Portions of 38 Counties and 25 Tribal Communities May Be Impacted by Widespread, Severe Offshore Wind Event Beginning Sunday
Customers Who Might Be Affected by the Public Safety Power Shutoff are Receiving the Initial Notifications Today, Two Days Ahead of the Potential Event
Four Extremes in the Weather for this Potential PSPS Event: Extremely High Winds, Extremely Low Humidity, Extreme Dry Fuels And Extreme Drought
Current Oct. 21 PSPS Event Update: Essentially All Customers Who Can Receive Electric Service are Now Restored After Current PSPS Event
SAN FRANCISCO, Calif. — Pacific Gas and Electric Company’s (PG&E) Emergency Operations Center, Meteorology team and Wildfire Safety Operations Center are working together and tracking a significant, offshore wind event starting Sunday that is forecast to have the driest humidity levels and the strongest winds of the wildfire season thus far.
PG&E has notified customers in targeted portions of 38 counties about a potential Public Safety Power Shutoff (PSPS) expected to start as early as Sunday morning (Oct. 25). Extremely dry, windy conditions with high gusts pose an increased risk for damage to the electric system that has the potential to ignite fires in areas with critically dry vegetation.
High fire-risk conditions are expected to arrive Sunday morning. High winds are currently expected to subside Tuesday morning (Oct. 27). PG&E will then patrol the de-energized lines to ensure they were not damaged during the wind event. PG&E will safely restore power as quickly as possible, with the goal of restoring most customers within 12 daylight hours, based on current weather conditions.
While there is still uncertainty regarding the strength and timing of this weather wind event, the shutoff is forecasted to affect approximately 466,000 customers in targeted portions of 38 counties, including: Alameda, Alpine, Amador, Butte, Calaveras, Colusa, Contra Costa, El Dorado, Fresno, Glenn, Humboldt, Kern, Lake, Lassen, Madera, Marin, Mariposa, Mendocino, Monterey, Napa, Nevada, Placer, Plumas, San Joaquin, San Mateo, Santa Clara, Santa Cruz, Shasta, Sierra, Siskiyou, Solano, Sonoma, Stanislaus, Tehama, Trinity, Tuolumne, Yolo and Yuba. Some customers in 25 tribal communities may also be affected.
The highest probability areas for this PSPS include terrain of the northern and western Sacramento Valley, Northern and Central Sierra as well as higher terrain of the Bay Area, including the Santa Cruz Mountains, Central Coast Region and portions of southern Kern.
“The safety of our customers and the communities we serve is our most important responsibility. PG&E’s 24/7 Wildfire Safety Operations Center and our team of in-house meteorologists continue to monitor weather conditions for this potential Diablo offshore wind event arriving Sunday morning and lasting through Tuesday morning,” said Michael Lewis, PG&E’s Interim President. “Initial forecasts indicate this could be our largest PSPS event this year so far. Our highest priority is to keep customers and communities safe and execute this event according to our plan and to then quickly restore power to all affected customers when it’s safe to do so.”
Customer Notification and Impact
The potential PSPS event is still two days away. PG&E in-house meteorologists as well as staff in its Wildfire Safety Operation Center and Emergency Operation Center will continue to monitor conditions closely, and additional customer notifications will be issued as we move closer to the potential event.
Customer notifications—via text, email and automated phone call—began late this afternoon, approximately two days prior to the potential shutoff. Customers enrolled in the company’s Medical Baseline program who do not verify that they have received these important safety communications will be individually visited by a PG&E employee with a knock on their door when possible. A primary focus will be given to customers who rely on electricity for critical life-sustaining equipment.
It is very possible that customers may be affected by a power shutoff even though they are not experiencing extreme weather conditions in their specific location. This is because the electric system relies on power lines working together to provide electricity across cities, counties and regions.

