A woman who is believed to have fallen overboard from a cruise ship off Florida Sunday night is still missing, and U.S. Coast Guard crews are combing the Atlantic for her, officials told NBC News Tuesday.
The 21-year-old?woman, who is from Bartlett, Tenn., was on a Royal Caribbean Allure of the Seas ship 47 miles east of Fort Lauderdale when she reportedly fell into the ocean.
Crew members searched the cruise ship Sunday night for the woman; when they couldn't find her, the captain alerted search-and-rescue officials at the Coast Guard in Miami.
Florida's Sun Sentinel reported a fellow Allure of the Seas passenger saw the woman go overboard around 9:25 p.m. Sunday;?the ship's camera footage later confirmed she had gone into the water, Royal Caribbean told the paper.?
A call from NBC News to Royal Caribbean was not immediately returned.?
As of Monday, the Coast Guard's search area spanned approximately 320 square miles. In addition to searching by boat, the Coast Guard used four aircraft, but the woman -- whose identity was not made public -- was not found.
A Coast Guard spokesman provided no additional details, including any information on the cause of the woman's fall.
Allure of the Seas has been in service since December of 2010 and has a capacity for 5400 guests, according to Royal Caribbean's website.
