The Carnival Triumph -- the cruise ship that lost propulsion in the Gulf of Mexico in February, eventually leaving thousands of passengers stranded aboard with backed up toilets and limited food -- broke loose from its moorings at a shipyard in Mobile, Ala.
"Due to strong winds in Mobile, Ala., Carnival Triumph, which was docked at a Mobile shipyard, broke away from its moorings," Carnival said in a statement. "The ship drifted and is currently resting against a cargo vessel. Tug boats and the U.S. Coast Guard are on site."
According to reports, winds reached 70 mph just prior to the incident.
"The windows were shaking like crazy," said Angela Burgin, who, from her window desk on the 21st floor of the RSA building overlooking the Mobile River watched as the Triumph drifted from one bank to the other.
"It was pretty strong for 30 to 45 minutes," Burgin, a financial services administrative assistant, told NBC News.
The ship drifted and struck a moored Army Corps of Engineers boat, the Coast Guard said. No one on that vessel was hurt.
The Triumph suffered a scrape on its side from the collision, and hit a dock as it was drifting, the Coast Guard said.
The Triumph is being controlled by harbor tugs, said Judith Adams of the Alabama Port Authority.
A guard shack two docks over from the Triumph blew over, but was unrelated to the Triumph incident. One person has been pulled from the water and is currently in the hospital. Mobile Fire-Rescue is searching for a second person, still missing.
