A line of intense storms moved southeast across the WFAA viewing area Sunday evening, toppling trees, damaging homes and businesses, and leaving thousands without power.
At Eagle Mountain Lake, a part of Lake Country Marina became detached and started floating away — with 30 large boats moored to it.
Randall Johnson told News 8 he took cover inside his boat and waited for the storm to pass.
"I was talking to my girlfriend on the phone. Next thing you know, sheet metal started flying, and I hollered at her, 'The dock's breaking up!'" Johnson said. "It was five minutes later, 10 minutes later when it finally calmed down and I looked outside, and we weren't even where we were supposed to be at... we were over by the land."
The detached "I Dock" ended up about 500 feet away from the marina. About 10 people on the floating dock or aboard their boats had to be rescued.
Witnesses said they were stunned by the sudden wind they estimated at up to 80 mph.
"Tables were flying; chairs were going into the water," said Mike Pfleger, who runs the karaoke show at Scampi's Cove restaurant. "The next thing you know you see the whole I Dock roof just cave down and you see it just drifting away slowly."
The dock ended up about 500 feet away from the marina.
No injuries were reported, but more than two dozen boats were damaged.
About 15 aircraft were damaged at Meacham Airport in Fort Worth, including a 1965 vintage jet training aircraft originally developed for the Soviet air force. No injuries were reported.
In Denton County, high wind ripped the roof off at least one home and several barns near Krum. Fences were toppled and power was out in the area.
Wind gusts up to 76 mph were reported near Keller in Tarrant County, and the National Weather Service office in Fort Worth recorded a 73 mph wind.
Just before 10 p.m., Oncor reported nearly 50,000 homes without power across Tarrant County, concentrated in Fort Worth, Haltom City and Lake Worth.
The weather service said 80 mph winds were reported near Venus and there was damage reported along the Johnson-Ellis county line, with the strong wind headed in the direction of Maypearl.
