Two fires erupted in the San Diego area on Thursday afternoon, prompting evacuations. The Border 2 Fire, which broke out in the Otay Mountain Wilderness area east of Chula Vista and north of the U.S.-Mexico border, has burned approximately 4,250 acres, according to the California Department of Forestry and Fire Protection.

At least 27 people have died in the Eaton and Palisades fires, the Los Angeles County Medical Examiner said Thursday evening. Seventeen of the deaths are from the Eaton Fire in Altadena and 10 from the Palisades Fire, according to the medical examiner.

Over 1,100 firefighters were “strategically pre-positioned” across Southern California to address "ongoing critical fire weather," Cal Fire said.
