David Letterman and Jimmy Fallon shared the mindset that the show must go on even in the face of Sandy storming outside.

Harsh winds and severe flooding caused low-lying areas to be evacuated in New York City. Other residents of the metropolis were told to stay put and wait out the storm indoors.

Even with the public busy bracing against the storm, the two talk show hosts taped their programs this afternoon without audiences.

Late Show host David Letterman began his monologue: "We're in the middle of Hurricane Sandy and we have no studio audience, but we do have quite a show for you tonight. Thank you for joining us in the Ed Sullivan Shelter."

Letterman talked with band leader Paul Schaffer mentioning that New York expected 90 mph winds and around a foot of rainfall saying Sandy is "one of the worst storms in U.S. history." He continued, "If I were home, I'd be boarding up your television sets, because this is the stuff that's gonna hurt somebody."

The Late Show host did the Top 10 Rejected Names for the Storm which includes Trumpical Storm,, Al Frankenstorm and Oprah Windy.

Denzel Washington appeared on the show wearing a yellow rain jacked promoting his latest film "Flight."

Washington who joked he "swam" to get to the show.

Late Night host Jimmy Fallon had his own audience free fun by opening his show outside the studio at 30 Rockefeller Plaza.

"I'm hoping, if you're watching, you are at home, you're safe, you're warm...but we're here," opened Fallon.

"Theater owners had to cancel all Broadway shows today," Fallon said in his monologue which panned to the empty theater. "Many performers were having trouble making it into the city. You could tell by that one show, Blue Man Guy."

The Late Night host welcomed a full line up of guest that included Seth Meyers, Padma Lakshmi, Robert Zemeckis and ended with a performance by Imagine Dragons.
