EDISON - Gov. Chris Christie updated New Jersey residents this morning on the aftermath of Hurricane Sandy.

The governor says the devastation at the New Jersey shore is "unthinkable."

Christie says the first priority for officials is to try to rescue those still stranded by floodwaters on barrier islands and elsewhere.

He says the full extent of damage will not be known for another day or two.

He says parts of amusement piers at Seaside Heights have washed into the Atlantic Ocean, railroad bridges are badly damaged, train tracks on the North Jersey Coast line have been swept away, rail cars were carried by floodwaters onto the New Jersey Turnpike and homes were swept off their foundations in Ocean County.

Christie is asking private employers statewide to let workers stay home today as road crews can begin to clear.

At least three deaths in northern New Jersey are linked to the storm.

Authorities in Morris County say a man and a woman died after a tree fell on their pickup truck yesterday evening in Mendham Township. Two children in the pickup were injured. Officials in Hawthorne say a 77-year-old man was killed when a tree crashed into his home.
