Firefighters halted the forward progress of a 16-acre wildfire in Riverside that threatened homes in the La Sierra Acres neighborhood Sunday.
The blaze was reported at around noon near Jurupa Avenue and Tyler Street, according to the Riverside Fire Department.
Ninety firefighters, two helicopters, two air tankers and three bulldozers were deployed to the fire while residents on the north side of Valley Drive between Mitchell and Chadbourne avenues were evacuated.
Two horses were also evacuated by the Riverside County Department of Animal Services.
“Structures were threatened but no reported damage,” the fire department tweeted at 2:56 p.m.
Fire officials said they believe an off-road vehicle crash may have sparked the blaze.
Authorities warned the public about strong winds and heavy smoke conditions to the south of Valley Drive.
Firefighters were on high alert Sunday as strong gusts and low humidity triggered a red flag warning for much of the Southland.
