Pacific Gas and Electric Company (PG&E) meteorologists are monitoring a potential weather system that could bring dry, gusty offshore winds to portions of the Northern, Central and Southern regions of the company’s service area beginning Monday morning.
Given this offshore wind event, combined with extreme to exceptional drought and extremely dry vegetation, PG&E is sending two-day advance notifications to approximately 44,000 customers in targeted portions of 32 counties and seven tribes where PG&E may need to implement a Public Safety Power Shutoff (PSPS) to reduce the risk of wildfire from energized power lines. Many counties will only have small portions of expected outages, some fewer than 100 customers.
Despite the potential for rain in some areas this weekend, PG&E is notifying customers of the possible PSPS in case rain doesn’t materialize or forecasted wind speeds still pose a wildfire risk. The potential shutoffs could begin Monday morning in portions of the North Valley, Sacramento, and San Joaquin Foothills. Potential shutoffs for the Northern Sierra Foothills, North Bay, North Coast regions, Bay Area hills and the Central Valley could begin Monday evening, depending on the timing of the wind event.
PG&E activated its Emergency Operations Center on Friday to support this weather event.
Customer notifications via text, email and automated phone call began Saturday, approximately two days prior to the potential shutoff. Customers can also look up their address online to find out if their location is being monitored for the potential safety shutoff at pge.com/pspsupdates.
During a PSPS, PG&E offers support to customers by opening Community Resource Centers with snacks, water and other essential items, partnering with community-based organizations to assist customers with medical and independent living needs; and continuing to update our customers on power restoration status.

With the potential PSPS two days away, conditions may change. PG&E’s in-house meteorologists, as well as its Wildfire Safety Operations Center and Emergency Operations Center, continue to closely monitor conditions. PG&E will share additional customer notifications as conditions evolve.
Public Safety Power Shutoffs: What PG&E Customers Should Know
Why PG&E Calls a PSPS Outage
PG&E initiates PSPS when the weather forecast calls for such severe weather that people’s safety, lives, homes and businesses may be in danger of wildfires.
As each weather situation is unique, PG&E carefully reviews a combination of factors when deciding if power must be turned off. These factors include:
- Low humidity levels, generally 30% and below.
- A forecast of high winds, particularly sustained winds above 20 miles per hour and wind gusts above 30-40 miles per hour.
- Condition of dry material on the ground and low moisture content of vegetation.
- A Red Flag Warning declared by the National Weather Service.
- Real-time ground observations from our Wildfire Safety Operations Center and from our crews working across the service territory.
Starting this year, PG&E’s decision-making process takes into account the presence of trees tall enough to strike power lines when determining if a PSPS is necessary. Every wildfire season is different, and the ongoing drought and dry conditions will determine the number of times PG&E will need to shut off power without compromising safety. We will always do our best to share what we know about the weather and our equipment as soon as we can, keeping in mind weather conditions can be uncertain.
