Live updates: 2 wildfires burning in Riverside County continue to grow, triggering evacuations

RIVERSIDE COUNTY, Calif. (KABC) -- Two wildfires burning in Riverside County triggered evacuation warnings and orders for residents on Tuesday.

A brush fire that erupted Tuesday in the Santa Ana River bottom in Jurupa Valley expanded rapidly in the direction of homes, leaving many residents under evacuation orders and warnings.

The Bain Fire was first reported at 11:22 a.m. Tuesday on the north side of the dry channel, in the area of Bain Street and Limonite Avenue, just north of the Hidden Valley Nature Center, according to the Riverside County Fire Department.

In the evening, the wind began to push the blaze toward the nearby city of Riverside, expanding evacuation orders and warnings to more residents.

While the fire continued to grow, the Riverside County Fire Department said crews made progress on containment lines around the perimeter.

There was no word on what might have triggered the fire. The river bottom is teeming with homeless encampments, and debris, cooking and warming fires occur year-round.

Meanwhile, the Verona Fire burning in Homeland jumped containment lines and continued to burn, expanding evacuation warnings and orders for nearby residents.

It was first reported at 12:20 p.m. Tuesday near Verona Road and Juniper Springs Road, which is in an unincorporated, rural area between Diamond Valley Lake and Lake Perris.
