Dust Storm Disrupts Phoenix Area Amid Monsoon Activity

A powerful haboob, a massive dust storm, swept through the Phoenix region, causing widespread power outages and travel chaos. The storm, fueled by monsoon thunderstorms, included damaging winds reaching up to 66 mph near East Mesa and led to flight cancellations at Phoenix Sky Harbor International Airport.

The storm’s arrival was preceded by heavy rain and thunderstorms, which resulted in fallen trees and downed power lines. Authorities urged residents to avoid travel until debris could be cleared. Power outages affected thousands of utility customers, while visibility on Interstate 10 dropped to zero, creating dangerous driving conditions.

At the airport, a ground stop was issued for safety reasons, though it has since been lifted. Winds gusted to 60 mph at Sky Harbor and exceeded 66 mph nearby. There was also a report of a roof being torn off a home near Marana.

Outside of the dust storm, thunderstorms continued in Phoenix and Tucson, adding to concerns of flash flooding, especially in canyons and burn-scar areas vulnerable to rapid water accumulation. The Weather Prediction Center has elevated parts of southern Arizona to a Level 2 flash flood risk for Tuesday, as forecasted rainfall rates of 1 to 1.5 inches per hour raise flood fears.

Despite experiencing its second-wettest day of 2025, Phoenix remains in its tenth-driest start to any year on record, with Tucson also recording one of its driest years since 1895. The monsoon’s arrival provides much-needed rainfall for the drought-stricken region.
