We do. It’s almost always structures like that getting hit that lead to high fatalities, though even then it takes a violent one to usually get there.
With better built structures, like what it appears we have here, it takes an exceptionally violent tornado (High-end EF4 or EF5), to cause similar or worse casualty rates.
Early reports of fatalities here would have indicated to me that we were dealing with a potential EF5 before seeing the actual damage. Since we aren’t, that would tend to suggest high-end EF3 to EF4. Of course, there’s still search and rescue going on, so there’s a distinct possibility that we haven’t learned of some yet...
