Dust Storms
Haboob Weather Explained: Thunderstorm Outflow, Dust Walls, and Desert Wind
What a haboob is, how thunderstorm outflow creates dust walls, and why visibility and air quality can change suddenly.
Quick answer: A haboob is a large dust storm often created by thunderstorm outflow winds spreading across dry ground.
Outflow source
Rain-cooled air rushes out of a thunderstorm and lifts dust from dry surfaces.
The result can be a dramatic wall of dust moving ahead of or away from the storm.
Hazards
Visibility can collapse, air quality can worsen, and gusts can make driving dangerous.
Dust can also affect airports and outdoor events.
Safety
Get indoors or into a vehicle with windows closed when possible.
Drivers should avoid entering a dust wall and pull aside safely if caught.
