I was working out of our disaster recovery site in Las Vegas yesterday, and while doing some planespotting and listening to ATC at the dedicated parking area next to the runways at McCarran Int'l airport, ATC was notifying a lot of PHX-bound flights that they were being delayed anywhere from 40 minutes to 3.5 hours because of weather in the area. Then I saw this. I was going to start out with defining what a haboob is, but the article would do better than I could, so here's the story, with pics and video to show. Enjoy. https://www.washingtonpost.com/news...evable-photo-of-haboob-sweeping-over-phoenix/ There's video for this as well: BL.
