Everything that I thought I knew about violent tornadoes and death tolls has gone out the window this spring. It's been a long time since we've seen these kinds of death tolls, and I (like many others I imagine) was lulled into this idea that we wouldn't see this again. I've heard various sentiments in the past few weeks to the effect of "if you get a violent tornado going through a densely populated area, deaths are inevitable". While that may have some truth to it, I cannot help but feel that this is an insufficient answer. Like you Josh, I'm wondering how this happened, given how many violent tornadoes have rolled through significant population centers in the past few decades. Why weren't the Moore-OKC (1999) or Pleasant Grove (1998) tornadoes more deadly, for example?
