UPDATE: Power Restored to 3,500 in Western Malibu

More than 3,500 Southern California Edison customers lost power Saturday in an outage that lasted well into Sunday morning.

The outage began at 7:51 p.m. Saturday along Pacific Coast Highway between Bonsall Drive and Latigo Canyon Road when some trees, likely knocked over due to high winds, came in contact with power lines and caused shortages, according to Caroline Aoyagi of Edison.

Southern California Edison was investigating the cause of the outage. Crews worked to restore power late into the night. Edison estimated power would be restored by 9:30 p.m., but that was later pushed to 12:15 a.m. and then to 7 a.m. Sunday.

By 7:10 a.m. Sunday, only 255 remained without power, but electricity was restored to most by 8 a.m., according to Edison.

"We have restored power to everyone except 11 customers on Bonsall Drive,'' Aoyagi said.

Power was returned to those 11 customers by 1 p.m. Sunday.

Some residents reported seeing a transformer send sparks into the air before the outage began.

A woman named April who lives off Kanan Road said over Twitter that a generator brought to her by Point Dume Pools kept her koi fish alive overnight.

"They made it," April said in a Tweet.
