The first time I got the alert (non-amber) it took me by surprise. Having never seen/heard of it I thought it was mistake/joke. It was a flash flood alert in Las Vegas, a desert. It happened again the following day but this time a friend shared with me a pic of a flooded Caeser's Palace casino. It helped me avoid that area.
