At least eight people were killed Thursday night when a tourist boat capsized in a southern Missouri lake as powerful thunderstorms passed through the Midwest, the authorities said.
The amphibious boat, or duck boat, overturned in Table Rock Lake near Branson, Mo., around 7 p.m. as winds exceeded 60 m.p.h.
Sheriff Doug Rader of Stone County said the duck boat sank to the bottom of the lake, and that seven passengers were taken to a hospital. Divers were searching for missing passengers, and the sheriff said that would continue overnight.
A sheriff’s deputy was among those on the boat when it capsized and was assisting in the rescue, he said.
The boat capsized because of severe weather, Sheriff Rader said, adding that he believed that all the fatalities were caused by drowning.
The Southern Stone County Fire Protection District said on Facebook that 20 or more people were on the boat.
Ripley Entertainment owns the boat, having acquired the Ride the Ducks attraction in Branson last year. Duck boats can float on the water and drive on land.
Suzanne Smagala-Potts, a spokeswoman for Ripley Entertainment, said this is the first time an accident had happened at this location. “Our thoughts are first and foremost with the families,” she said.
Family members of missing people believed to have been on the duck boat were directed to go to Branson City Hall.
The episode was the result of a storm system that meteorologists said passed across much of the Midwest on Thursday.
Steve Lindenberg, a meteorologist at the National Weather Service’s office in Springfield, Mo., about 45 miles north of Branson, said “a line of thunderstorms” rattled both areas on Thursday night and produced winds of up to 74 m.p.h. The winds downed trees and power lines, he said.
Mr. Lindenberg said a 63-mile-per-hour wind gust was recorded at Branson’s airport around 6:55 p.m. local time, though he did not know whether the winds had caused the boat to capsize.
He said the thunderstorms had since left Missouri and were moving into Arkansas.
