NEW YORK CITY, N.Y. -- Sandy only lasted a few hours, but the damage she left behind will take months to clean up after. A record 13-foot surge of seawater has flooded the New York City’s historic waterfront, subway tunnels and cut power to hundreds of thousands of people.

There was an explosion at a ConEd building near 14th Street. Parts of the city started to go dark soon after. ConEd reports more than a half million people are without power in the New York City area. That could take up to a week to restore.

It was pandemonium at New York University Medical Center overnight. About 200 patients had to be moved late last night after backup generators failed there. A team of first responders in town from Northern California actually helped bring patients to safety.

In a news conference early this morning, Mayor Michael Bloomberg said the city was assured back up power systems at the hospital had been tested.

Mass transit is also a mess. Subway tunnels are flooded in some areas. It's going to be a huge mess to clean up, as the tracks are just littered with debris. MTA officials say trains may not be running for four days, and that all of the salt water will likely cause damage.

Officials shut the Brooklyn Battery Tunnel and the Holland Tunnel down early Monday ahead of the expected floodwaters.

The World Trade Center site is still underwater this morning. Governor Cuomo toured the site in Lower Manhattan hours before it happened.

And, the crane knocked out by the high winds Monday still dangles high above West 57th Street. Surrounding streets are closed as a precaution. No injuries have been reported so far.

Also, the U.S. Stock Exchanges will also be closed again today because of the storm. Trading is expected to resume tomorrow.
