A massive dust storm swept through Arizona on July 13, 2026, knocking out power for thousands and delivering unexpected rainfall totals across the Valley. The storm, part of an active monsoon pattern, collapsed parts of the power grid and left residents grappling with both chaos and an unusual weather anomaly.
The dust storm struck Phoenix around mid-afternoon. Visibility dropped to near zero in some areas. The National Weather Service reported wind gusts exceeding 50 mph. Hazardous driving conditions forced closures on major highways. “It came out of nowhere,” one resident told local media. Fox 10 Phoenix had forecasted storm chances for the week, but the intensity surprised many.
Salt River Project (SRP) reported over 10,000 customers lost power in the Phoenix metro area. Downed power lines and substation damage caused the outages. Restoration crews worked through the night. “We are prioritizing public safety,” an SRP spokesperson said. The utility urged residents to treat all downed lines as live. By morning, power was restored to 70% of affected customers.
The storm also brought rain. ABC15 recorded totals up to 1.5 inches in parts of Scottsdale. Mesa saw 0.8 inches. Central Phoenix received 0.4 inches. The rain mitigated dust but triggered flash flooding in low-lying areas. Mudslides complicated recovery efforts for crews still restoring power. The dual impact—dust then rain—left infrastructure strained.
| Location | Rainfall Total (inches) | Peak Wind Gust (mph) | Power Outages (customers) |
|---|---|---|---|
| Phoenix (Central) | 0.4 | 45 | 3,200 |
| Scottsdale | 1.5 | 52 | 1,800 |
| Mesa | 0.8 | 48 | 2,500 |
| Surprise | 0.6 | 50 | 1,100 |
The Fox 10 Phoenix forecast shows continued storm chances through the week. Lower temperatures are expected, but the active monsoon pattern increases risk of further dust storms and flash floods. Residents still without power should prioritize charging devices and securing loose outdoor items.
The storm exposed vulnerabilities. Dust storms are common, but the combination of power grid failure and surprising rainfall is rare. Climate data suggests monsoon extremes may become more frequent. Preparedness is key. SRP offers outage alerts via its app. Local news stations—Fox 10, AZFamily, and ABC15—provide real-time weather updates.
Arizona’s monsoon season is unpredictable. The July 13 storm delivered chaos, power loss, and an unexpected silver lining of rain. Recovery continues. Residents must stay informed and ready for the next event.
