Outdoor subway service in New York City was suspended starting at 2 p.m. on Monday because of the snowstorm, officials said.
There were no immediate plans to pause underground service, but that could change, said Sarah E. Feinberg, the interim president of New York City Transit, which runs the city’s subway and buses.
“This is a dangerous, life-threatening situation,” Gov. Andrew M. Cuomo said at a news conference on Monday. “And expect major closures, so you’re not surprised. And we don’t want anyone to be stranded in a location where they can’t get home again.”
The shut down affected lines across the city and closed 204 of the system’s 472 stations, mostly n Brooklyn, Queens and the Bronx, according to a map shared by the Metropolitan Transportation Authority. Passengers were required to disembark at the last underground station before the train goes above ground.
Southbound service on the F line ended in Brooklyn at the Jay Street-MetroTech station, for example. In Queens, the 7 line ended northbound service at Hunters Point Avenue. In the Bronx, northbound service on the 6 line ended at Hunts Point Avenue.
Patrick J. Foye, the chairman of the Metropolitan Transportation Authority, which oversees the subway, buses and two commuter lines, said the Long Island Railroad would stop running between 2:30 p.m. and 3:30 p.m., while the last Metro-North Railroad trains would leave Grand Central Terminal around 3 p.m.
PATH trains, which link Manhattan with New Jersey, would also stop running at 3 p.m., according to Rick Cotton, executive director of the Port Authority of New York and New Jersey
The M.T.A. previously suspended above ground subway service — while keeping underground service running — during a blizzard in January 2016.
But the only time the whole subway system was closed because of a snowstorm was in 2015, when Mr. Cuomo ordered it shut down at 11 p.m. on Jan. 26. The announcement caught transit workers by surprise and they were forced to scramble to bring the vast network to a halt within hours.
Mayor Bill de Blasio said he found out about the closure when the public did. And the storm largely spared the city; the subway started to slowly reopen the next day, though the closure had disrupted the city’s economic life.
The subway was also closed in August 2011 ahead of Tropical Storm Irene and in 2012 ahead of Hurricane Sandy.
In the spring, officials decided to halt regularly scheduled overnight service for the first time in the M.T.A.’s history, shutting the system down from 1 a.m. to 5 a.m. to disinfect trains, equipment and stations during the pandemic.
