Update on the Cason EF3. It's wind speed estimate has been upped to 155 MPH based on a house that was slabbed. I was confused as to why the description of the homes swept away in Cason mentioned pier foundations, when aerials showed at least one slab foundation home that was swept away. Apparently, that house wasn't added to the DAT until today. The house appears to have been pretty poorly anchored, with apparently some small rusty nails being the only anchoring mechanism. Predictably, they seem to have pulled out and snapped like toothpicks.
