A Medline warehouse fire in Tracy, California, destroyed a major medical supply distribution facility on Thursday, June 11, 2026, forcing nearby evacuations and triggering a large emergency response in San Joaquin County.
The fire was reported just before 1:00 PM local time at a Medline Industries distribution facility on the 5700 block of Promontory Parkway. Firefighters arrived to find a rapidly growing roof fire at the roughly 1 million-square-foot warehouse.
Officials said no injuries were reported. Medline said all employees and on-site personnel were safely accounted for.
Medline warehouse fire in Tracy spreads quickly
Authorities said the fire intensified because of high winds, low humidity, elevated temperatures and problems with the building’s private fire water system. Officials also said there was no water pressure inside the facility and that the warehouse sprinkler system was not working, making early fire suppression more difficult.
Police helped with traffic control and evacuations as thick smoke moved through the area. Residents affected by smoke were advised to stay indoors, close windows and avoid unnecessary exposure.
FedEx hub evacuated as nearby fire threat grows
Several warehouses southwest of the Medline facility were evacuated as a precaution. A nearby FedEx Tracy hub was also evacuated after the fire spread toward the neighboring property. FedEx said team members were safely evacuated and accounted for.
Around 7:00 PM local time, officials reported another fire at the FedEx site involving pallets and multiple big rig trailers. Firefighters brought that fire under control. Authorities said the building’s exterior caught fire, but the structure was not fully engulfed.
Local emergency declared as crews continue response
Tracy’s city manager declared a local state of emergency to keep emergency resources available. About 200 fire personnel from Tracy, Cal Fire and multiple Bay Area agencies responded to the scene.
Air quality officials said smoke had not initially shown major ground-level impacts because it remained elevated. However, authorities warned that smoke could settle overnight as temperatures dropped. Residents who smelled smoke were advised to remain indoors, close doors and windows, and use air conditioning or HVAC systems when possible.
The cause of the fire remains under investigation. Crews could remain in the area for several days as officials monitor hotspots, smoke conditions and damage at the site.
