A powerful dust storm swept across Phoenix, Arizona, on Monday, sending a towering wall of sand and debris through the city. The storm darkened the sky, knocked out power for thousands of residents, and disrupted operations at Phoenix Sky Harbor International Airport, one of the nation’s busiest travel hubs.

Local officials reported reduced visibility on highways, prompting safety warnings for drivers. The storm also left scattered damage across parts of the metro area, though no major injuries have yet been confirmed.

Dust storms — known locally as haboobs — are a common occurrence in Arizona’s desert climate, but this event was described as one of the most powerful in recent years. Emergency crews are working to restore power and clear roadways as the region recovers.
