A large power outage left city streets and homes in the dark in Pasadena Monday night.
A Pasadena Water and Power spokeswoman said a couple thousand homes in southeast Pasadena were affected.
Update 8:54 p.m.: PWP: Power will be back within the hour
Pasadena Water and Power says power for the southeast areas of the city will be restored within the hour.
They say they've determined the cause to have been a mylar balloon that got caught in the city's wires.
8:44 p.m.: Pasadena power outage leaves city in the dark
PWP spokeswoman Wendy De Leon said the lights went out at around 7:30 p.m.. Initial reports suggest the outage was caused by a mylar balloon getting tangled in the utility's wires.
"Unfortunately because mylar balloons have metal in them, when they hit our wires, they cause outages. That's why it's really important for people to dispose of their balloons when they're done with them," she said.
"It's one of the leading causes of outages unfortunately," she added.
Pasadena Water and Power says they have crew out investigating the matter and should have the system repaired or an estimate on how long it will take within the next hour.
