1.8 inchs of rain in just about an hour or two. Wham! It was awesome! You have to know where to be when a flash flood episode hits Vegas, more important, where not to be. Millions of dollars of flood control work have not yet cured Vegas's flash flood problems. I remember whole neighborhoods going down. A lot that has been fixed. Unlees you've lived here a while, you won't have any idea what's about to happen when it starts pouring across the whole Valley. I've nearly been swamped more than once for ignoring the signs.
