The advisory calls for freezing rain and accumulations of around a trace of ice. Freezing rain is expected to fall in the morning, and switch over to plain rain by the late morning hours.
The forecast calls for icy conditions to result in hazardous travel, particularly on bridges, overpasses and untreated roads.
The advisory was issued at 8:57 a.m., following a day in which an unexpected snowstorm blanketed much of New Jersey. The Winter Weather Advisory means periods of snow, sleet or freezing rain will cause difficulties traveling.
The National Weather Service calls for slippery roads and limited visibility, and warns drivers to use caution on the roadways.
Speed restrictions are in place around the George Washington Bridge, Bayonne Bridge, Goethels Bridge and the Outerbridge Crossing, according to 511nj.org.
