Haboobs, Saharan dust plumes, sandstorms, and air quality impacts worldwide
This dust storm monitor tracks active dust and sand events worldwide, from continental-scale Saharan plumes that reach the Caribbean and Americas to localized haboobs over arid regions. Users searching for dust storm near me, Saharan dust forecast, or sandstorm map can see active events and air quality impacts.
Haboobs are intense, short-lived dust walls produced by thunderstorm outflow winds in arid regions. They typically advance at 50–100 km/h and can rise over 1,500 metres, blanketing cities like Phoenix and Khartoum in minutes. Synoptic-scale dust storms form when large pressure gradients drive sustained winds across desert source regions, producing plumes that can travel thousands of kilometres and persist for days.
The Sahara emits more dust than any other source globally — over a billion tonnes annually. Saharan dust regularly crosses the Atlantic to reach the Caribbean and southern US during summer, suppressing Atlantic hurricane formation through stable dry air. Saharan dust deposition is essential to fertilizing the Amazon rainforest, while the same dust degrades air quality across affected regions.
Dust storms produce high concentrations of fine particulate matter (PM10 and PM2.5) that penetrate deep into airways. Exposure causes acute respiratory irritation, asthma attacks, and increased cardiovascular events. People with chronic respiratory and cardiac conditions face elevated mortality risk. Mineral dust also carries microorganisms and chemical contaminants picked up from source regions, contributing to valley fever and other infectious diseases.
Dust storms ground aircraft, abrade jet engine components, and clog air filters. Visibility can drop below 100 metres during peak haboob conditions, suspending highway traffic and closing airports. Solar power generation drops sharply during dust events as airborne particles attenuate sunlight and accumulate on panels. Wind erosion during severe dust storms degrades agricultural soils and damages crops.
