Be careful saying things like that, Greg. You might just open Pandora's box of endless debate with a statement like that. I think you're getting at one of the deficiencies of the EF-scale, but I'll refer to other threads on this forum for a further discussion.Looking at all of the video, with so much debris, I was wondering if the EF scale can be "skewed" because of what the storm picks up rather than the wind speeds. In other words, when a tornado like the Tuscaloosa one picks up a lot of debris, it wouldn't require as high a wind speed to do a greater amount of damage than the same tornado going through a less industrious area. It would be easier to level a brick house with flying bricks and steel than it would with flying wood given the same speed. Just wondering if that works into the equation when figuring out storm speed and damage.