Due to forecasted extreme weather conditions, PG&E is considering proactively turning off power for safety. Windy conditions, like those being forecast, increase the potential for damage and hazards to PG&E’s electric infrastructure, which could cause sparks if lines are energized. These conditions also increase the potential for rapid fire spread.
“We’re seeing four extremes in the weather for this potential PSPS event: extremely high winds, extremely low humidity, extreme dry fuels due to the hottest average temperatures over the last six months according to records that go back 126 years, and extreme drought across the territory given lack of rainfall,” said PG&E’s Scott Strenfel, head of meteorology and fire science. “While temperatures are expected to drop heading into this event with cold weather expected in some areas, the high winds, low humidity, dry fuels and lack of rainfall continues to result in high fire hazard conditions.”
State officials classify more than half of PG&E’s 70,000-square-mile service area in Northern and Central California as having a high fire threat, given dry grasses and the high volume of dead and dying trees.
The state’s high-risk areas have tripled in size over the last seven years. No single factor drives a PSPS, as each situation is unique. PG&E carefully reviews a combination of many criteria when determining if power should be turned off for safety. These factors generally include, but are not limited to:
- Low humidity levels, generally 20 percent and below
- Forecasted sustained winds generally above 25 mph and wind gusts in excess of approximately 45 mph, depending on location and site-specific conditions such as temperature, terrain and local climate
- A Red Flag Warning declared by the National Weather Service
- Condition of dry fuel on the ground and live vegetation (moisture content)
- On-the-ground, real-time observations from PG&E’s Wildfire Safety Operations Center and observations from PG&E field crews
So far this year, PG&E has called 4 PSPS events, each of which produced safety hazards on our equipment. If PG&E had not de-energized power lines, these types of damage could have caused wildfire ignitions.

Community Resource Centers Reflect COVID-Safety Protocols
PG&E will open Community Resource Centers (CRCs) to support our customers.
The sole purpose of a PSPS is to reduce the risk of major wildfires during severe weather. While a PSPS is an important wildfire safety tool, PG&E understands that losing power disrupts lives, especially for customers sheltering-at-home in response to COVID-19. These temporary CRCs will be open to customers when power is out at their homes and will provide ADA-accessible restrooms and hand-washing stations; medical-equipment charging; Wi-Fi; bottled water; and non-perishable snacks.
In response to the COVID-19 pandemic, all CRCs will follow important health and safety protocols including:
- Facial coverings and maintaining a physical distance of at least six feet from those who are not part of the same household will be required at all CRCs.
- Temperature checks will be administered before entering CRCs that are located indoors.
- CRC staff will be trained in COVID-19 precautions and will regularly sanitize surfaces and use Plexiglass barriers at check-in. All CRCs will follow county and state requirements regarding COVID-19, including limits on the number of customers permitted indoors at any time.
Besides these health protocols, customers visiting a CRC in 2020 will experience further changes, including a different look and feel. In addition to using existing indoor facilities, PG&E is planning to open CRCs at outdoor, open-air sites in some locations and use large commercial vans as CRCs in other locations. CRC format will depend on a number of factors, including input from local and tribal leaders. Supplies also will be handed out in grab-and-go bags at outdoor CRCs so most customers can be on their way quickly.
How Customers Can Prepare for a PSPS
As part of PSPS preparedness efforts, PG&E suggests customers:
- Plan for medical needs like medications that require refrigeration or devices that need power.
- Identify backup charging methods for phones and keep hard copies of emergency numbers.
- Build or restock your emergency kit with flashlights, fresh batteries, first aid supplies and cash.
- Keep in mind family members who are elderly, younger children and pets.

Essentially All Customers Restored from Oct. 21 PSPS Event
PG&E has restored power to essentially all customers who can receive service that were impacted by the PSPS event that started Wednesday evening (Oct. 21). PG&E called the PSPS event due to a high-wind event combined with low humidity and severely dry vegetation, which together created high risk of catastrophic wildfires.
The Oct. 21 PSPS event affected about 31,000 customers in targeted portions of 7 counties with the majority living in Shasta, Butte and Tehama counties.
The top three recorded wind gust speeds from this PSPS event were 56, 55, and 52 mph in Shasta, Contra Costa and Butte counties respectively, with humidity and fuel moisture levels remaining low.
About 2,000 personnel were working on the ground or in 36 helicopters inspecting lines for damage or hazards.
Pacific Gas and Electric Company, a subsidiary of PG&E Corporation (NYSE:PCG), is one of the largest combined natural gas and electric energy companies in the United States. Based in San Francisco, with more than 20,000 employees, the company delivers some of the nation's cleanest energy to 16 million people in Northern and Central California.
