There were some pics showed subfloor ripped of the foundation in Washington like this one below.(upper right corner)
I agree that there was a possibility that Washington was one of the strongest tornados but still, lack of high end vehicle damage high end debarking and scouring at the same time in the town lower my confidence.
It is the fact that many violent tornados in this area like Niles 85 or Henryville 12 also didn't produce high end debarking. Neither of them had severe scouring or high end vehicle damage either. It is also true that fast moving tornados are less likely to make high end vehicle damage and trees in this place was harder to debark. BUT, there were fast moving tornados made violent vehicle damage yet most of us still didn't regard it as EF5 tornado like Beauregard. There were tornados completely debark trees in OH alley yet still many people didn't see it as EF5 level tornado like Roanoke(with intense vehicle damage and scouring at the same time). So Washington 2013 tornado was an EF5 level tornado just beacuse the amount of questionable houses it swept away and the amount of debris it granulated is uncertain to me.I can think of a tons of EF4 rating even some EF2-3 rating tornados can make serious debris granulation.just not same amount of Washington made beacuse they didn't hit so many houses.
