The storm is expected to hit New York City on Saturday.
While she was promoting her new movie, "I Don't Know How She does It," in New York on Thursday, the 46-year-old Manhattan mom said she is in full storm-preparedness mode.
The actress said she is removing anything that could fly through windows. She's also making sure she and her husband, actor Matthew Broderick; their 2-year-old twins, Loretta and Tabitha; and 8-year-old son, James Wilkie, are stocked up on water, flashlights and batteries.
"I Don't Know How She Does It" is based on the book by Allison Pearson. It is about a career-minded mom juggling a demanding job and the family she adores. It hits theaters Sept. 16.
