The word "haboob" comes from the Arabic word habb, meaning “wind.” A haboob is a wall of dust as a result of a microburst or downburst. The air forced downward is pushed forward by the front of a thunderstorm cell, dragging dust and debris with it, as it travels across the terrain.

Haboobs occur mostly during the summer months in Phoenix, but are not restricted to the monsoon period. These dust storms are much more serious than dust devils. The wind during a haboob is usually up to about 30 mph and dust can rise high into the air as it blows over the Valley. A haboob can last for up to three hours.

I looked up haboob....I've seen pictures like in Iraq, but you get them too??? YIKES!!

This evenings haboob turned out to be minor where I am. They often cause some really bad pile ups on the freeways.

We’ve had some bad ones over the years.
