Newton, New Jersey – Snow begins falling by 10 a.m. Sunday, and up to 18 inches could bury northwest New Jersey before the Monday evening commute ends, threatening major highways and power lines.
According to the National Weather Service in Mount Holly, a Winter Storm Warning is now in effect for Sussex, Warren and Hunterdon counties from 10 a.m. Sunday until 6 p.m. Monday. Forecasters expect total snowfall between 13 and 18 inches, with wind gusts reaching 45 mph. The combination will create blowing snow, sharply reduced visibility and the potential for downed tree branches.
The storm will have statewide ripple effects, but the heaviest impacts focus on higher elevations in Sussex and Warren counties. Interstate 80, Route 206 and Route 46 could become snow-covered Sunday afternoon, with drifting likely overnight. In Newton, Washington and Flemington, snowfall rates may intensify late Sunday, quickly covering untreated roads before the Monday morning commute. Gusts near 45 mph could snap weakened branches and cause isolated power outages.
Travel could become very difficult to impossible at times, especially late Sunday night through midday Monday. Residents should avoid non-essential travel, charge devices and check New Jersey 511 for live road updates. The warning remains in effect until 6 p.m. Monday, and additional advisories could follow if winds strengthen further.
