Dust Storms in Arizona Trigger Power Outages and Multi-Day Severe Weather Pattern

Dust storms swept through the Phoenix area and triggered power disruptions for thousands of Salt River Project customers, with approximately 2,500 people losing electricity across multiple locations. The disturbances mark the beginning of a volatile weather pattern expected to persist through the weekend, bringing flash flood risks, severe wind gusts, and additional dust storm activity across Arizona.

Power Disruptions Across the Valley

The dust storm that moved through the Phoenix area on Sunday evening caused two separate outages impacting Salt River Project customers. Around 1,500 customers near Avondale Boulevard and Buckeye Road experienced power loss, with an estimated restoration time near 10 p.m. An additional 1,000 customers east of San Tan Valley were also affected, with weather officially identified as the cause of that outage. Investigations into the other incidents were ongoing as SRP officials assessed damage across the service territory.

Week-Long Storm Pattern Develops

Meteorologists are forecasting a recurring pattern of afternoon and evening thunderstorms extending through Friday, with the most significant activity expected Thursday and Friday. Severe thunderstorms tracked through the Florence and Kearny areas, producing wind gusts of 60 mph, small hail, and heavy rainfall with lightning. Northern Arizona experienced multiple flash flood warnings due to intense precipitation in mountainous terrain. The Valley is expected to see additional storms by 2 p.m. each day, with strong winds, lightning, and blowing dust accompanying each system before dissipating by approximately 10 p.m.

Temperatures will gradually decline as the week progresses, with Valley highs dropping from near-normal levels to the low 100s by week's end. Overnight lows are anticipated to fall into the 80s, while some areas could experience double-digit temperature swings. Flash flooding poses a particular threat to mountain regions where storms are expected to build and track southwest throughout afternoon and evening hours each day.
