From the story:
“It looked like tornado activity, a very dense black wall, almost like a heavy velvet fog,” said J. R. Thomason, a fundraiser for the NY Philharmonic, who watched the storm from an attic room in a three-story house in the Kensington district of Brooklyn between 6 and 7 a.m.
John Han, 50, a financial adviser, said he arrived at the Fort Hamilton stop at around 7:45 a.m., but about an hour later had given up and was going home.
At 370 East Second St. in Kensington, Carol Perri DeSimone, a sales representative, stood amid the remains of her porch. “I’m heartbroken, my roof landed three doors away,” she said. “I was scared to death.”
