NEWARK - Gov. Chris Christie declared a state of emergency for New Jersey Friday night as a powerful snowstorm moves across the Garden State.

As part of the state of emergency, the governor authorized New Jersey Transit to shut down at 2 a.m. Christie said this would give the transit agency time to assess their system and clear roads and tracks as needed.

He said NJ Transit will then have the option to resume a normal weekend schedule as needed. New Jersey Transit will cross-honor tickets Saturday and Sunday due to the storm.

The National Weather Service issued a blizzard warning for the majority of the state through Sunday. Parts of the state could see as much as 2 feet of snow.

The National Weather Service also issued a coastal flood warning along the state’s coastline. The storm, coupled with this weekend’s full moon, could cause tidal flooding and large storm surges.

Several Jersey Shore towns have issued voluntary evacuations. Barnegat officials issued a mandatory evacuation.
