First responders searched overnight for a person in the water in or around Rhode Island's Narragansett Bay Monday night, officials said.
A woman fell off the Prudence Island ferry about 6:30 p.m., Bristol's fire chief told NBC affiliate WJAR.
But the search was suspended Tuesday, after Coast Guard crews spent 10 hours scanning 39 square nautical miles without finding her, officials said.
Coast Guard staff from Newport, Rhode Island, and Cape Cod were involved in the search, along with the Narragansett Bay Marine Task Force, according to a Coast Guard tweet.
One cutter went out searching overnight and a second was scheduled to join at first light. It was unclear how the woman fell overboard and if she was wearing a lifejacket.
The water temperature at the Conimicut Light, inside the bay, was about 48 degrees Monday night, according to a NOAA reading.
