Sizzling temperatures continued to bake some California cities July 5 and could stick around for another week in the central region of the state, according to the National Weather Service.

“It’s going to be hot. There’s no doubt about it,” National Weather Service Meteorologist Carol Smith at the Oxnard office in Los Angeles County told The Epoch Times.

The weather service issued excessive heat warnings during the ongoing heat wave for Los Angeles basin, which includes the cities of Los Angeles, Santa Monica, Beverly Hills, Lucerne Valley, Pasadena, and West Hollywood.

Santa Clarita, about 30 miles north of Los Angeles, was expected to reach 118, Ms. Smith said.

Saturday could bring a little warmer temperatures to in some parts of the Southern California region, including Antelope Valley and Santa Clarita.

The region should start to see some cooling starting Sunday, with temperatures ranging from 85 to 100, according to the weather service.

With the high temperatures, officials warned the public to stay cool and hydrated.

“There’s a high risk for heat-related illnesses for pretty much anyone,” Ms. Smith said. “It isn’t a time to take your dog hiking. You might not want to go hiking yourself.”

The Sacramento Valley will remain under a dangerous, long-duration heat warning issued by the National Weather Service, until July 9.

Temperatures in the valley, the Sacramento Delta and Sierra Nevada foothills are expected to range between 100 and 118 degrees, while mountain temperatures will be between 95 and 110 degrees.

In the San Francisco Bay Area, the National Weather Service expects sizzling daytime temperatures above 100 through July 12.

Hot conditions in the region could cause life-threatening impacts and affect commerce and travel, according to an excessive heat warning issued by the National Weather Service.

All areas except the coastline in the Bay Area are covered by the heat advisory, which calls for temperatures ranging from the mid-90s to 110 degrees.

Further south in San Diego County and the desert region of Palm Springs and Palm Desert, weather forecasters are looking at highs reaching 125 degrees in some areas.

Palm Springs residents were baking under a high of 121 degrees Friday, while other inland cities, including El Centro on the Mexican border, were expected to reach 117 degrees.

San Diego was set to see a high of 78 on Saturday. A cooler Sunday could follow with high temperatures in San Diego reaching 76 degrees, according to the weather service.

Temperatures in the San Diego region could stay relatively the same on Saturday while easing off just a couple of degrees on Sunday.

Gov. Gavin Newsom activated the state’s emergency services operation center ahead of this week’s heat wave and urged Californians to take extra precautions.

“This heatwave is serious,” Mr. Newsom said in a statement released July 1. “We’re used to hot temperatures in California but this will be several days with little relief overnight.”

The governor directed emergency services to activate its “extreme temperature response plan,” which is triggered by National Weather Service predictions of excessive heat. The activation moves the state into a coordinated all-hands response by state government.

The state reached out to a network of community organizations to ensure Californians had access to cooling centers and other resource, and enforced heat protections for outdoor workers, according to the governor’s office.

Since 2005, California has enforced outdoor heat rules requiring companies to provide shade, water, and rest when temperatures exceed 95 degrees.
