Tornados cut a narrow swath, compared to a hurricane. I’d wager all the tornados in the last 100 years cause less total economic damage than a single hurricane hitting a coastal city.
Well, I believe that the point is that as tornado alley shifts east that these natural disasters will come closer to larger or perhaps denser metropolitan areas. I do agree with your point. Though, if / as torando alley shifts eastward there could be some significant overlap between the areas that could be impacted by both torandos and hurricanes. I'm reminded of the tornados that hit Alabama last year.
No, even if they hit denser metropolitan areas, they do nothing compared to a hurricane in aggregate damage.
