Southern California's 2026 wildfire season opened with a violent surge on Friday, April 3, as a wind-driven brush fire ignited near Moreno Valley in Riverside County and grew from an estimated 5 acres to 4,176 acres within hours. The blaze, officially named the Springs Fire by Cal Fire, was still only 25 percent contained as of 10 p.m. Friday according to the Los Angeles Times. By Saturday morning, crews had pushed containment to 45 percent, according to Cal Fire's updated situation report cited by Fox 11 Los Angeles. Simultaneously, a second fire named the Crown Fire burned 345 acres near Acton in Los Angeles County before being brought to 74 percent containment by Saturday.
How the Fire Erupted
The Springs Fire was reported at approximately 11 a.m. Friday in the 15900 block of Gilman Springs Road in Moreno Valley, according to the Riverside County Fire Department. Initial crews arriving on scene estimated the blaze at roughly 5 acres. Within an hour it had reached approximately 50 acres. By 1 p.m., less than two hours after ignition, it had exploded past 1,000 acres according to Cal Fire, as reported by the Desert Sun. By 3 p.m. the fire had nearly tripled again.
Alex Izaguirre, a spokesperson with Riverside County Fire, told the Los Angeles Times that the initial spread rate caught firefighters by surprise. "Wind — that's the biggest issue right now," Izaguirre said. Cal Fire crews requested at least two air tankers and approximately 30 engines to assist in the initial attack, according to the Desert Sun.
The Crown Fire in Los Angeles County ignited at 11:23 a.m. Friday near North Crown Valley Road and Soledad Canyon Road in Acton, according to the Los Angeles County Fire Department. That fire had reached approximately 80 acres when firefighters first arrived, grew to an estimated 345 acres total, and was reported at 20 percent containment by midafternoon Friday, the Los Angeles County Fire Department said in a statement reported by the Desert Sun. By Saturday morning, the Los Angeles Times reported Crown at 74 percent contained and all evacuations lifted.
What the Wind Did
Meteorologists from two separate National Weather Service offices confirmed that strong Santa Ana wind conditions created the conditions for both fires to spread quickly.
Kyle Wheeler, a meteorologist with the National Weather Service office in San Diego, told the Los Angeles Times that easterly winds blowing from the Banning Pass drove the Springs Fire westward toward Lake Perris. "That allowed the fire to set up quickly and become the first wildfire of the season," Wheeler said. Wheeler noted that while the Springs Fire's point of origin was not directly inside the pass, it was still being pushed by sustained gusts of 30 to 40 miles per hour at the fire's location.
Riverside County valleys were under a wind advisory from the National Weather Service on Friday, with constant northeast winds forecast between 15 and 30 miles per hour and gusts reaching up to 50 miles per hour, according to the Los Angeles Times. The high wind advisory was expected to remain in effect through Saturday afternoon.
David Gomberg, a meteorologist with the National Weather Service's Oxnard station, told the Los Angeles Times that the Crown Fire in Los Angeles County faced similar conditions, with gusts measured at up to 55 miles per hour at that location. Gomberg noted that despite recent rains leaving some vegetation moist, "the winds and dry conditions are still enough to spread flames over grassy areas."
Wheeler warned that overnight conditions would provide little relief. Humidity was expected to remain between 10 and 15 percent. "It's going to be weaker winds, but with the flow still coming out of the east, we're not going to see an increase in relative humidity," Wheeler told the Los Angeles Times. Wind gusts were expected to pick up again Saturday afternoon before tapering off.
Evacuations and Impacts on Communities
The Springs Fire triggered mandatory evacuation orders for a large area east of Lake Perris, including multiple residential zones on both sides of Gilman Springs Road and the Lake Perris State Recreation Area, according to the Desert Sun. Moreno Valley College, which lies within the evacuation zone, issued an urgent statement on social media directing all students, faculty, and staff to leave the campus immediately and follow directions from law enforcement.
The Riverside County Fire Department also issued a drift smoke advisory for nearby cities including Riverside, Jurupa Valley, Menifee, Wildomar, and Lake Elsinore, the Desert Sun reported. Moreno Valley was seeing temperatures in the mid to upper 70s Fahrenheit on Friday, according to the National Weather Service.
An evacuation shelter was established at Valley View High School, located at 13135 Nason Street in Moreno Valley. A separate animal shelter was set up at the San Jacinto Animal Shelter at 581 South Grand Avenue in San Jacinto. A second animal shelter location was available at 14041 Elsworth Street in Moreno Valley, according to Fox 11 Los Angeles.
Gilman Springs Road was closed from Alessandro Boulevard to Bridge Street, according to the Desert Sun. Helicopter footage obtained by the Los Angeles Times showed darkened neighborhoods bathed in an orange glow as flames moved closer to residential areas late Friday afternoon. Law enforcement rushed to complete residential evacuations before nightfall.
By Saturday morning, Fox 11 Los Angeles reported that all evacuation warnings had been lifted for the Springs Fire, though formal evacuation orders for certain zones remained in place pending full verification of conditions.
The Terrain Problem
Beyond the wind, crews confronted difficult terrain that slowed direct suppression efforts. Tawny Castro, senior public information officer for Cal Fire Riverside, told the Los Angeles Times that ground access was a persistent obstacle. "The biggest hurdle for us at this point is being able to get firefighters into those areas with a terrain like that makes it a little bit more difficult," Castro said.
Maggie Cline De La Rosa, another Cal Fire public information officer, described the strategic response to the terrain challenge and the fire's proximity to homes. "Their biggest concern right now is the fire does appear to be approaching some residential areas, so they definitely have increased the tanker drops and the fire engines that are in that area," De La Rosa told the Los Angeles Times.
The combination of rugged terrain, strong winds, and limited access meant that air resources remained critical throughout Friday night, with tankers and helicopters making repeated water drops across the fire perimeter.
No Injuries, Cause Unknown
As of Saturday morning, neither Cal Fire nor the Riverside County Fire Department had confirmed any injuries related to the Springs Fire, according to Fox 11 Los Angeles. The cause of both the Springs Fire and the Crown Fire remained under investigation, with no official determination released by Saturday afternoon, according to Fox 11 Los Angeles and the Desert Sun.
No property damage figures had been confirmed by either Riverside County or Los Angeles County fire officials as of Saturday morning, according to Fox 11 Los Angeles. The Los Angeles County Fire Department similarly confirmed no injuries and no reported structure damage from the Crown Fire, according to the Desert Sun.
What Comes Next
The Springs Fire at 45 percent containment Saturday morning left roughly 55 percent of the fire perimeter still uncontrolled, meaning crews would continue battling the blaze through the weekend. Wheeler told the Los Angeles Times that wind gusts were expected to pick back up Saturday afternoon, creating the possibility of renewed spread before conditions eased. Humidity levels were forecast to remain critically low throughout the weekend.
Both fires together burned approximately 4,521 acres across two counties in under 24 hours, an unusually large combined total for early April. The Springs Fire's rapid growth from 5 acres to more than 4,000 acres in a single afternoon underscores what meteorologists have described as an increasingly volatile transition season in Southern California, where winter rains produce abundant grass growth that then dries rapidly under spring winds before summer arrives.
Cal Fire has not estimated structural losses or acreage burned on private land. Updates on containment are expected throughout Saturday afternoon as ground crews reassess conditions and wind conditions shift.
