In the clean up in New York after Hurricane Irene, the New York Stock Exchange won't delay. A spokesman for the New York Stock Exchange says its building and systems are in working order after the storm passed over the city as a tropical storm. The NYSE will open Monday, as normal, the spokesman said.

The NASDAQ stock and the CME Group, owner of the Chicago Mercantile Exchange and the Chicago Board of Trade, will also open normally on Monday, according to The Associated Press.

New York took a direct hit from Irene but by the time the storm reached lower Manhattan early Sunday morning it was no longer at hurricane strength. Thus, flooding and damage in lower Manhattan, where the NYSE is located, was not as severe as officials feared. 

New York Mayor Michael Bloomberg said he is lifting the city's evacuation order that was in place for the area at 3 p.m. Sunday.

The city's transit system, including a subway system that serves around five million people on weekdays, closed on Saturday and has not yet reopened. Bloomberg has not yet said when transit systems will resume.

If needed, the NYSE could have operated at full capacity using its electronic exchange, the NYSE Arca in Chicago, but that wasn't required.
