Massive blackout felt across YumaPosted: Updated:
YUMA, Ariz. -- A massive power outage left millions without electricity in Yuma, San Diego and Mexico. By Thursday night, Arizona Public Service said they were able to restore power to everyone in Arizona.
The blackout began just after 3:30 p.m. Thursday when a transmission line near Yuma tripped off-line.
Officials with APS say it was likely related to a procedure an APS employee was carrying out in the North Gila Substation, northeast of Yuma.
The agency is still investigating what caused the outage to spread beyond the Yuma area.
The blackout happened as Yuma was in the midst of an extreme heat warning, with temperatures hovering above 110 degrees.
Jessica Tuggle said when she got home from work the temperature inside her home had reached 95 degrees.
Tuggle was at work when she said all of a sudden the computers and lights flickered and went off.
"On the drive home all the stoplights were out," Tuggle said. "There was a lot of traffic. It was chaotic."
The city of Yuma said Thursday night several local school districts were canceling classes for Friday. Those districts are Yuma Union High School District, Yuma Elementary District 1, Crane Elementary DIstrict, Somerton Elementary District and AmeriSchools Academy Campuses.
Yuma city spokesman Dave Nash said parents should check for updates with their individual schools in the morning.
