The calendar says March but more winter weather has made for slick driving across the state.

New Jersey Department of Transportation crews hit the roads on Sunday morning spreading salt and will begin plowing as snow accumulates in North and Central New Jersey.

"Our biggest concern is icing conditions later this afternoon and evening," said NJ DOT spokesman Stephen Schapiro "As the snow turns to freezing rain we expect difficult driving conditions and recommend people stay home."

Meteorologist Dan Zarrow shares the concern about icing.

"Freezing rain is admittedly one of the hardest weather phenomena to predict, since the conditions at the surface and up in the atmosphere have to be perfect… Just a bit too warm, and it will be just plain rain… Just a bit too cold, and the precipitation stays as sleet or snow. But this setup looks close enough to the sound the alarms yet again for significant icing somewhere in New Jersey," Zarrow said.

As the roads became slick on Sunday afternoon, Ocean Township Police in Monmouth County posted a pictures of a car that slid into a restaurant called Slices on Norwood Avenue.

Speeds are reduced along the New Jersey Turnpike, Garden State Parkway and Atlantic City Expressways where numerous minor spin-outs have been reported to New Jersey Fast Traffic.

NJ Transit will be cross-honoring tuckets on rail, bus, light rail and private bus carriers on Monday.

More than 200 flights in and out of Newark-Liberty, Philadelphia, LaGuardia and Kennedy airports have been canceled or delayed, according to FlightAware.com.

JCP&L tweets it is preparing for possible outages due to heavy icy accumulation and warning customers to be ready with flashlights, extra blankets, a stock of foods that don't require heating, charged up cell phone and a first aid kit.
