There are 561 structures that are reported to be danger.
The fire broke out around 2:02 p.m. in the 63000 block of Highway 74, according to CAL FIRE’s Riverside Unit. Fueled by dry vegetation and hot conditions, the fire quickly jumped Highway 74 and is now burning on both sides of the roadway. As of press time, containment is reported at 5%.
