Smoke visible across Stockton

The smoke plume remained visible across much of Stockton and neighboring communities during the afternoon, according to social media and KCRA reports.

According to emergency dispatch updates shared by AlertPage, the incident escalated into a third-alarm fire after heavy flames extended through the roof. Dispatch reports also indicated a partial roof collapse on the Charlie side of the structure.

A third alarm typically brings additional firefighters, engines, ladder trucks and command personnel from neighboring agencies. Mutual aid resources are commonly dispatched during incidents of this scale to strengthen firefighting operations.

The Stockton Fire Department said its priority was preventing the flames from spreading to surrounding warehouses and commercial properties in the industrial area. Viewer footage aired by KCRA showed firefighters using aerial ladders to pour water onto the burning roof while thick smoke continued rising into the sky.

Officials had not immediately reported injuries to firefighters or civilians. No evacuation orders had been announced as of the latest update.

The cause of the fire remains under investigation.
