I’ve been in quite a few of those AZ gully washers. At one time, we had to detour 70 miles because three bridges were out, one over the Gila River.
And another time, they had to close bridges behind us, as the water levels were right AT the top of the bridges.
Some storms, I just pull over and wait for it to stop raining. I’m glad I’m not there any more.

Been there, done that : )
