LOS ANGELES, United States (AFP) — A severe storm pounding southern and central California reportedly killed at least four people overnight Friday, causing flash floods and forcing the evacuation of hundreds of people from their homes.

Los Angeles (LA) city fire officials said a 55-year-old man was electrocuted after a tree downed a power line. Several people stranded near the Los Angeles River had to be rescued with inflatable boats.

Two other people died in car accidents in the San Diego area, and a fourth died in a submerged vehicle, local media reported.

Another person was injured after her car fell into a massive sinkhole in Los Angeles, local television station KABC reported. She was trapped until fire crews pulled her out.

The powerful storm blew in from the Pacific Ocean, hitting California on Friday with high winds and heavy rain that downed power lines, leaving 60,000 people in the Los Angeles area without power, and prompting hundreds of flight delays and cancellations at airports.

Rushing floodwaters swept away cars, downed trees and caused mudslides and sinkholes, the National Weather Service (NWS) said.

Flash flood warnings will continue through the weekend in many areas of the west coast state, which has been hit this winter by a series of storms that have filled reservoirs, bringing respite following a severe five-year drought.

Although the latest storm, which packed heavy, wind-driven rain, was mainly affecting southern and central California, rain was also forecast to hit the San Francisco Bay Area in the north.

Residents of the city of Duarte, located in the foothills of the San Gabriel Mountains east of Los Angeles, were ordered to evacuate on Friday for fear of mudslides, and voluntary evacuation orders were issued for some residents of Camarillo Springs, north of LA.

“The storm looks to be the strongest to hit south-west California this season,” the NWS in Los Angeles said.

The weather service said the northern part of the state — where flooding last week damaged the lake Oroville Dam and forced the evacuation of nearly 200,000 people — was expected to see new rain and snow systems moving in during the next few days.

It forecast “the wettest storm” on Monday and Tuesday, warning of possible renewed flooding across northern California.

“Recent storms have left the region highly vulnerable, so amplified impacts will be possible with additional rainfall,” the NWS said.
