The National Weather Service published a report on the severe dust storm.
"According to the American Meteorological Society’s Glossary of Meteorology, blowing dust/dirt
events with minimum visibilities of 0.63 miles or less are indicated as a 'dust storm,' with minimum visibilities below 0.31 miles indicated as 'severe dust storm.' Severe dust storms associated with a wall of dust and a rapid onset of reduced visibilities and gusty winds are
sometimes caused by thunderstorm outflows or frontal passages, such as what was observed on 16 May (Figure 1). In these situations, the dust storm is often referred to as a 'haboob,' based upon the Arabic word for 'to blow.' Severe dust storms or haboobs are uncommon in the Midwest, and much more frequently observed in the Desert Southwest and Great Plains of the United States or in arid regions of the Middle East, Sahara Desert, or Central Australia
(American Meteorological Society, 2025)."
