Triple-digit temperatures expected this weekend in Northern California

The hottest day so far this year is expected to hit the San Francisco Bay Area on Saturday with temperatures soaring into the 90s across much of the region and likely reaching triple-digits in some inland locations, according to the National Weather Service.

Some of the hottest locations Saturday will be in the inland East Bay, where cities such as Antioch, Brentwood and Livermore may flirt with 105 degrees, said Scott Rowe, a meteorologist with the weather service.

The southern areas of the bay won’t be exempt from sizzling temperatures.

Depending where you are in San Jose, temperatures may also reach 100 degrees, Rowe said. Cities along the Highway 101 corridor, including Santa Clara, Sunnyvale and Mountain View, could all reach triple digits.

The weather service has issued a heat advisory.

“If folks are traveling around the Bay Area, remain hydrated,” Rowe said. “Recognize the symptoms of heat exhaustion and help your neighbors.”

Bay Area residents seeking cooler locations should head to the coast, where temperatures will be 25 to 30 degrees cooler. Forecast highs for Saturday include Monterey (73 degrees), Santa Cruz (77) and Half Moon Bay (75).

“It’s a pick your microclimate kind of weekend,” Rowe said.

The soaring temperatures, coupled with low humidity and gusty winds, resulted in the weather service to issue a red-flag warning from Saturday at 11 a.m. through Sunday at 8 p.m. in the North Bay Mountains and East Bay Hills and Diablo Range.

“We’re asking folks to be mindful and not have any open flames during that time because any fires that start could spread rather rapidly,” Rowe said.
