IDYLLWILD, Calif. (KABC) -- A brush fire erupted in the San Bernardino National Forest Wednesday, prompting evacuations in Idyllwild, where 600 homes were threatened.
The fire continued to spread rapidly amid a powerful Southern California heat wave. By early evening, it had spread to 4,700 acres with 5 percent containment, according to fire officials.
Authorities arrested a 32-year-old man from Temecula, identified as Brandon N. McGlover, for allegedly setting multiple fires in the area, including the Idyllwild blaze. He was booked on five counts of arson.
The rapidly spreading blaze, dubbed the Cranston Fire, ignited around noon. The fire burned near Highway 74 between Hemet and Mountain Center, according to San Bernardino National Forest officials. It later jumped Highway 243 as it continued to spread.
Authorities told Eyewitness News that approximately 600 homes were threatened by the blaze. At least five homes were destroyed.
