The whirlwind hovered for a while above Tlatelolco, Tenochtitlan's twin city, before moving to the lake where it disappeared. Analyzing the account in the context of Nahua culture and contrasting it with contemporary European descriptions of tornadoes and waterspouts shows that the described phenomenon was a tornado. This conclusion receives further support from eighteenth-and nineteenth-century pictorial and written evidence showing that tornadoes do occur in the territory now occupied by Mexico City. Since the tornado of Tlatelolco predates the Cambridge, Massachusetts, tornado of 1680, it represents the earliest documented tornado in the Americas.
