As the first measurable snow moved through the region in almost a year, Philadelphia reported less than two inches, while areas of South Jersey were hit with more than a foot by early Monday evening.

And with temperatures expected to drop to the teens in some places, officials warned about treacherous travel.

Absecon in Atlantic County recorded 13 inches, New Jersey Gov. Phil Murphy said at a late afternoon briefing.

Murphy called it a “very, very substantial snowstorm” for parts of South Jersey, especially for areas close to the Shore.

Atlantic City International Airport shut down Monday afternoon, and officials said they would reassess conditions around 9 p.m.

Reduced speed restrictions were in place along the Garden State Parkway south of Toms River. As of late afternoon, there were 160 vehicle accidents statewide and 245 incidents of motorists requiring aide, mainly from spinouts, said State Police Superintendent Patrick J. Callahan.

“Temperatures will fall into the teens tonight as skies clear behind the departing storm. Areas with fresh deep snow on the ground may reach into the single digits. Roads will become icy overnight where the snow has fallen, so use caution if traveling,” the National Weather Service in Mount Holly wrote on Twitter.

Transportation Commissioner Diane Gutierrez-Scaccetti said salting operations would continue overnight.

“If you can, please stay off the roads,” Murphy pleaded.

Winslow Township reported the most snow in Camden County with 5.5 inches. The same amount fell in Franklinville in Gloucester County. The totals stayed below three inches in Burlington County.

The top total in Delaware was 13 inches in Kent County.

Philadelphia and its Pennsylvania suburbs saw little snow: A half inch was recorded at Philadelphia International Airport and 1.8 inches in the Point Breeze neighborhood in South Philadelphia, with nothing more significant in the neighboring counties.

At 12:01 a.m. Monday, New Jersey’s emergency operations center was activated and Murphy had calls with local and county leaders in South Jersey during the morning. State workers had a delayed 10 a.m. start to the day.

“They are getting clobbered in the south,” Murphy said as snow was continuing to fall Monday afternoon. “If you’re down there, stay strong.”

Route 40 was closed in both directions near the Shore because of flooding.
