The actress, who plays Alice Cullen in the Twilight saga, was due to join fellow stars Robert Pattinson, Kristen Stewart, and Taylor Lautner at a press event in Los Angeles.
Greene's flight from New York to LA was cancelled, however, due to a new storm that has emerged on the East Coast.
The 25-year-old posted on Twitter after the flight was postponed, writing: "Stranded in NYC missing the last Twilight press junket… Much love to the cast & press there supporting the film – wish I could be there!
"Can't believe it up and started snowing in NYC and that the flights are cancelled AGAIN nyc I Love You but LA I Miss You." (sic)
The storm comes just days after Hurricane Sandy wreaked havoc on the East Coast, prompting several fundraisers and charity events in the entertainment world.
Greene and her Breaking Dawn Part 2 co-stars will be reunited on the big screen when the film opens on November 16.
