The map shows the snow forecast for the New York City area

The storm becomes a major snow event for the New York City area Friday afternoon into Saturday.

CBS News New York Reports indicate that snowfall amounts of 4 to 8 inches are expected in the metro area, while some northern communities could see up to 10 inches, with higher amounts possible locally in the Catskills and Pocono Mountains.

“Prepare for moderate to heavy snow that could accumulate very quickly — an inch or two of snowfall every hour will mean treacherous conditions on the road, poor visibility, and slippery conditions during the overnight hours,” said CBS News New York meteorologist Tony Siddiqo.

“This is going to be tough, so pace yourself,” he added.

This is expected to be the heaviest snowfall the city has witnessed in nearly four years. The last time New York City got more than 4 inches of snow was Jan. 28-29, 2022, when a powerful coastal storm dumped 8.5 inches on Central Park.

Snowfall totals are expected to be slightly lower, 3 to 5 inches, on the Jersey Shore and central New Jersey due to a mix of freezing rain and sleet.
