SACRAMENTO (CBS13) — Approximately 37,000 Pacific Gas and Electric customers will lose power Wednesday evening due to increased fire danger and strong winds.

Fewer customers will be impacted by the shutoff than originally forecasted. Earlier this week, PG&E estimated that 54,000 customers would lose power in the shutoff. Solano and Yuba counties were removed from the list of impacted counties Wednesday.

The outages will happen in waves, starting around 8 p.m. through the overnight hours. Power isn’t expected to be restored until Friday night. Counties in the scope of the PSPS event include Colusa, Plumas, Yolo and 12 others.

PG&E says a forecasted high-wind event combined with low humidity and dry vegetation creates a “high risk of catastrophic wildfires.”

This shutoff comes just a week after the previous PSPS event which affected more than 32,000 customers.
