A fast-moving two-alarm fire tore through a Montebello strip mall on Thursday night, sending thick black smoke across Whittier Boulevard and pulling in fire crews from multiple nearby cities. Flames punched through the roof of at least one business as residents spilled out onto nearby blocks to watch. As firefighters continued to work the scene, officials had not yet released a final tally of injuries or damage.
How crews responded
According to NBC Los Angeles, the blaze was first reported around 7:21 p.m. at 121 E. Whittier Blvd., prompting Verdugo Fire Dispatch to quickly upgrade the incident to a second alarm. The Montebello Fire Department called in mutual aid from Monterey Park, Glendale, San Gabriel and San Marino as heavy flames and smoke poured from the roof. NBC Los Angeles also reported that NewsChopper4 was overhead, with smoke visible for miles around.
Businesses damaged and containment
CBS Los Angeles listed an auto shop and a firearms store among the businesses at the strip mall’s address and reported that firefighters heard possible explosions as flames burned through a shop’s roof. According to CBS Los Angeles, crews had the fire largely contained roughly an hour after arriving on scene. Officials told reporters the cause remained unknown.
Why commercial fires can escalate
Montebello has dealt with big commercial blazes before. A two-alarm fire at an auto-repair shop in 2017 caused explosions and knocked out power to hundreds of people, underscoring how solvents, paint and acetylene tanks can complicate firefighting and investigations, the Los Angeles Times reported. Those hazards can slow containment and stretch out recovery for nearby businesses and residents. Fire officials say scenes like this call for coordinated mutual-aid responses and careful origin-and-cause work once the flames are out.
Investigation underway
The cause of Thursday’s fire remains under investigation, and officials said investigators were on scene assessing the damage and trying to pinpoint where the blaze started, per NBC Los Angeles. For official updates and public-safety guidance, residents are advised to consult the Montebello Fire Department.
