OTD 15 years ago, a strong tornado outbreak occurred in the state of Arizona. While the strongest of them was an official high-end EF3 that occurred near Tuba City, one of the weaker Bellemont twisters had unofficially intensified to mid-EF4 strength as it passed over a burn scar that contained an anemometer that recorded a peak windspeed of 185 mph. However, there was nothing in the burn scar that could confirm the measurement, so the anemometer was promptly ignored during the survey. To this day, the 2010 East Bellemont Tornado is unofficially the strongest tornado to ever be observed in the desert southwest; however, there was no further evidence to prove it was, except for the anemometer.
