What is a Haboob?
What is a haboob? The short answer is that it is a dust storm or sand storm. "Haboob" is the Arabic word that describes this desert phenomenon. They are most common in the deserts of northern Africa, the Middle East and the desert regions of Australia and North America.
These intense dust storms are the result of cold downdrafts often at the leading edge of a thunderstorm. Their approach can be ominous as an observer will see a wall of orange dust approaching with surprising speed.
There may be a strange quiet calm as the storm approaches, but when it arrives, the calm quickly disappears. First, the winds start and then the dust arrives, whipping around with reckless force.
It is very dangerous to drive during a haboob. The effect is much like fog, limiting the range of visibility. In addition, the strong winds can be too much for a moving vehicle to handle.

If you must be outside during a sand storm, try to keep your nose and mouth covered as you will want to avoid breathing in the dust in the air. It's a good idea to wear glasses to protect your eyes as well.
A haboob may last a few minutes or several hours, depending on its size and speed. It an cause vast amounts of damage because of the wind and the pelting particles of sand that make up the dust storm.
The most common results of a large haboob are fallen trees or broken tree limbs, etching on cars or even glass and thick powdery dust covering the area. The dust can even find its way under doors and through cracks in windows, so you may discover a fine layer of sand inside after a particularly rough sand storm.
