A fast-moving brush fire broke out near Duarte on Sunday, sending thick smoke into the sky and prompting a large emergency response from firefighters on the ground and in the air.
According to reports shared by SGV CityWatch, the fire started in the wash west of the 605 Freeway near the 2300 block of Buena Vista Street. Initial estimates placed the fire at about five acres, but updates from people following the incident indicated it expanded to around 10 acres as crews continued battling the flames.
Fire engines, hand crews, and helicopters responded to slow the fire’s spread in an area filled with dry vegetation. Aerial water drops were used as firefighters worked to keep the flames from advancing toward nearby neighborhoods and critical facilities.
The smoke was visible well beyond Duarte. Residents from Glendora, Arcadia, and surrounding communities reported seeing large plumes rising into the air throughout the afternoon.
Residents Raise Air Quality and Fire Cause Concerns
As the fire burned, many residents shared concerns about smoke drifting into surrounding neighborhoods. Several people said the haze was affecting breathing, especially after days of poor air quality caused by recent fireworks and other nearby fires.
One resident said smoke had already worsened respiratory problems following Fourth of July celebrations and recent wildfire activity in the region. Others said they planned to remain indoors until conditions improved.
Community members also speculated about what may have caused the fire. Some questioned whether fireworks, homeless encampments, or other human activity near the riverbed could be responsible. At this time, however, there has been no official announcement regarding the cause of the fire, and authorities have not confirmed any of the theories circulating on social media.
The location of the fire, near the wash and close to City of Hope, added to public concern because of the area’s combination of dry brush and nearby development. Firefighters continued working to contain the blaze while monitoring changing conditions.
Brush fires can spread rapidly during periods of hot weather, low humidity, and dry vegetation. Even relatively small fires have the potential to grow quickly when wind and terrain allow flames to move through brush.
Officials continue to urge residents to stay away from active fire zones, avoid interfering with emergency operations, and monitor local emergency updates for evacuation notices or road closures if conditions change.
The fire serves as another reminder of the heightened wildfire risk across Southern California during the summer months.
As firefighters work toward full containment, residents are watching conditions closely and hoping the blaze can be brought under control before it threatens homes or businesses.
