Phoenix Hits Category 5 Dust Storm | Tucson News

Phoenix just endured its second Category 5 dust storm this season — a rare and record-breaking event that blanketed the city in a wall of dust driven by powerful thunderstorm winds. Dust levels soared past 5,800 micrograms per cubic meter in west Chandler, with gusts hitting 25+ mph for hours. Developed by Arizona State University, the PHX Dust Storm Scale rates these events from one to five, with Category 5 meaning you’re breathing in over a million microscopic dust particles per hour — each finer than a human hair strand. This isn’t just a nuisance; it’s a serious health and visibility threat, reminding us how extreme weather can strike even in places we thought were immune.
