Haboobs are usually caused by collapsing thunderstorms which cause gusts of wind to travel out from the area of precipitation and downward towards the ground.
When these down draughts hit the dry, loose sand of desert regions like Arizona they blow up large volumes of dust which then travel as a cloud or wall of sediment.
The sandstorm captured in these videos is the first major haboob of the monsoon season which usually runs from June to September.
