Couple thing to remember, one is that thankfully there is much less population once you get west of OKC, certainly compared to say Alabama. Of course if only takes one storm in a bad spot to make for a very bad day. Second, As I mentioned in the other thead, very important for people to not seek shelter in a low lying area with the high flood risk. There were 13 flooding deaths in OKC metro during the El Reno event.
