A man jumped off of a cruise ship as it headed towards Puerto Rico on Saturday. Now the Coast Guard is on the search for the man who went overboard.

Tien Phuoc Nguyen, 26, was on Royal Caribbean's Adventure of the Seas with his family. The ship was in Mona Passage and was heading toward San Juan, Puerto Rico when a passenger told the captain that they saw another passenger go overboard. The captain turned the ship right around and called authorities, ABC reports.

Nguyen, from Canada, was seen jumping off the ship at around 8:46 p.m. on Saturday. A Royal Caribbean spokesman said that closed-circuit cameras on the ship caught the man jumping off the ship.

When the Coast Guard was notified, an Air Station Borinquen MH-65 Dolphin helicopter was sent out to perform a search as well as a USCG Cutter Cushing.
"We will continue to search until we determine that all probability of survival has been extended," Coast Guard spokesman Ricardo Castrodad said according to ABC.

Castrodad said the searchers were still hopeful about finding Nguyen alive but he also said the weather around the Mona Passage and the water can often be unpredictable and dangerous.

"Weather conditions there typically change rapidly. It could be a good weather day and a weather system comes in and everything turns and becomes pretty nasty," Castrodad told ABC.

"You can have easily from two to four feet seas and then be facing 10-foot seas from one moment to another, so it is known as a pretty dangerous body of water," he said.

As the Coast Guard continues on their search, the FBI is also investigation what may have caused Nguyen to jump off the ship.

The Adventure of the Seas cruise ship continued on to the port when the Coast Guard took over the search. The ship was returning on Saturday after a week-long trip that made several stops in the Caribbean.
