Morristown, New Jersey – Roads and sidewalks across northwest New Jersey could turn slick within hours as freezing rain develops by early evening, raising the risk for crashes and falls during the Tuesday night commute.
According to the National Weather Service in Mount Holly, a Winter Weather Advisory is in effect from 6 p.m. Tuesday until 2 a.m. Wednesday for Morris, Sussex, and Warren counties. A light glaze of ice is expected as rain falls onto cold surfaces, creating slippery conditions on untreated roads, bridges, sidewalks, and driveways.
The highest risk window runs through the late evening, when surface temperatures hover near freezing. Bridges, overpasses, and elevated roadways in and around Morristown, Newton, and Washington are expected to ice over first, even where pavement appears wet. Side streets and residential areas may become hazardous quickly once freezing rain begins.
Local road crews are expected to monitor conditions, but motorists are urged to slow down, increase following distance, and avoid sudden braking. Pedestrians should use handrails, wear footwear with traction, and use caution on steps and walkways.
Conditions improve after 2 a.m. Wednesday as temperatures rise slightly, though isolated slick spots may linger into the early morning hours. Additional advisories could be issued if ice develops more quickly or becomes more widespread than expected.
