Snow started falling on the five boroughs Sunday morning and conditions are expected to worsen by the afternoon.

Six to eight inches are expected to accumulate in total, and some spots could see up to 10 inches. The storm is forecast to move out by 9 p.m. Sunday, with the heaviest snowfall expected in the afternoon and evening.

“It is brutal, it is bonechilling and it is dangerous,” Gov. Kathy Hochul said at a briefing Sunday.

Hochul said the state is expecting the longest cold stretch and the highest snow totals in years. In the city and on Long Island, snow is falling at a rate of one to two inches an hour, with 30 mph wind gusts possible.

Hochul said officials are not expecting mass power outages. However, isolated incidents are possible.

Mayor Zohran Mamdani has urged New Yorkers to stay indoors if possible, and use mass transit if travel is necessary.

Ice and sleet will mix in with the snowfall during the storm, making conditions especially hazardous.

Mamdani announced city public school students will have a remote day Monday.
