Napa, Sonoma counties included in potential PG&E power shutoff

High winds and dry conditions prompted officials at Pacific Gas and Electric to announce a potential public safety power shutoff for as many as 130,000 customers including some in Napa and Sonoma counties. 

Friday's announcement of early Monday's possible preventative outage could impact PG&E customers in 15 counties and five tribal areas. More than 8,500 northern Bay Area customers could see outages with Napa County taking the brunt of the impact. 

Officials said high-risk fire conditions are expected to arrive Sunday evening. High winds are forecast to peak on Monday and could linger into Tuesday. 

"PG&E will safely restore power as quickly as possible, with the goal of restoring most customers within 12 daylight hours, based on weather conditions," the utility said. 

PG&E said the areas most likely to be affected include the Sierra Foothills, North Bay mountains and portions of the Central Coast. This event is not expected to be widespread in the Bay Area. 

The possible power shutoff comes late in the season as dry conditions persist. The threat of fire season has typically subsided by October, but in recent years has extended into November. 

PG&E shuts power off proactively to prevent their electrical equipment from sparking wildfires to dry vegetation.
