Authorities in Riverside County have issued urgent evacuation orders and warnings after a fast-moving brush fire erupted in the unincorporated Perris area, located approximately 20 miles south of Riverside, near Orland and Roth roads on Tuesday afternoon. Dubbed the Wood Fire, the blaze has already scorched dozens of acres and continues to threaten nearby residential zones amid dangerously hot weather conditions.

Fire Behavior and Immediate Response

The Wood Fire was first reported just before 1 p.m. on Tuesday, Aug. 25, near the intersection of Cajalco Road and Wood Road, specifically around Rider Street and Dreamglo Lane. California Highway Patrol initially fielded 911 calls regarding the blaze, which callers indicated started in a rubbish pile, possibly sparked by a resident clearing land. Initial reports placed the burn size at approximately 30 acres, but rapid expansion quickly pushed estimates to 45 acres, with later updates indicating coverage nearing 57 acres, and eventually reaching about 60 acres as of 3 p.m. The fire remains at 0% containment. To combat the rapidly advancing flames, nearly 170 personnel have been deployed, including three helicopters and 29 engines, alongside four Cal Fire air tankers that initiated runs on the brush. While the blaze initially burned at a dangerous rate through light grass and medium-sized brush across a lightly populated hillside, officials noted by 2:15 p.m. that its intensity had slowed to a moderate rate. Ground crews from CAL FIRE and the Riverside County Fire Department continue to work alongside aerial assets, significantly slowing its forward progress.

According to Cal Fire, authorities have stated the exact cause remains unknown. Officials also noted that it is currently unclear whether any structures are threatened or have sustained damage, and civilian injuries have not been immediately reported.

The blaze is advancing quickly toward Rider Street and Dreamglo Lane, moving generally in the direction of Highway 74. Sheriff’s deputies have shut down several roads in the immediate vicinity for public safety, including segments of Cajalco, Salter, Barton, and Riders streets. As of 4:30 p.m., additional closures were in effect on Salter Road at Fox Street, and at Juniper Road and Ida Leona Road. As operations continue, crews are taking advantage of numerous dirt roads and trails within the fire zone, utilizing them as natural fire breaks to contain the spread. Most of Harford Springs Reserve, a park featuring several hiking trails, is under an evacuation warning, while the northwestern part of Motte Rimrock Reserve, a biological field station on a rocky plateau managed by UC Riverside, also falls within a warning zone.

In a separate but concurrent incident, strong winds drove flames from an initially unexplained truck fire onto a nearby residence in the Perris Valley. Located on Westport Lane near Ashby Lane, the home saw flames actively tear through its roof while the vehicle remained engulfed nearby. Cal Fire crews were dispatched to the scene to suppress both the structure and vehicle blazes.

Residents in the affected zones should prepare to evacuate immediately. This is a developing situation that requires strict adherence to official safety directives.

Law enforcement and fire officials have established two distinct levels of evacuation directives. Mandatory orders, issued shortly after 2 p.m., currently affect zones RVC-1059 and RVC-1060, warning of an immediate threat to life. This evacuation area is bounded roughly by Orange Avenue to the north, Juniper Road to the west, Santa Rosa Mine Road and San Jacinto Avenue to the south, and Old Elsinore Road to the east. Residents must leave without delay. Evacuation warnings cover zones RVC-1171, RVC-1173, RVC-1174, RVC-1061, RVC-0972, and RVC-0973, prompting those areas, along with nearby agricultural businesses, to pack essential items and stay ready to depart if conditions worsen.

Impact on the Perris Community

The fire directly impacts residents living in the unincorporated valleys south of Riverside. Mead Valley and surrounding rural neighborhoods are experiencing heavy smoke and reduced visibility, which local authorities warn could degrade air quality further as winds shift. The Perris Library, located at 163 East San Jacinto Avenue, has been designated as an official shelter where displaced families can access cooling centers and emergency supplies. Animal owners are explicitly permitted to bring pets to this facility, ensuring households do not delay their departure due to concerns for their animals.

Regional Fire Season Context

Riverside County frequently faces elevated fire danger during late summer months when Santa Ana wind patterns begin to form and relative humidity drops significantly. An extreme heat warning is currently in effect for many parts of Southern California, including the valleys of San Bernardino and Riverside counties, forecasting dangerously hot conditions with high temperatures up to 110 degrees. In response to the prolonged heatwave, the Los Angeles County Fire Department announced it is augmenting staffing and pre-positioning personnel and resources to ensure a rapid response to wildfires. According to CAL FIRE, the state has tracked 4,731 wildland fires burning 260,000 acres so far this year. At this point last year, the state firefighting agency reported 5,543 fires that consumed 407,300 acres, while the five-year historical average stands at approximately 6,000 fires and 558,700 acres burned. While these numbers remain below the long-term baseline, single-spot ignitions like the Wood Fire highlight how quickly localized conditions can escalate into regional emergencies.

Safety Recommendations and Next Steps

As firefighting operations continue, residents within the warning and order zones should monitor local emergency broadcasts and avoid unnecessary travel near active burn perimeters. Authorities advise keeping vehicles fueled, windows closed, and important documents accessible at all times. Updates regarding containment percentages and potential zone lifts will be released by CAL FIRE and Riverside County Emergency Management as resources stabilize the situation.
