San Diego Gas & Electric by Thursday had restored power to all customers affected by this week's Public Safety Power Shutoffs.

During adverse weather conditions, backcountry areas are prone to have electricity cut because they are often located in or around wind corridors. For example, Sill Hill in the Cleveland National Forest is a location where SDG&E’s network of 222 weather stations reports wind speeds of 70 mph and higher when Santa Anas blow through.

"Public Safety Power Shutoffs are approved by state regulators as an important safety tool of last resort to mitigate fire risk during dangerous weather conditions," SDG&E said. A map of current power outages can be found at sdge.com/outages. Officials said to never approach damaged infrastructure or downed power lines.

SDGE's website indicates as many as 58,000 customers could be without power due to the public safety power shutoff.

Tens of thousands of San Diego Gas & Electric customers could lose electricity later this week due to public safety power shutoffs during another bout of potentially dangerous Santa Ana winds.

San Diego Gas & Electric shut off power to nearly 900 customers early Tuesday to help reduce the chances of triggering wildfires as the latest Santa Ana windstorm moved through parts of San Diego County.
