New Yorkers were subject to serious traffic jams on Friday evening as thunderstorms rolled through the city, prompting flash-flood warnings and flight delays in the tri-state area. But social media users were captivated by another side effect of the storms, a bolt of lightning, which struck the spire of One World Trade Center. Witnesses posted photos and video of the spectacular sight on to Twitter and Instagram.
