The Big Board is ready to open for trading Monday.
A spokesman for the New York Stock Exchange says its building and systems are all in working order after the worst of Tropical Storm Irene passed New York.
But the exchange was awaiting word from the Securities and Exchange Commission before making a final decision on whether to open.
The question Sunday was whether workers will be able to get to downtown Manhattan.
Mayor Michael Bloomberg shut down the city's transit system ahead of the storm. It was not clear whether subways and trains would be running before Monday afternoon.
The flooding and damage in downtown Manhattan Sunday afternoon were not as severe as officials had feared. The area had been evacuated Saturday.
