On 25 August, a massive dust storm, known as a haboob, struck the Phoenix metropolitan area, starting at around 1630 hours local time. Haboobs, associated with collapsing thunderstorms, can make driving impossible, and this storm cut visibility to a quarter-mile. With wind gusts up to 70 mph, the storm caused power outages for over 60,000 people and significant travel disruptions, including a ground stop at Phoenix Sky Harbour International Airport. While the storm cleared by the evening, it highlights the vulnerability of critical infrastructure to increasingly severe weather, posing ongoing security and operational challenges.
