PG&E officials say power was de-energized in the area for safety. At one point, more than 15,600 customers are without power, according to the PG&E outage map. By 10 a.m., that number had been brought down to just over 13,000 customers.

Several buildings have closed for the day due to the power outage, including the Stockton courthouse and City of Stockton Animal Shelter.

It’s the second major fire to happen in Stockton in less than 24 hours. Monday afternoon, firefighters battled a 3-alarm fire at a recycling plant a few miles away. Officials say the two fires are not related.
