NORTHERN CALIFORNIA (KTXL) — PG&E said public safety power shutoffs are likely starting Friday and continuing through Sunday in some Northern California counties as wind and dry conditions raise the risk of wildfires.

Some residents in parts of Butte, Colusa, Fresno, Glenn, Kern, Lake, Napa, Sonoma, Stanislaus, Tehama and Yolo counties should be prepared to have their power turned off at some point this weekend, the company said.

According to the PG&E website’s “Public Safety Power Shutoff Forcast”, not every county is expected to experience power outages all three days.

The website also allows users to plug in their addresses to see if their area within the county could be affected.

PG&E said it would be opening outdoor community resource centers with “snacks, water and other essential items” in parking lots in Glenn, Colusa, and Tehama counties on Saturday.

PG&E laid out the mostly limited number of customers it expects could be affected in each county:

  • Butte: 431 customers, 32 Medical Baseline customers
  • Colusa: 559 customers, 37 Medical Baseline customers
  • Fresno: 92 customers, 4 Medical Baseline customers
  • Glenn: 365 customers, 22 Medical Baseline customers
  • Kern: 595 customers, 36 Medical Baseline customers
  • Lake: 86 customers, 3 Medical Baseline customers
  • Napa: 85 customers, 6 Medical Baseline customers
  • San Benito: 2 customers, 0 Medical Baseline customers
  • Shasta: 268 customers, 22 Medical Baseline customers
  • Sonoma: 22 customers, 0 Medical Baseline customers
  • Stanislaus: 29 customers, 0 Medical Baseline customers
  • Tehama: 3,159 customers, 297 Medical Baseline customers
  • Yolo: 99 customers, 2 Medical Baseline customers
  • Other: 5 customers, 0 Medical Baseline customers

PG&E also warned that 49 customers in the Grindstone Rancheria tribal area and 8 customers in the Cortina Rancheria may also be affected.

PG&E said power is shut off to avoid igniting wildfires when strong winds blow debris such as tree branches into contact with power lines.
