Santa Ana Winds Drive Two Fast-Moving Brush Fires Across Southern California

A 5-acre spark at the 15900 block of Gilman Springs Road northeast of Moreno Valley took less than three hours to consume 1,500 acres Friday, driven by dry fuels and Santa Ana winds that turned a small roadside ignition into one of the fastest-growing fires Riverside County had seen outside of fall fire season.

By late Friday evening, the Springs Fire had scorched 4,176 acres with just 25% containment, threatening homes in the Moreno Valley Ranch neighborhood and tracking toward Lake Perris State Recreation Area. Fire officials warned it could reach 5,000 acres before the winds fully dropped.

Residents in nine mandatory evacuation zones, including areas north of Ramona Expressway, east of Lake Perris, and south of John F. Kennedy Drive in Moreno Valley, had to leave immediately. Five additional zones carried evacuation warnings. An emergency shelter opened at Valley View High School at 13135 Nason St. Those with animals could bring them to San Jacinto Animal Shelter at 581 S. Grand Ave. or Moreno Valley Animal Services at 14041 Elsworth St. Moreno Valley College shut down and evacuated all students and staff because of deteriorating air quality. Containment stood at just 5% by 4 p.m. when the fire was first reported at 10:59 a.m.; by late Friday night it climbed to 25%, but the National Weather Service had a Wind Advisory in effect for Riverside County through 1 p.m. Saturday, and authorities warned the overnight window would remain difficult.

A second fire complicated the regional response. The Crown Fire ignited around 12:30 p.m. near North Crown Valley Road and Soledad Canyon Road in Acton, in northern Los Angeles County, and grew from 80 acres to 280 acres within approximately one hour. Evacuation orders and warnings spread along the Highway 14 corridor. By late afternoon the Crown Fire stood at 20 to 25% containment, with no reported injuries or structural damage at either blaze.

Wind gusts fueled both fires with different intensities. ABC7 Meteorologist Danny Ramero reported gusts up to 55 mph near the Crown Fire and up to 35 mph at the Springs Fire. A High Wind Warning with gusts to 55 mph had been in effect through 6 p.m. Friday for the Acton area, while the Wind Advisory for Riverside County extended into Saturday afternoon.

Containment at the Springs Fire required 105 firefighters, 23 engines, two air tankers, and two hand crews. Cal Fire's Riverside Unit operated under a unified command alongside Riverside County Fire, Hemet Fire, Riverside City Fire, and the Pechanga Fire Department, with mutual-aid crews requested from neighboring counties. Aerial footage captured by AIR7 showed flames burning close to homes in Moreno Valley Ranch. The fire's perimeter jumped roads in multiple locations, and campgrounds and portions of Lake Perris State Recreation Area were evacuated as the blaze pushed eastward. The Riverside County Fire Department issued a drift smoke advisory for Riverside, Jurupa Valley, Menifee, Wildomar, and Lake Elsinore.

The April ignition underscored a shift in fire season timing. Traditionally, Southern California's peak fire window runs from late summer through fall, when Santa Ana winds are strongest and vegetation driest. A major fire of this scale in early April, driven by an abrupt onshore-to-offshore wind shift and residual drought conditions, reflects how climate-driven dryness is extending ignition risk year-round. Communities at the wildland-urban interface, where suburban development meets open chaparral, are increasingly dependent on mutual-aid networks built for fall catastrophes to handle fires arriving months ahead of schedule.

The cause of both fires remained under investigation.
