Governor Phil Murphy said the biggest concerns are travel conditions in the north and northwest parts of the state, as well as a risk of coastal flooding further south, and strong and potentially damaging winds that can bring down trees and power lines.
The biggest concern for coastal flooding is the Jersey shore, where high tide and dangerous storm surge is a possibility.
Officials urged drivers to stay off roads Monday.
A State of Emergency has not been issued for New Jersey, but Governor Murphy warned that a potentially dangerous mix of precipitation is possible depending where you are.
"That combination -- risk of power outage, risk of coastal flooding, maybe even some inland flooding -- the combination of all that is why we are here today," Murphy said. "Not that any one piece of it looks like it is for the record books, but the combination adds up to a really messy 14 to 16 hours."

At a noon briefing Sunday, New York Governor Kathy Hochul encouraged New Yorkers to get any holiday weekend travel out of the way ahead of the storm system heading to the state overnight.
"If you have any travel to do for this holiday weekend, please do it today," Hochul said. "The earlier hours before this all starts up this evening. Because overnight's going to be very unpredictable. And with the darkness and ice on the roads and high winds, this could be a very dangerous situation."
