Have you ever heard of a Haboob? It is a massive dust/sand storm, and we had one here in Phoenix just the other day….this is video I got off of You tube and it is pretty precise……we came out of a hospital here in the East Valley and were just amazed at what was coming out way! Oddly, we didn’t get much of it at our house, but it was still nasty, my friend Cheri had it hit at her house and she said it went from daylight to dark in seconds! We have had these before here, but this one was 55 miles wide and a mile high!!! Enjoy! This is time lapse photography…….
