Jokes aside, it’s the first tropical storm to hit Southern California in like 84 years. It’s a category 4 right now off Baja but it’s expected to weaken upon arrival to cooler waters. 8 inches of rain in Palm Springs and 4 inches in Vegas?? Lol that’s a crap load of rain for the desert in August.
The western US needs the water but the landscape isn’t capable of handling that much rain. Flash floods, mudslides and more. Yet another reason to be glad you don’t live there.
