Patricia’s supposed 320 km/h wind speed over the ocean was not actually measured. It was merely predicted by computer models based on the measured speeds thousands of feet above the surface. The evidence that it was exaggerated is the rapidity with which the winds supposedly diminished after the storm reached land, where it could be measured.
