Two Tornadoes Strike in NYC
By KAREN MATTHEWS | Associated Press
NEW YORK (AP) Two tornadoes struck New York City on Saturday [Sept 8, 2012], one swept out of the sea and hit a beachfront neighborhood and the second, stronger twister hit moments later, hurling debris in the air, knocking out power and startling residents who once thought of twisters as a Midwestern phenomenon.
Videos taken by bystanders showed a funnel cloud sucking up water, then sand, and then small pieces of buildings, as the first moved through the Breezy Point section of the Rockaway peninsula in Queens.
The second hit west, in the Canarsie section of Brooklyn also near the water, about seven minutes later. The National Weather Service said winds were up to 110 miles per hour, and several homes and trees were damaged.
No serious injuries were reported.
