Between 1 and 4 inches of snow, sleet and freezing rain were predicted for Morris and Warren counties Tuesday night, according to a winter weather advisory issued by the National Weather Service (NWS).
The nighttime hours featured a wintry mix of precipitation—primarily freezing rain mixed with some snow as of midnight—that made roads slick and driving treacherous.
The "hazardous" weather is expected to continue until 11 a.m. Wednesday. Ice could accumulate to half an inch.
"The precipitation is expected to change to a mix of snow and sleet overnight," the NWS said Tuesday. "The wintry mix is forecast to change gradually back to all rain during mid- to late-morning hours on Wednesday before ending."
The NWS said rain and sleet could cause hazardous road conditions for the Wednesday morning commute. Northeast winds could reach up to 5 mph and temperatures are predicted to be in the low 30s.
"Be prepared for slippery roads and limited visibility. Use extra care if you will be driving," the NWS said.
