'Dangerous' Storm Hits NYC: Latest Timing, Totals, Impacts

New Yorkers will be contending with as much as 9 inches of snow and dangerous conditions as a winter storm that is causing major disruptions for multiple states sweeps into the city on Sunday.

The city has opened warming centers and Mayor Zohran Mamdani announced the city's public schools will have a remote learning day on Monday because of the expected impacts.

The National Weather Service extended the winter storm warning to 1 p.m. on Monday, with heavy snow changing over to a heavy mix of snow and sleet in the afternoon and evening.

"Lingering significant travel impacts are likely into Monday," the weather service said.

The timing of the changeover will be the biggest factor in the total snowfall, the weather service said. Heavy snow was falling at 1 to 2 inches per hour across the area, with the sleet mix anticipated anywhere from 2 p.m. to 7 p.m.

"A 1- to 2-hour difference in the wintry mix transition timing could result in a 2- to 4-inch snow/sleet accumulation difference," the weather service said.

As of Sunday morning the weather service was predicting about 9 inches of snow in New York City.

The storm is expected to have lingering impacts on commuting, possibly even into the Monday afternoon/evening commute, the weather service said.

The storm has left dangerous ice accumulations and more than a foot of snow in much of the eastern and central United States, shutting down air travel and critical commerce corridors, Accuweather reported. Interstate 95 remains open, but many other highways that connect with New York City have bans on commercial vehicles, enacted in coordination among the affected states.

In the New York area, the Port Authority said JFK International Airport, LaGuardia Airport and Newark Liberty International Airport are open. Travelers should check with their airlines before going to the airport for flight delays or cancellations.

The MTA was urging people to avoid unnecessary travel and to anticipate disruptions on subways, buses, the LIRR, Metro-North, and Access-A-Ride because of the storm.

"If you must travel, use extra caution and check service status before you go," the MTA said.

Mamdani announced the remote learning day as snow began falling on Sunday, and said the city had prepared for the possibility ahead of the storm.

"... devices are in hand, families are informed and educators are ready to welcome students online," he said.

Students in grades 6-8 and in high school who had a previously scheduled professional learning day will continue to have Monday off, Mamdani said.

For New Yorkers in need of shelter, the following warming centers have been opened through at least Monday evening, Mamdani said.

• Bronx
  • Gompers Campus, 455 Southern Boulevard
  • DeWitt Clinton Campus, 100 West Mosholu Parkway

• Manhattan
  • Jacqueline Kennedy Onassis High School, 120 West 46th Street
  • Manhattan Center for Science and Mathematics Campus, 260 Pleasant Avenue

The snow and ice aren't the only issues with the storm. Frigid conditions are right behind and are expected to keep New York City and surrounding areas in a deep freeze through next weekend

"This is the coldest stretch since January 2018," the weather service said.

Temperatures will remain well below freezing during the day and drop into the single digits overnight. In addition, wind chills will be below zero both during the day and at night.

"Hypothermia and frostbite will occur in as little as 30 minutes if unprotected skin is exposed to these temperatures," the weather service said.
