Weird how people are fired up over the watch issuance thing - all it does is let me know that if the area I am in has a storm set up over it, I need to be cautious when travelling out and about over the possibility of high water. That's helpful as hell, to distinguish the danger of heightened localized flooding chances from any given pop up storm in this set-up versus other times when you don't need to worry as much about that from pop up storms.
I know it was nice to have that tucked in the back of my head as I drove in the deluge last night - I was cautious as hell approaching low spots in the road near creeks to make sure that there was not pooling water in those areas.
