Interesting. Thanks. Looking at the horizontal and vertical scales there don't seem to be any steep bits at all, though short steep bits might not show up on that, I'm not sure. A few cursuses terminating at a steep slope might tell a tale, because the tornado wouldn't have.

I was interested that the recent Birmingham tornado touched down again a few miles later, still on the same line, so "aligned cursuses" would be interesting. Are we getting towards ley lines here? (Hope not!)
