LAKE COUNTY, Calif. – Pacific Gas and Electric Co. said late Saturday morning that it is moving forward with a public safety power shutoff that will impact a majority of California’s counties.

The company said it is implementing the shutoff as a safety measure ahead of what is being called a historic wind event that’s forecast to bring dry, hot and windy weather to the region starting Saturday between 6 p.m. and 10 p.m. and continuing through midday Monday.

The number of customers to be impacted by the outage increased on Saturday by 90,000 to a total of 940,000 customer accounts in portions of 36 counties, PG&E said.

The power will be turned off to communities in stages, depending on local timing of the severe wind conditions.

The outage will cover all of Lake County, impacting 37,441 customers, including 2,170 medical baseline customers.

Lake County’s power is expected to go around 4 p.m., as part of the second phase of the shutoff, PG&E said.

However, Sheriff Brian Martin urged people to be ready to have their power turned off up to an hour and a half ahead of the announced time.

PG&E spokeswoman Deanna Contreras separately confirmed to Lake County News that power could go off earlier.

The shutoff will occur in six phases. Times may change depending on weather.

– Phase one, about 2 p.m. Saturday: Amador, Butte, Colusa, El Dorado, Glenn, Nevada, Placer, Plumas, San Joaquin, Sierra, Siskiyou, Shasta, Tehama and Yuba.

– Phase two, about 4 p.m. Saturday: Lake, Marin, Mendocino (south), Napa, Solano, Sonoma and Yolo.

– Phase three, about 5 p.m. Saturday: Alameda, Contra Costa, Monterey, San Benito, San Mateo, Santa Clara, Santa Cruz and Stanislaus.

– Phase four, about 5 p.m. Saturday: Alpine, Calaveras, Mariposa and Tuolumne.

– Phase five, about 5 p.m. Saturday: Humboldt, Mendocino (north) and Trinity.

– Phase six, about 10 a.m. Sunday: Kern County.

Sheriff Martin said Saturday that the forecast weather event is expected to be shorter than anticipated, with the all-clear anticipated on Monday morning, rather than Monday evening.

At that point, PG&E said it will begin inspections in order to restore power.

There will be three community resource centers in Lake County available to provide water, phone charging stations, air-conditioned seating for up to 100 people and restrooms.

PG&E said Konocti Vista Casino, 2755 Mission Rancheria Road in Lakeport, and Twin Pine Casino & Hotel, 22223 Highway 29 in Middletown, will be open from 8 a.m. to 8 p.m. during the outage.

Separately, Clearlake Mayor Russ Cremer said the Clearlake Senior/Community Center will be open and available to residents as a community resource center beginning on Sunday morning. It’s located at 3245 Bowers Ave. Clearlake.
