SAN FRANCISCO — Pacific Gas & Electric warned Friday it might turn off electricity to thousands of customers in Northern California this weekend to reduce the risk of wildfires like the one sparked by power lines last year that killed 85 people and wiped out nearly 15,000 homes in Paradise.
The warning came as forecasters issued the year's first red flag warning of high fire danger in portions of the Central Valley and areas north of San Francisco starting early Saturday.
The National Weather Service said strong winds, low humidity and warm temperatures could raise the risk of wildfires.
The warning is in effect until 5 p.m. Sunday.
Once power is shut off, PG&E said its crews will inspect every de-energized line before they restore power, a process that can keep the lights out for days even after conditions improve.
