I've always seen stuff like that...
But my thoughts have always been different (and maybe this is a thing due to living in CO with the mountains)...to me pretty much the last place you'd want to be in a thunderstorm is a creek/ditch/ravine - because thunderstorms have rain (and often heavy rain at that), which means the creek/ditch/ravine could flood & flash-flood at that.
I don't know? Is that not so much an issue out on the plains?
Unless a ditch was already flooded I’d take my chances with any flooding that occurred during the brief period while taking cover from a tornado (which very likely wouldn’t approach a mountain ravine-type event or be life threatening).
