adding to the mess, the three major airports in the tri-state area closed, commuter trains slowed service, and mass transit lurched to a halt, inflicting another round of misery on the city’s residents.
The storm dropped nearly four inches of snow in Central Park, which areas of southern New Jersey suffered more than 9 inches, the National Weather Service said.
Residents from Connecticut to Rhode Island were also slammed with up to six inches of snow, while areas of Massachusetts had a whopping eight inches.
Carrying gusts of 60 mph, the storm brought down tree limbs and electrical wires damaged by Sandy. Utilities across the two states in New York and New Jersey reported that nearly 60,000 customers who lost power in the superstorm lost it again.

The provincial governor’s office said another six people were injured when the snow hit a village in Shekay district, near the Tajikistan border.
The village had been wiped away, said spokesman Abdul Marouf Rasikh.
Badakhshan is one of the country’s poorest and most remote regions and is shut off by heavy snow every year.
The village had been severely affected by the cold weather, said Abdul Marouf Rasikh, and governor Shah Wali Ullah had been visiting at the time.
“The governor was trapped with those six injured but was rescued by helicopters and taken to a remote area on the border with Tajikistan,” said Abdul Marouf Rasikh.
