• Dust storm — the general phenomenon: strong winds lift dust and sand, cutting visibility. NWS issues a Dust Storm Warning when blowing dust drops visibility to ¼ mile or less (winds are usually ≥ 25 mph).

• Haboob — a specific type of dust storm driven by thunderstorm outflow (gust front/downburst) that creates a fast-moving “wall” of dust, most common in the Southwest U.S.

Bottom line: All haboobs are dust storms, but not all dust storms are haboobs—the term “haboob” refers to the thunderstorm-outflow origin; “dust storm” is the broader hazard category used in NWS warnings and safety messaging. THANK YOU FOR YOUR ATTENTION TO THIS MATTER #Arizona #Haboob
