What Is That?!!?

Weather has always been a subject of interest to people, even if we still don’t completely have a full grasp of it, not even after all these years and all our technology. The main difference I see now is that we hear about weather all the time. It’s on television, the radio, and even our phones. There are warnings for everything…thunder storms, tornadoes, snow storms, flash floods, and hurricanes. Nevertheless, all the meteorologists can truly do is predict a weather event. It may or may not materialize.

Now, flash back to, oh say 1680 or even to 1521. Other than looking at the sky, how did the people predict the weather? Yes the sky can be a great predictor of coming storms, but unless you knew something about weather patterns, you would be unlikely to have any idea that something like a tornado, flood, or hurricane were coming. Especially in 1680 or 1521. Those dates are rather important in the world of weather. In August of 1521, a meteorological phenomenon occurred in the Basin of Mexico. There were no cameras back them, no cell phones or computers to record the event. The only known description appears in Book XII of the Florentine Codex, which is an account of the Spanish conquest of Mexico written in Nahuatl in the mid-sixteenth century. The account states that just before the fall of Mexico-Tenochtitlan a heavy storm which included a whirlwind struck the basin. The whirlwind hovered for a while above Tlatelolco, Tenochtitlan’s twin city. Then it moved to the lake where it disappeared.

When the experts of today look at the account of the phenomenon in the context of the Nahua culture, and comparing it with European descriptions of tornados and waterspouts, they can determine that the phenomenon was indeed a tornado. Their conclusion is further supported by 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 July 8, 1680, which had been thought to be the first recorded tornado in the Americas, the Tlatelolco tornado actually represents the earliest documented tornado in the Americas. Either way, since people didn’t really have much information to go on back then, I’m sure they first said some version of “What is that?!!?” At least, I know I would have.
