TRENTON -- The threat of icy roads delayed the opening of school for a number of districts.

Roads are down to the blacktop in most areas following Thursday's storm, which left anywhere from 8 to 11 inches of snow across Sussex, Warren, and Morris counties, to 4 to 7 inches in Monmouth County and across Central Jersey, to 1 to 3 inches in South Jersey, according to the National Weather Service.

Most highways also are down to blacktop, but some untreated roads and areas where snow blew back onto the pavement created the threat of black ice, especially on secondary roads, bridges, and overpasses.

As a precaution, many districts, mostly in Monmouth, Morris, Somerset, and Union counties, delayed the start of classes on Friday.

"Although the main roads are in good condition, the side streets and walkways are icy. More time is welcome, especially for teachers and bus drivers. It is completely understandable that districts are on delayed openings," New Jersey Fast Traffic's Bob Williams said.

"There are two big issues at play this morning. First, the rain that preceded the snow early Thursday morning caused a layer of ice to form underneath the snow cover. Additionally, frigid temperatures on this Friday morning have forced any water from ice melt to refreeze. The walk to the car or bus stop will be particularly treacherous," New Jersey 101.5 Chief Meteorologist Dan Zarrow said.

The bitter cold doesn't help, with temperatures on Friday morning in the teens, and the wind creating a wind chill in the single digits.

"It’s definitely a 'bundle up tightly' kind of morning – although it’s not quite 'dangerous' cold, you’ll be wise to dress in layers and cover up as much exposed skin as possible before opening the front door," Zarrow said.

New Jersey Transit reported 15-minute delays on all rail service on Friday morning, and continued to cross-honor tickets on trains, light rails, and buses.

Outage maps for PSE&G and JCP&L were not showing any significant outages.
