MORENO VALLEY (CBS) — About 150 households in Moreno Valley remained without electricity Wedneday after several power lines were knocked down.

Power lines fell onto several homes about 3:30 p.m. Tuesday on Filaree and Patricia avenues, according to a spokesperson from Southern California Edison.

People were ordered to stay inside while crews shut off the flow of electricity, and about 2,500 customers were temporarily without service.

Power lines fell in a “T” shape over several homes, Riverside County Fire Department spokeswoman Jody Hagemann said. The area from Kitching Street to Filaree and Perris Boulevard to Gentian Avenue was temporarily blacked out, with service restored to most homes by 5 p.m., Edison spokesman Danny Chung said.

Some emergency personnel at the scene said a Mylar balloon was sparking between two electrified wires.

Chung said residents should stay away from downed lines and call 911 to report them.
