Overview

• Near-zero visibility prompted Dust Storm and Severe Thunderstorm Warnings as NWS and ADOT urged drivers to “Pull Aside, Stay Alive.”
• Power outages peaked in the tens of thousands — with some tallies above 50,000 statewide — and thousands were still without electricity by Tuesday morning as crews worked repairs.
• Phoenix Sky Harbor imposed a roughly hourlong ground stop, more than 40 flights diverted, and delays persisted into the night before operations stabilized.
• Airport officials reported wind damage with roof leaks in passenger areas and ongoing cleanup, while police and residents noted downed trees and traffic-signal failures in parts of the metro area.
• The wall of dust formed near Eloy/Arizona City and raced into the Valley; forecasters kept limited storm chances through Tuesday before a trend toward drier conditions later this week.
