[UPDATE BELOW] In case the piles of pollutant-covered snow that are now sitting beneath piles of trash on your block weren't enough, it is officially snowing again. NYC can expect around six inches of snow on Sunday, according to the latest update from the National Weather Service.

Eastern Long Island and southeastern Connecticut could see up to nine inches. Much of the area has been placed under a winter storm warning until 9 p.m. this evening.

As of Sunday afternoon, New York state planned to close two vaccine sites at Stony Brook and Jones Beach on Long Island, with appointments to be rescheduled in the coming week, but all others remained open. Governor Andrew Cuomo said Saturday the heavy snowfall and high winds could result in power outages on Long Island.

The city's Sanitation Department began preparing Saturday by salting and brining the streets. Snow plowing begins once there's 2 inches of snow on the ground, the agency said.

Emergency snow laborers would be out Monday, after the snowfall is expected to stop, according to Sanitation Commissioner Ed Grayson. He said the sanitation department anticipates challenges with the existing snow build-up. Workers had started to catch up on trash collection from Thursday to Saturday, but with more snowfall, trash and recycling pick-ups will again be delayed.

The city's open restaurants program is closed today due to plowing, though sidewalk dining specifically is still open, Mayor Bill de Blasio said on NY1 Saturday evening.

Vaccination sites were expected to remain open, and schools were expected to be open Monday too, de Blasio said.

The MTA said regular Sunday schedules will continue, though articulated buses (the accordion-style ones) will be replaced with local buses fitted with snow chains. NYC Transit is prepared to deploy snow blowers and de-icing subway cars to keep the outdoor tracks cleared of snow and ice.

De Blasio said on NY1 the snowfall is expected to be "much smaller" than last week's snow storm.

I can personally confirm the snow is falling hard enough in Brooklyn that I'll soon stand up from my hunched-over writing position to stretch my back and look out the window to say, "It's really coming down out there!" before sucking down a cup of coffee and refocusing my gaze on this computer screen.

Update 2 p.m.: Snow is still falling as of 2 p.m. on Sunday, and the National Weather Service reports three inches of fresh powder have accumulated in Central Park:

The heaviest snow is now pushing east into Long Island. The winter snow warning remains in effect until 9 p.m. Sunday.
