True, Mr G.!
That said, the bigger shows play Monday: Chicago, Mamma Mia!, Phantom etc., plus the Met Opera, Lincoln Center shows, and most off-Broadway shows.
In NYC because trash collection is halted during a severe snow storm, the city re-purposes the dustbin vans as snow plows, which are out now. They only come out once the snow has fallen, settled and reached over two inches on the roads.
The main thing is that the wind is making it extremely cold - I'd say a windchill of around -11C, set to go down to -20C later in the week.
I think US TV always overplays the weather, which then gets picked up internationally. Right now it's fine (just cold). I've been out a couple of times; I suspect I'll be able to walk out later, get a meal, get a drink and come home without any issues (assuming I don't drink too much)!
But the sad thing about NYC is that it very much depends on where you live in the five boroughs. Once the city deals with its main arteries, it does not treat all residential areas equally.
I'm in Manhattan on the Upper West Side, so near some important roads they like to keep clear: West Side Highway & Broadway. Traditionally we get plowed early and regularly, which makes everything - all amenities, stores, transport - basically run normally. But if you're in a more remote part of Brooklyn or Queens, for example, you can really be genuinely stuck for a few days.
Putting into context, I'd say the power outage in Pakistan is significantly worse than anything happening here. That said, there most likely will be a power outage in NYC somewhere, but many buildings (including mine) have generators now.
