A brush fire that erupted in the Santa Ana River bottom between Jurupa Valley and Riverside was 10% contained Tuesday after scorching 105 acres, though the progress of the flames was stopped and evacuation orders for residents near the fire were downgraded to warnings.

The non-injury blaze sparked about 11:10 a.m. Monday in the area of Jurupa Avenue and Van Buren Boulevard, less than a mile north of Riverside Municipal Airport, according to the Riverside County Fire Department.

Crews had been making steady progress encircling the fire when a separate fire sprang up about 3:30 p.m. ahead of the larger one, near the Western Riverside County Animal Shelter.

The fires blended into one under increasing southwesterly winds, and the consolidated blaze was burning close to homes south of Limonite Avenue. Evacuation orders were issued between Downey Street to the west and Avenue Juan Diaz to the east, encompassing hundreds of residences.

A second mandatory evacuation order was issued about 5 p.m. within Riverside, impacting residents north of Jurupa Avenue, stretching from Van Buren to the west to Anza Narrows Park to the east.

At 9 p.m., the department announced progress of the fire was stopped and evacuations orders for residents were downgraded to evacuation warnings. Those warnings remained in place as of Tuesday morning. It was unclear when
they would be lifted.

A temporary evacuation center was set up at Patriot High School in Jurupa Valley.

Sheriff's deputies closed all access points to the river bottom, except for emergency personnel.

At 4:20 p.m. Monday, Riverside Municipal Airport and Flabob Airport three miles to the northeast were shut down, and temporary flight restrictions were imposed, permitting only Cal Fire aircraft to come and go in the airspace.

Four Cal Fire water-dropping helicopters and two air tankers were called in to make runs on the fire.

Multiple engine, truck and hand crews from Riverside, Corona, Murrieta and Ontario joined Riverside County firefighters in working to get lines around the blaze.

At 12:40 p.m., the initial blaze turned north, immediately threatening properties near Kennedy Street and Riverdale Place in Jurupa Valley. A mandatory evacuation was ordered in the neighborhood, but at 1:50 p.m., the order had been downgraded to an evacuation warning.

A battalion chief at the scene Monday afternoon described the winds as "erratic," hampering containment efforts, and said the fire had the potential to grow to 500 acres. The flames were concentrated in Jurupa Valley, with the back end of the fire in Riverside.

As of 5:30 p.m., the winds were beginning to let up, according to reports from the scene.

No structure damage was reported, and neither were any injuries.

The cause of the fire was not immediately known.

The river bottom is dotted with homeless encampments, and during dry periods, fires from camping and cooking are a regular occurrence.
