Thousands without power in Riverside

Heavy winds and rains knocked down power lines in Riverside, leaving 10,000 people without power Friday night, according to Riverside Public Utilities. 

As of 6:40 p.m., power had been restored to the majority of those affected, but 1,500 residents remained in the dark. 

Officials warned people to stay away from downed power lines and to call 911 when they come across them.

High surf expected along southwest California beaches

High surf will pound most southwest California beaches through the weekend, according to the National Weather Service.

A long swell will move through the area Sunday night and Monday, bringing another round of high surf and powerful rip currents.

Rip currents form at breaks in sand bars and near jetties and piers, according to the National Weather Service.

The strong currents, with an average speed of 1 to 2 feet per second, flow away from the shore at surf beaches. Some currents can move as fast as 8 feet per second, which the weather service says is faster than an Olympic swimmer.

Forecasters advise beachgoers to enter the ocean only if lifeguards are present. If you are caught in a rip current, remain calm. Lifeguards and forecasters says it’s best to relax and float to conserve energy.

Don’t fight the current and do not swim directly toward the shore. Swimmers should paddle parallel to the shoreline to break away from the current’s pull. After escaping the current, swim at an angle away from the current and then toward the shore.

A California Department of Transportation crew had a close call Friday when its dump truck was nearly thrown off the edge of a Mendocino County highway by a rockslide that rushed toward them.

The crew arrived at the site of the slide, on Highway 1 about five miles north of Westport near Fort Bragg, about 3 a.m. to set up traffic control lights so they could see the rocks in the dark, according to Caltrans District 1 officials.

As a worker sat inside the dump truck near the slide, a second rockslide came down. The force of the slide pushed the truck onto its side.

“Thankfully the truck was not pushed over the edge of the highway, it was stopped by a guardrail, and the employee was not injured, only shaken up,” Caltrans wrote on Facebook.
