A quickly growing brush fire in Southern California has spread at least 2,400 acres, prompting evacuations, according to fire officials.

"The fire continues to burn at a moderate rate," Cal Fire said, adding that hundreds of firefighters were working through the night.

Another fire has erupted in Riverside County on Sunday evening, prompting evacuation orders as it burns over one thousand acres of land right next to the already-raging Mindy Fire, according to officials.
