LOS ANGELES (CNS) — Scattered power outages blamed on Tropical Storm Kay were affecting thousands of Los Angeles Department of Water and Power customers Saturday, prompting officials to schedule additional field crews to respond to situations throughout the coverage area.

"If you're affected by power outages caused by wind & rain from Tropical Storm Kay, our crews worked through the night and will continue around the clock," the utility tweeted just before 9 a.m. Saturday.

The DWP said the estimated time for crews to respond to an outage is 12 to 24 hours from when it began.

Shortly after 2 p.m., officials tweeted that they'd restored power to approximately 16,000 customers as of Saturday morning, with about 12,795 customers still without electricity.

"The most frequent cause of power outages during heavy rain and wind storms is flying debris, like tree branches and palm fronds, that can make contact with power lines, resulting in outages. This is particularly true with the first rain after an extended period of time, and especially after the dry conditions like the kind the region has seen as a result of the drought," DWP officials said.

The utility urged residents to use caution around downed or dangling power lines or poles. Downed wires should never be touched, and residents who see them should dial 911 immediately.
