ABC News' Stephanie Z. Smith reports from Martha's Vineyard:
President Obama will return to Washington, D.C., tonight, one day earlier than originally planned, White House officials said.
The president made the decision to cut short his family vacation on Martha's Vineyard shortly after addressing the nation about the impending danger of Hurricane Irene, which he said has the potential to be "historic."
Obama is expected to arrive back at the White House on Friday evening. His family will remain on the Vineyard through Saturday morning.
The family had been scheduled to return to Washington together tomorrow afternoon.
