Those storms are SCARY! I've been in one, and that's all I need, thank very much!
My brother and I had to wait one out in a Ladies room in CA City, CA, and when it finally blew itself out, we played the devil getting out! The sand was nearly 6 inches deep outside that door! My mother and 2 youngest brothers threw blankets over the car, and Dad and Grandpa took shelter in, of a places, a port a potty! Was hiding from that strorm for a LONG time. I NEVER want to see that again!
