Here’s how the latest nor’easter is affecting New York City today

Prepare for messy roads, blustery winds, and closings

The latest nor'easter to hit the east coast has officially arrived in New York City: snowfall began early this morning, and by the end of the day, there could be as much as

According to the National Weather Service's latest briefing, 10 to 18 inches of snow are possible throughout the five boroughs (and on Long Island/parts of the Hudson Valley), with snowfall coming at a rate of one to three inches per hour. The temperature is supposed to hover around freezing today, which won't help anything.

Also possible: wind gusts of up to 45 MPH, "minor to moderate" coastal flooding in low-lying waterfront areas, and the possibility of downed trees and power lines. You know the drill by now—this is the fourth winter storm we've had in as many weeks, after all.

What does this all mean from a practical, go-about your day standpoint? A whole lot, and we have the full rundown here, from school closures to MTA and airport delays.

We'll keep updating as the winter storm comes and goes, so be sure to check back to see if anything changes.

Your commute is going to be a mess

As of this morning, there are already problems—not weather-related, but still—on the New York City subway, and it's likely to get worse as the storm intensifies. MTA buses are also likely to be affected—the agency has already decided to run limited bus routes on local stops during the storm.

In terms of commuter rail, Metro-North will operate with a reduced service schedule, and trains will be running hourly in the evening. Long Island Rail Road is running normally at the moment, but that's likely to change as more snow piles up. And New Jersey Transit has put its Severe Weather Schedule into action, which means there could be changes to trains, service interruptions, and more. (There's also cross-honoring across NJT and the PATH today.)

Since the snow is expected to intensify throughout the day, keep an eye on the relevant agencies' Twitter feeds—subway, bus, Metro-North, LIRR, NJT, PATH—for details.

NYC Ferry has suspended its Rockaway route for today, but all other routes are operating as normal right now. The Staten Island Ferry is running normally.

Public schools are closed

The closure, announced by the city last night, also affects after-school programs, adult education programs, and more. A handful of city universities have also canceled classes for today, including all CUNY schools, NYU, the New School, and Marymount Manhattan College. When in doubt, check with the institution.

Many, many flights are canceled

If you were planning to fly in or out of New York City today, it's all but guaranteed those plans will change: Hundreds of flights at the metro area's three airports have been canceled, specifically 736 flights in and out of LaGuardia, 600 out of JFK, and a whopping 838 from Newark. Check with your carrier before heading out, and as with mass transit, the Twitter feeds of the three airports—JFK, LGA, and Newark—are good to check in with for updates.

Alternate side parking is suspended

Don't try to move your car for the next couple of days—alternate side parking has been suspended through Thursday, though meter rules will remain in effect.

There are plenty of plows on the streets

The Department of Sanitation hasn't made any announcements regarding trash pick-up, though food scrap drop-off is canceled today. But there are a lot of DSNY plows out on the streets—and if your car is in the way of one, it could be towed, so fair warning.

Some parks and cultural institutions are closed

While the city's bigger public parks—Central, Prospect, and the like—remain open in inclement weather, others may be closed. The High Line is one of 'em:

Park update: Due to the winter storm, the High Line will be closed on Wednesday, March 21. Stay safe and warm!

As of right now, cultural institutions like the Met, MoMA, and the New York Public Library are open, but that could change—double check beforehand if you decide to head out (but really, you should probably not try to take the subway today.)

Keep an eye on your heat and hot water

Your first instinct may be to stay indoors and burrow under a blanket, but what if the heat in your apartment isn't working? Here's everything you need to know.
