The National Weather Service has determined that two tornadoes ripped through New York City during a fast-moving storm, along with a fierce macroburst with wind speeds up to 125 miles per hour.
Authorities made the ruling Friday after examining the path of the storm and the damage left in its wake.
Officials said the tornadoes left a path of destruction for 14 miles from Brooklyn to Queens. One person was killed.
The National Weather Service had initially reported that a microburst hit the city. Officials later corrected themselves to say it was a macroburst, because it was more than 2 1/2-miles long. Thursday's macroburst was 8 miles long.
The city estimates more than 1,000 trees were destroyed and dozens of buildings damaged.
They are the ninth and tenth tornadoes to hit New York City since 1950.
