Original story:

Pacific Gas & Electric says it has begun turning out the power to 940,000 customers — more than 2.3 million people — across Northern California because of growing winds and extreme fire danger.

The utility said the power shutoff event started taking place around 5 p.m. for the Northern Sierra Foothills and North Bay counties. 

More counties will follow through the night, however, the de-energizing process may take up to two hours once it starts, the utility said. Some shutoffs were adjusted due to real-time weather conditions. According to PG&E spokesperson Brandi Merlo, the utility did this because they wanted to impact as few customers as possible.

Here's when and where the shut offs will take place:

  • 5 p.m. - Amador, Butte, El Dorado, Glenn, Nevada, Placer, Plumas, San Joaquin, Sierra, Shasta, Tehama, Yuba, Colusa, Solano, Marin, Sonoma, Mendocino (south), Yolo
  • 8 p.m. - Alameda, Contra Costa, Monterey, San Benito, San Mateo, Santa Clara, Santa Cruz, Stanislaus
  • 9 p.m. - Humboldt, Lake, Mendocino (north), Siskiyou, Trinity
  • 12 a.m., Oct. 27 - Alpine, Calaveras, Mariposa, Tuolumne
  • 9 p.m. Oct. 27 - Kern

It's the latest preventative shut-off amid concern that gusty winds could knock out power equipment and spark fires.

Forecasters say the encroaching wind event will peak early Sunday and be among the strongest in years.

The two previous shutdowns were done amid concern that gusty winds could foul or knock down power lines and spark devastating wildfires.

PG&E's warning came as firefighters battled flames in Northern and Southern California.

Some 50,000 people under new evacuation orders are fleeing Sonoma County communities near a huge wildfire that will be stoked by the new round of winds.
