BOROUGHWIDE — A flash storm with extreme winds hit Brooklyn Friday night, breaking grown trees in half, damaging cars and swirling debris into the sky.

“It looked like a mini-tornado,” said a resident of the Whitman Owner tower on Henry Street in Brooklyn Heights, describing tree branches swirling outside their 23rd-story windows. Hannah, a Clinton Street resident, said she saw construction materials flying in the air.

Numerous Brooklyn Heights residents said their power blinked just as the storm hit. According to NBC, wind gusts hit 80 mph.

On Saturday morning, the sound of wood chippers could be heard across Brooklyn, and car owners were out early taking photos of their damaged vehicles for insurance claims.

Large tree trunks fell across Pierrepont, Remsen, Clinton and Joralemon streets in Brooklyn Heights. A Parks Department employee told the Brooklyn Eagle that the area had experienced a “microburst.”

According to the National Weather Service,  a microburst is a sudden, highly concentrated downdraft of sinking air within a thunderstorm. When the cool air hits the ground, it produces intense, damaging winds that can exceed 100 mph.

The strong winds also took down some of the grandstands on Governors Island, which had been set up for the Parade of Sail event. The $200 Premier Access viewing area was so damaged by the storm that it had to be closed, according to event organizer Sail4th.

“After assessing the site, we have made the difficult decision to cancel Premier Access viewing … in the interest of the safety of our guests and staff,” Sail4th said in a release. The organization said it was working on refunds.
