Tracy warehouse destroyed in fire as city declares local emergency
The City of Tracy declared a local state of emergency Thursday, June 11, 2026, after a massive fire destroyed a 1-million-square-foot Medline Industries warehouse. Tracy Fire Chief Randall Bradley attributed the rapid spread to water supply issues, high temperatures, and wind gusts reaching 44 mph, according to official reports.
Fire crews responded to the facility along Promontory Parkway around 1 p.m. Chief Bradley stated that firefighters found heavy fire coming from the roof, which quickly extended into the rest of the facility. The blaze eventually engulfed the entire building.
Bradley reported that water supply issues hindered the response. He noted that the building’s sprinkler system was not operating upon arrival and that fire hydrants within the facility lacked sufficient pressure. A video from a warehouse employee appears to show the fire starting near the ceiling without the sprinklers activating.
Why did the Medline warehouse fire spread so quickly?
Chief Bradley described the conditions as a “perfect storm.” He cited a combination of low humidity, high temperatures, and winds of 10 to 15 mph, with gusts between 35 and 44 mph, as primary factors in the fire’s evolution.
The fire’s intensity caused multiple explosions, which Bradley confirmed came from products inside the facility and truck tires. The blaze also spread to big rig trailers and a large pile of pallets outside a nearby FedEx facility to the south.
While the exterior of the FedEx building caught fire, crews contained it before the structure was engulfed. FedEx confirmed in a statement that the fire did not reach their facility and that their priority remains the safety of their team.
How is the City of Tracy responding to the emergency?
The local state of emergency allows the city to activate pre-established emergency provisions and request state and federal assistance, according to the California Office of Emergency Services (Cal-OES).
Gov. Gavin Newsom’s press office stated the governor was briefed and dispatched resources from Cal Fire and Cal-OES to support the scene. Approximately 200 fire personnel and 100 support personnel responded to the main warehouse and surrounding grass fires.
The Valley Air District and the San Joaquin County Office of Emergency Services urged residents to stay indoors and close windows. They specifically advised sensitive individuals, including children and older adults, to take extra precautions due to smoke.
What is the impact on medical supplies and local businesses?
Sutter Health is among several health systems monitoring the situation. The organization stated that its supply chain teams have contingency plans to maintain access to critical supplies and do not currently anticipate broad impacts.
Amazon told CBS News Sacramento that it is following the directions of local authorities “out of an abundance of caution.” The fire occurred in an area home to several large distribution centers, roughly eight miles west of Tracy’s city center.
Tracy Police Sgt. Michael Richards, who previously responded to the 2018 Camp Fire, described the black plume of smoke as a sign the situation was “very serious.” He confirmed there have been no reported injuries and that all Medline employees are accounted for.
What may happen next?
Investigators are likely to examine the failure of the interior sprinkler system and the lack of hydrant pressure. Because the cause of the fire is currently unknown, a formal investigation into the origin of the blaze is expected.
Local authorities may continue to monitor air quality in the northern San Joaquin Valley as winds push smoke south. The city could potentially request further state aid depending on the duration of the cleanup and recovery efforts.
