Areas of northern and central New Jersey are now bracing for even more snow than originally forecast, as a major and prolonged winter storm in the northeast is expected to hit the state from Sunday to Tuesday, potentially drop as much as 18 inches in some areas, according to the forecast update.

The first projections of 8 to 12 inches of snow have now jumped to 12 to 18 inches in several counties, including Mercer, Middlesex, Monmouth and Morris, according to the National Weather Service. Early projections of 6 to 8 inches of snow dropped to 8 to 12 inches in Sussex and Warren counties.

Snow projections for Bergen, Essex and Passaic counties were between 20 and 10 inches on Saturday morning. They have also been increased to 12 to 18 inches in a forecast map (displayed below) which was updated at 4:30 PM.

Snowfall forecasts have dropped in parts of southern Jersey, which could be affected mainly by a mixture of snow, sleet and rain. Projections in the Vineland area of ​​Cumberland County fell from 6 to 8 inches to 4 to 6 inches, and the Toms River area of ​​Ocean County fell from 6 to 8 inches to 3 to 4 inches.

The storm could also cause coastal flooding and strong wind gusts, potentially leading to power outages. Travel is also expected to be difficult due to blowing snow and blowing snow.

The National Weather Service has placed much of New Jersey on a winter storm warning. The agency warns that road conditions are likely to be dangerous from Sunday evening to much of Monday.

“Traveling can be very difficult if not impossible,” according to the warnings.

Here’s a look at the forecast for Saturday afternoon.

The greatest amount of snow is expected in eastern Pennsylvania and central and northern New Jersey, the National Weather Service said in its 5 p.m. storm briefing. But the exact path of the storm remains uncertain. A shift could bring heavier snow further north or south, the agency said.

Precipitation is expected to start Sunday evening through Monday morning. Snow is expected to be heaviest during the day Monday, with rates exceeding 1 inch per hour at points. Snow will likely continue on Tuesday, although accumulation will be limited by then.

STRONG WINDS

Forecasters are calling for strong winds, particularly near the coast and over water, with gusts reaching 40 to 50 mph on Monday. This, they said, could lead to power outages.

Gusts inland could reach 35 to 45 mph, hampering movement with reduced visibility, as well as blowing snow and blowing snow.
