Authorities are scrambling to keep more than eight million people safe here.

And look at this live picture tonight.

Just one of the many subway entrances in New York.

This one in Times Square with a subway will shut down in about 20 minutes from now.

Throughout, this storm shut down for good.

The last passengers getting on to get home right now, right there.

Weekend anchor Dan Harris out across the city all day today.

Dan, right there in Times Square, looks pretty empty.

It does, David.

Good evening to you from the cross worlds of the world where they are right now, essentially the process of shutting this place down.

Not only are all the Broadway theater is going dark, but as you mentioned, America's largest subway system is about to halt service.

The sign over my shoulder pretty much tells the whole story.

Two words.

System shutdown normally never sleeps.

Not only are they shutting down the subways and all the Broadway shows, but they're also taping up the windows at department stores, canceling tomorrow's classes in all public schools and ordering 375,000 people to evacuate low lying areas.

If you don't evacuate, you're just putting your own life, and you're not just putting your own life in danger.

You are also endangering the lives of our first responders, who may have to come in and rescue the mayor, also warning people who live in high rises to stay away from the windows, which could be blown out by flying debris.

But the big risk to New York City is the storm surge, water gushing in from the harbor over the city's floodwalls, pouring into the subway tunnels and roads and underground power transformers, potentially causing billions and damage.

If it gets that the maximum tight, then I'm afraid we are in pretty bit trouble.

Last year, during Tropical Storm Irene, the waters came within less than a foot from topping the floodwalls.

And now sandy storm surge is predicted to be even stronger.

Since Irene failed to do the damage here in New York City that many experts predicted, some people, like the Arang family who live in the evacuation zone, are refusing to heed the warnings for Sandy.

Wait, I just hoping to make the best of it, There are long lines at the supermarket tonight.

Really mad way streets, air crackling.

Not with panic, but with a sort of upbeat, pre apocalyptic vibe.

Come on, where you wanna go, where you want to panic with New York?

Hard not to enjoy her spirit.

One last piece of news from here in New York City.

David.

The stock market.

The New York Stock Exchange just announced that it will be closed tomorrow.

They're worried about keeping the power on all day long of the resilience of that New Yorker there.

And of Dan Harris has been out there all day since.

Good morning, America, Dan.

Thank you.
