When this downdraft, or “downburst”, reaches the ground, dry, loose sand from the desert settings is essentially blown up, creating a wall of sediment preceding the storm cloud. This wall of sand can be up to 100 km (60 miles) wide and several kilometers in elevation. At their strongest, haboob winds can often travel at 35–50 km/h (20–30 mph), and they may approach with little to no warning.
