Reception centers are just that - reception - that's where you get put on the bus for transport to the shelter - where do you stash 100K people for a couple of weeks? ALL OVER the place - Schools, Malls, Madison Square Garden, etc etc etc - I think the location list is over 200 long
The subways will probably go down - they did in the unnamed storm - the generator plant that makes the 25Hz power for the signals flooded
Bridges will have to close 2-4 hrs before landfall due to wind - remember, all of NYC except for The Bronx is on islands - what joy
The GOOD news is post the storm - we should be able to transport rescue stuff in by barge
