SAN DIEGO (AP) -- The lights are returning to parts of Southern California and Mexico after an electrical outage that affected millions of people.
San Diego Gas & Electric says that power has been restored to more than 710,000 customers as of Friday morning -- more than half of the 1.4 million whose homes and businesses went black Thursday.
However, the utility says some customers may not be back online until Saturday.
The blackout also caused a 3.2-million sewage spill that has closed some San Diego-area beaches. All public schools in the city also are closed Friday as well as local state universities and community colleges.
