New York City, August 15, 2008—The National Weather Service issued a rare tornado warning for the Bronx on Friday as strong thunderstorms rolled over the city.

Residents were initially urged to move to the lower floors of their buildings. Within moments the advisory was downgraded to a severe thunderstorm warning.

Last year a tornado did touch down in Brooklyn, causing damage to buildings. Last week's winds knocked down trees and stalled commuter trains, but didn't spawn any twisters.
