Another power outage in San Francisco has left thousands of Pacific Gas and Electric customers in the dark Sunday night. 

PG&E's website shows more than 11,000 customers lost power around 7:45 p.m. About two hours later, nearly 5,000 customers had their power restored.

The outage was impacting the Richmond, Golden Gate Park and Presidio areas. 

The utility company said the outage was due to an overhead equipment failure. 

San Francisco's Department of Emergency Management said all dark traffic signals should be treated as four-way stops. 

The city saw several outages through Christmas week as a winter storm moved through the area with heavy rain and strong winds. At the height of the outage, more than 130,000 PG&E customers were without power.

On Saturday, an outage impacted about 6,000 customers in the Golden Gate Park area.
