A brush fire that erupted Wednesday on a hill at the eastern edge of Norco scorched more than five acres and injured a firefighter before crews got it partially contained.
The blaze was reported about 1 p.m. in the 300 block of Cavaletti Lane, near Ridge Ranch Park, according to the Riverside County Fire Department.
The agency said 11 engine crews and two inmate hand crews, numbering about 60 personnel, were sent to the location and encountered flames at the base of a hill, in the vicinity of homes.
A firefighter suffered an undisclosed non-life-threatening injury while battling the brusher and was taken to a hospital for treatment.
Crews from the Corona and Riverside fire departments joined county personnel in trying to encircle the blaze, which was 50 percent contained shortly after 3 p.m. Crews were expected to have it under control before nightfall.
Thunderstorm cells moved through the area during the fire, but operations were not hampered. Lightning strikes were reported in the Riverside Metropolitan area, beginning about 1 p.m., but it was unclear whether a bolt ignited the fire.
