Overview
- The storms moved through the Phoenix Valley Tuesday morning and brought isolated thunderstorms, cloud-to-ground lightning and localized rainfall that left roads slick during the commute.
- Firefighters responded to multiple tree and structure fires, including a house near Central Avenue and Camelback Road where smoke was found pouring from the attic and one occupant escaped; Phoenix Fire investigators are examining lightning as a possible cause.
- Utilities reported roughly 3,300 Arizona Public Service customers and about 2,100 Salt River Project customers lost power at the peak of the storm, and most outages were restored by about 10 a.m.
- The Federal Aviation Administration imposed a temporary ground stop at Phoenix Sky Harbor and early-morning operations were delayed, with more than 100 flights affected before the hold was lifted ahead of schedule.
- Maricopa County recorded measurable rain in parts of the Valley and forecasters say the brief storm threat has passed but heat warnings are expected to return for the rest of the week, increasing risk for heat-related impacts.
