In other preparations, nearly 500 Department of Transportation workers began treating bridges and overpasses, and emergency crews filled more than 1,000 potholes. And the city’s Office of Emergency Management was coordinating with dozens of local, state and federal agencies.

The agency would be ready to open temporary shelters and had arranged for the use of “high-axle” vehicles owned by the National Guard that could be used to assist emergency medical technicians navigating snow drifts.

All city buses will be equipped with snow tires or chains by Monday afternoon, Mr. Cuomo said. Bus service will proceed on Monday morning as usual, but Metropolitan Transportation Authority officials may make scheduling adjustments as the storm progresses.

The authority will begin storing subway cars underground on Monday night, Mr. Cuomo added. De-icers and snow throwers will be deployed and extra crews will be on duty.
