IDK...there should be something that provides stronger value into potential like today. Not that flash flood watches are super common here but they aren't super rare either. I guess the question that comes down to is, how does the general public typically respond to something like a flash flood watch? Maybe those who live in flood prone areas may take it with some seriousness but my wager is most people probably do nothing or don't even pay attention.
In a potential like this...there should be something highlighting the greater potential.
